Greed: You've never killed anyone, have you, kid?
Edward Elric: What's that got to do with it?
Greed: I'm saying you lack the guts to kill. You'll never beat me like that, and you'll never beat the other homunculi either. So I'll help you find the guts now... by showing you some of your own...
Edward Elric: I didn't come here to negotiate! If all you homunculi are mistakes created by alchemists, the results of their sins, well then alchemists should be responsible for correcting those mistakes, starting right now!
Greed: Huh... all right... I didn't want to have to show you this since it does get a bit ugly, but since you're getting all serious on me, then I'll get serious too.
[Greed transforms into his Ultimate Shield form]
Edward Elric: What the?
Greed: This is my real form... come and get it!
