"The Legendary Executive" is hinted to be Wesker. This same character is voiced by D.C. Douglas and refers to his resurrection, rumors of his demise, etc. And he was involved in the events of BIO4, and Wesker's organization (the rival company) was referred to as "The 3rd Organization" during that incident as the only party involved besides the Los Iluminados and US Government.
Just to shed a bit more light on this.
In the Bio 4 guidebook Wesker has a timeline of his employment history which starts with Umbrella, S.T.A.R.S. then in 1998 it shifts to '3rd Organization' which definitely tells us its the Rival Company.
Also as we can see in the Bitores Mendez notes:
VILLAGE CHIEF'S NOTE
At Lord Saddler's order we've imprisoned the American agent and kept him alive, but I can't guess his true intention. I thought he should at least be imprisoned somewhere separate from Luis, but...
Although I don't think Luis would trust someone he first met, supposing the two of them join forces it would become a bit of a troublesome situation. If a third organization is operating, they couldn't overlook this opportunity.
But Lord Saddler is showing such an opportunity on purpose trying to expose them. There's an outside chance that if that organization's already crawled inside, it's possible our conventional plan may not only come to nothing, but the plan itself may be taken over.
Now I think he's daring to take a risk and smoke them out intending to prevent their sinister scheme. But we don't have any other choice but to trust Lord Saddler...
as well as:
WOMAN OF THE THIRD ORGANIZATION
We've confirmed a woman believed to be of a third organization within the castle. It seems this woman guided Luis.
Just before the agent arrived, the egg we injected into Luis was removed before hatching and information was passed to the United States. This woman must have contrived all of it.
Since this woman's objective is the "sample", we need to secure her before she contacts Luis. However, capture her in a state where she can speak, we also need to hear about the third organization from this woman.
By the way, since we'll hear about the third organization from this woman directly, Luis will no longer be necessary. After recovering the "sample", deal with him.
and:
LUIS AND THE THIRD ORGANIZATION
Luis' whereabouts are still unclear. He's probably using a special route his grandfather taught him, who was a hunter when he still lived in this land.
The thing he stole is surely hidden somewhere in the woods. If his grandfather were still alive we could've used him to locate it immediately, but...
However, how did Luis notice the egg injected into him? Furthermore, he already removed it with the drug before it hatched...
He stole it as well and escaped before that American agent arrived, and doesn't seem to have done it alone. Suitably, it's natural to think that a third organization other than ourselves or the United States are intervening in this.
In order to clarify this problem, we must catch Luis once again and wait for the effect of the drug still in his body to disappear, and inject him with a new egg. Then those pulling strings in the background should chirp. Those who interfere with our plan will pay the price.
"SAMPLE" RECOVERY COMPLETE
Although I issued another notice, Luis was executed at the hands of Lord Saddler and our order was able to safely recover the "sample." I wanted to resolve the situation by myself in this castle without troubling Lord Saddler, but above all I'm pleased that the "sample" has now safely returned.
It must be impossible for the
third organization's woman to foolishly interfere in this now. It's a crying shame that if Luis had just simply accepted becoming our associate, he could've been useful in the wonderful world our order will rule.
Regarding the two Americans, I received word from Lord Saddler that he'll entrust everything about them to me. To repay his trust, we will capture Ashley at any cost and send her to Lord Saddler's location.
and so on.
I don't think there is any dispute of whether the 3rd Organization is the Rival Company.
H.C.F. is just the Special Forces of this company but because the company name was never revealed in any materials Capcom just references it with that title now.
Here is some more files from Ada from Separate Ways:
REPORT #1
The true purpose I must accomplish. I was attached to this mission as a stepping stone to that. My true intentions must not be realized by anyone until after it's done. It's no use to merely hide in the background. It'll be necessary to appear before them occasionally and give guidance.
First, I want to sort the stage background. The Los Illuminados cult led by Osmund Saddler have released the seal from the Plaga parasite. I intend to discuss Saddler's "secret art"
and the information that we, the "organization", have obtained at this stage.
The feudal lords of the Salazar family are said to have used a special ability from generation to generation to control the Plaga. We've hypothesized that this may be a special communication method via sound or sound waves. "Commands" are conveyed in a range only the parasites can detect in order to manipulate them at will. In a nutshell, it's the principle of a dog whistle.
