Mr. X

Mr. X is a B.O.W. in the Resident Evil series made by Umbrella during the late 90's dispatched to kill everyone in Raccoon City. Expectable, honestly. What was unexpected was for him to join the ring and end up body-slamming everyone with no true goal, even going against Albert Wesker at some points.

When Mr. X tries to escape, Miles traps him in his Chess Dimension where he begins his interrogation.

>What were you attacking Wiseau for? Attacking? Why would I do such a barbaric thing?

I don't recall ever attacking this man. >I have clearly heard you punching him before! Now that you say it, that might have happened...

But he was asking for it! He sent his goon after me...

I misspoke, forget about it. I meant to say that... He's a loon.

It's dangerous to have such irrational men walking around, so I was trying to tie him up. >Is it that old man in a wheelchair? ...You mean Delta?

I'm not entirely sure about his motivations, but I'm assured that he's his own man.

It can't be him. >Is it Wright? ...

...Interesting.

So you really think your dear friend is someone's henchman? >Is it La Parka? La Parka...?

So you think he's the mastermind.

May I ask why did you come to this conclusion? Edgeworth: Who else would have goons in a place like this?

This is a goddamn death game!

La Parka controls everything here! Your way of thinking isn't incorrect, but unfortunately, you're mistaken.

This man's goon is someone else. >Is it that ninja? You are correct. To be clear, that ninja isn't just his goon, you could say he's like an offspring.

...

So I suppose you won't be preventing me from giving him a good beating now... Hold on! We haven't dealt with the elephant in the room yet! >Who's your master? Edgeworth: There's no way a monster like you is just wandering around on its own! ...

You know, I'm deeply hurt by your words...

And shouldn't YOU know by now? >Are you working for La Parka? You misunderstood... I wasn't referring to...

Besides, I'd prefer to not refer to myself in third person. >Why are you suddenly able to talk now? I was always able to, I just chose not to.

I had to explain myself, which is why I talked. Is there a problem with that? >What's your true goal? You know, I was really desperate too. I'm in quite a pickle here.

If I don't subdue this man... Then people begin to gather and X concedes to reveal the truth. X then begins explaining the story of Wiseau, and how it began at SC Labs...

When Richtofen infiltrates it to recover The Focusing Stone, The Cookie jumped at him. A parasite inside the stone had attacked him. After Kojima had made his own modifications for the stone, SC Labs were trying to push it even further, to become humanity's hope. The parasite was never reported and the body snatching was written down as another one of it's abilities. However, from the unreported effect came distrust that concluded in the entire security staff quitting, leaving the facility unsecured for a single day, and that lucky day was when Richtofen striked, and his body became possessed... by the thing in this very room.

Mr. X then eats part of the parasite, causing the stone and Richtofen to separate. Mr. X the grabs the Focusing Stone and plans to use it to stop the death game, when La Parka's TV turns on. He reacts with extreme discontent upon seeing the artifact. Mr. X then uses its power to shut down the connection to the other universe, and also the power of the facility.

Episode 10
With their only chance, everyone tries to escape through the newly discovered "Wild Ride Door". However, what they find, is the lifeless bodies of those sentenced to the wild ride.
