Death of Iris (Mega Man X4)

Zero: Iris! Iris...
Iris: Zero...
Zero: Hang in there, Iris!
Iris: Please... stay away from Repliforce. Let's live together in a world
where only Reploids exist...
Zero: Iris, there's no world just for Reploids... it's only a fantasy.
Iris: Yes, I know... but I wanted to believe it... I wanted to live in a
world where only Reploids exist. With you...
Zero: Iris... Iris! Iris!! Iris!!! Iris.. Iris... Iris... No, this isn't
happening! There's no reason for me to go on! What... What am I fighting 
for!!!
