Honda: I'm sumo, brother. My body could be in one place, my mind another.
Balrog: Next time your mind leaves, tell it to bring back a pizza.
Bison: Dee Jay, has the AN deposited the twenty million in my Swiss bank?
[Dee Jay checks and finds the account empty.]
Dee Jay: Hell no, General.
Carlos Blanka: Help me!
Colonel Guile: I'll help you. Then, I'll make them pay.
Bison: The temple above us was the wonder of the ancient world. Bisonnapolis shall be the wonder of my world. I think the food court should be larger. All the big franchises will want in.
Bison: Now, Miss Zhang, you'll witness firsthand the power that you spurned.
Zangief: General Bison is a bad guy? If you know then why do you work for him?
Dee Jay: Because he paid me a freakin fortune, Man! If you know what's good for you you'll save your own ass.
Zangief: ...you got paid?
Victor Sagat: This isn't over, Guile. I own this city.
Colonel Guile: Well, I'm the repo man, and you're out of business.
Colonel Guile: Bison. Are you man enough to fight me?
Bison: Anyone who opposes me will be destroyed.
E. Honda: Watch your back, Li.
Chun Li: Oh, I didn't know you cared.
Balrog: We don't. You're the only one who can pay for our expense accounts.
Bison: Merely educational software. Why does he find it disturbing?
Dr. Dhalsim: Because, unlike you, he's not psychotic.
Victor Sagat: Vega is the greatest cage fighter since Iron Fist.
Ken: What happened to him?
Victor Sagat: He retired... and became me.
Bison: You have made me a very happy man.
Colonel Guile: And next, I'll make you a dead one.
Zangief: Quick, change the channel.
Capt. Sawada: A single boat against everything he's got? The pilot would have to be out of his mind.
Colonel Guile: Luckily, Bison has driven me crazy... so I'm going to do it.
Bison: Game over.
Bison: All I want to do is rule the world, is that so much to ask?
Answer: In his fight with the guard, Dhalsim gets knocked into some chemicals. This presumably changed him. This is also likely the explanation if he had to do any signature moves from the games, which thankfully, he doesn't.