This theory was inferred from the fact that an organ which seemed to sense sounds was ascertained from tissue of the parasite that we initially obtained. All the cult's leaders once carried a cane for special religious services. Is there some sort of trick to this or is there vocalization using a particular range? There's still no conclusive evidence for this hypothesis, so it doesn't go beyond the realm of speculation.
Including those verifications, the
"Plaga sample acquisition" is the matter which takes first priority above all else in this mission. It's also a proof of trust I must fulfill for the "organization." The pieces are beginning to move and the countdown has begun. There's no turning back now.
REPORT #2
In this incident with various entanglements, he...
Luis Sera, is relatively simple. His affiliation with any organization can't be confirmed, and I've concluded that he's acting on his individual will. It was I who recommended him to the "organization" as a key person in this mission. That's because I liked his "enthusiasm", which oozes with humanity.
It was fortunate that I was able to accidentally intercept his e-mail for help from a research facility.
For some reason, he didn't seem to trust the police and the e-mail was sent to a friend from his college days. It seems he didn't know his friend was already dead; anyway, that's how I was able to plan contact with him.
Between his Plaga research, he seems to have advanced his own investigation about the cult's background. Some of that was also written in the e-mail; his sharp insight pressed for the truth in all aspects. This observational eye was probably the ability Saddler hired him for. However, his ability has gotten too deep into the cult and aroused Saddler's suspicion.
When I told him of my true nature, he requested to be taken into protective custody. "I have no love for the Plaga or the cult, I just want to get away somewhere safe and return to a quiet life..." As collateral, I ordered him to steal a "dominant species Plaga sample" for evidence.
It also seems he's one of the few people to have somehow gained Saddler's trust. I planned contact and expected it'd be relatively easy to obtain the sample. However, the cult won't take kindly to his escape. I'll have to guide things myself, to some extent.
REPORT #3
Jack Krauser... the "organization" conducted thorough background checks on this man. His personality and capabilities in carrying out military operations were checked for no issues. If he merely possessed halfway skills, he would jeopardize the rest of us.
In conclusion, he's an excellent mercenary. He serves no more nor less as long as sufficient "compensation" is promised. I understand his behavior patterns temporarily showed threatening movement to some extent.
Wesker hands down all instructions for this operation directly. It was also Wesker who ordered Krauser to infiltrate the cult as a spy in order to obtain the "sample", and also opted for a united front with me. This was probably for the implication of monitoring each other.
Krauser's already in the cult and has probably fallen to the charm of the Plaga and its symbol of "power."
As a result, I also predict he'll become a presence which may soon harm us, the "organization." But in a sense, this may be a necessary development. I'm using him to play the essential role of "disrupting the stage."
Since the stage itself is destined to be destroyed and erased sooner or later... But unluckily for him, that must be hidden from him in order to achieve my objective and keep things going as they are.
REPORT #5
I was somehow able to patch up the small rip. I think the mission can be called a success. I was able to safely achieve my original objective of acquiring the sample.
I sent Wesker a different present. As per the order of the "organization." Feigning collusion with him was quite thrilling too.
Albert Wesker... Wonder what his next move will be. I feel like I've merely just gotten a taste through this mission. To him, Umbrella was once a symbol of power which could be used to support and realize one's ambitions. However, the "umbrella" was torn and that fantasy was shattered.
Having lost protection, those behind the black intrigue have scattered and now squirm in their quest for a new "umbrella." They hate the light of the sun. As it makes them conscious of their own repulsiveness. Wesker intends to raise a new larger and stronger "umbrella."
The giant pharmaceutical company "S" supplies drugs to public medical institutions around the world. Evidence has confirmed that Wesker contacted them after Umbrella's collapse. His next "starting point" will probably be there.
The "organization" must observe carefully.
But Wesker's not stupid. He knows exactly what I and the "organization" are thinking. Although we're both swimming against each other, we're meant to swim together. At the moment, there's still some pleasant leeway. I've safely taken one step forward to my true purpose. There's one thing I can say with certainty... The battle's not over yet.
Their also referred to as the Agency in BIO 2 by Annette Birkin.
THEY PLAY SUCH A BIG ROLE BEHIND THE SCENES AS BEING UMBRELLA'S MAIN RIVAL IN THE FIRST HALF OF THE SERIES:
*they hired Ada Wong to infiltrate the Spencer mansion and get John Clemens to fall in love with her so that she could smuggle out a sample of the T-Virus.
*they used data given to them by Wesker after the mansion incident to sabotage the Hunter B.O.W. program and ended up creating a more superior one (as well as the Sweeper subspecies) which led to Umbrella scrapping the Hunter project and creating the failed Anubis as we never saw it again.
*the Hunter surveillance drones they created were a part of their outstanding technology that they provided for Krauser as well that he used in his fight against Leon.
*they then hired Wesker to work alongside Ada to recover a sample of G.
*Wesker had a secret objective of saving Birkin and recruiting him into the company.
*they acquired data on the Nemesis T-Type from Raccoon City.
*they had a spy on Rockfort Island for 3 months that exposed Alexia.
*they were at one time the only organization to have possession of T-Veronica thus leading to the creation of the Jabberwock S3.
*they made alliances with Javier and tried to get him on board (through Wesker) to jump ship from Umbrella and to join them.
*they used Krauser as a mercenary to do contract work for them.
*they hired a spy to work for them in the Caucasus Mountains for them.
*the Russian base that Chris and Jill invaded in Umbrella's End was partially funded by them which is very interesting as it tells us they were a 'legitimate public' organization.
*their money provided weapons, vehicles and equipment for the Umbrella's End mission which in turn allowed them to bug all the items for their surveillance devices so that they could listen into everything.
*this was a double kill as they were helping finish off Umbrella while at the same time trying to gather as much data as possible from them since Wesker never provided the U.M.F.-013 to them.
*so...their first big downfall came when Wesker stole the U.M.F. -013 and used it for himself instead of providing it to them.*
this is when Ada Wong does her part to watch him in RE 4 under their orders as they no longer trust him.
*their second big downfall came from Wesker using up their resources to find Spencer:
NO. 12 ALBERT WESKER
The Mansion Incident, the tragic incident in Raccoon City, the incident in the Umbrella Antarctic Laboratory beginning from Rockfort Island, the incident in the Russian Caucasus Laboratory, and the kidnapping of the U.S. President's daughter.
A man is confirmed to have affected the limelight and background in all these cases. That is Albert Wesker. It's not an exaggeration to say that this incident was sparked by his actions.
Up to this point Wesker had obtained many viruses and organisms, including the t-Virus, G-Virus, t-Veronica and the Plaga. Armed with these, he rose within Umbrella's rival company and obtained status, wealth and honor. Materially he was contented.
But a discomfort, which had always been there, continued to exist inside him. It was Umbrella founder Oswell E. Spencer.
For a long time Wesker could not fathom Spencer's true goal. He had said that his superfluous capital investment into Bio Organic Weapons (B.O.W.) was abnormal. Originally the merit of a biological weapon was that it could be developed cheaply. Thinking about combined use with a normal weapon system, extreme B.O.W. development was thus far unnecessary. Why did he persist in B.O.W.'s? In order to search for the answer, Wesker placed himself in the Umbrella Intelligence Division.
The question came to flare up in his head again. To answer the question, Wesker searched for Spencer's whereabouts. However after Umbrella's collapse Spencer had disappeared from the limelight and gone missing. He used everything he had.
Using all of his organization's power and money as well as time, Wesker finally discovered Spencer's location.
On an early autumn night of ceaseless thunder, Wesker visited Spencer in an old European castle. When he caught sight of Wesker, Spencer considered whether to be surprised and shone a dark joy underneath his shriveled eye sockets.
"You've returned..."
Spencer's laugh was mixed with dry coughs.
Again, Wesker was unable to measure this old man's true intentions. He'd experienced this feeling many times since the time he was in Umbrella. A sticky presence emanated heavily from the old man, whose feeble body was like a withered branch. The power of an absolute and engulfing goal had danced in the palm of his hand. This was the true nature of his biggest discomfort, the nemesis he had irritated himself with. Spencer began to talk as if he had detected it inside him.
Bio Organic Weapons development was only a means for allowing him to accomplish his true goal. His true goal was the forced evolution of the human race by means of a virus. The end of Homo sapiens who had lasted 200,000 years, and the birth of a neogenetic humanity. His true goal was to create a Utopia by and with the new humanity, and to become a god there.
There were three things he required to realize this distorted ideal.
Firstly, the "Progenitor Virus." Without the Progenitor Virus, his Utopian creation was merely a dream for him. The existence of the Progenitor Virus dragged that dream into the real world.
Secondly, "Umbrella." Development for weapons application purposes was perfect to advance Progenitor Virus research without anyone realizing his true intentions. Therefore, the profits obtained by Umbrella were merely secondary for him.
And the third was "Wesker." The Utopia envisioned by Spencer. The people living there had to be ideal humans. Then what was an ideal human?
A nascent humanity whose evolution was prompted by the Progenitor Virus. That was the main premise, of course. However, what happens if a person whose evolution is prompted is a man who doesn't comply with Spencer's own will?
Even if they evolved and obtained superhuman bodies and intelligence, the person's knowledge, moral values and common sense wouldn't change. Suppose lazy and incompetent people were chosen as reborn humans, what would happen? They would become a stain polluting his faultless Utopia. It was a situation that needed to be avoided at any cost.
Therefore Spencer decided to carry out a single plan.
The plan was called the "Wesker Project" after the name of the chief researcher.
According to the plan, several hundred children were gathered from every race around the world. They were children born from parents brimming with abilities. He thought that if he couldn't change their knowledge, moral values and common sense, he should endow them with these things he desired from the bottom up.
Each was given the name of "Wesker" and the gathered children were set free around the world. Naturally, extreme surveillance was attached without them noticing. Their fields were different but each would grow up in an environment where they received the best education.
Several years later, one particularly excellent and recognized young man was sent to the "Umbrella Executive Training Center" in Raccoon City. It was the Wesker given the name "Albert."
Albert Wesker's subsequent actions pleased Spencer. He was able to tell that this Wesker had sufficiently met the standards of his nascent humanity. Moreover, the same might've been said for other Weskers.
Therefore Spencer decided to push the plan forward to the next stage. He decided to administer an experimental stage virus to all the Weskers.
This was a "screening", so to speak, to ascertain the truly excellent Weskers. Some would be forcibly administered the experimental stage virus as part of their treatment, others on the recommendation of close friends.
Naturally, Albert Wesker was no exception either. He received the experimental stage virus from his rival William Birkin and injected it himself for his scheme.
It could be said that the result of this "screening" was too severe. Almost all Weskers died, only a few surviving. One of the survivors, Albert Wesker, disappeared somewhere.
It was "Spencer's presence."
That was the true figure of the uneasiness Wesker had continued to feel. Wesker wasn't interested in Spencer, his curiosity was programmed. And in accordance with Spencer's expectations, Wesker had returned.
However, Spencer had just one miscalculation. The safeguard kept in the depths of Wesker's psyche was effective only because he was a mystery. There was no reason for Wesker to be quietly bound by it if he understood his true nature. Furthermore, he had grown old and was an elderly man all the more close to death.
"God... I see. I will take over"
With those words, Wesker severed his own chains.
Was it mere chance that his former subordinates Chris Redfield and Jill Valentine delved in? Wesker thought of it as a revelation. The Homo sapiens who had interfered with his own plans many times.
It seemed there was definitely still room for evolution.
Wesker murmured in his heart.
Then, Wesker survived that place and in possession of funds, research results and viruses using a position he'd gained in a certain pharmaceutical company, he crept underground again. He began ascending the steps for becoming a next-generation god, to carry out the veritable "Uroboros Project."
so their such a critical part of the first half of the series, it's such a shame that they just disappeared like that never to be used again save for a slight mention in a file in Bio 7.
Now it is of course quite possible that it's not him at all in any form. However, that is the implication they are going for. Whether or not it's misdirection or a red herring etc is unknown. But the fact that they are deliberately tying Wesker to Blue Umbrella indicates a high probability of the rival company being involved.
I hear ya, maybe indeed they will come to light but I'm really not feeling it a this time, such a shame.
