But just incase you're in a rush, here's a summary of it:
"Crimson tends to be a focused individual - he will not deviate from a mission easily, although personal feelings can sometimes get the better of him. Generally, he tends to be a bit of a joker and is good-natured. He will support anyone who truly is in need, but he does not suffer fools or angered folks gladly."
Zeroshi is usually quiet and keeps too himself mostly. But the only reason he does that is to keep Omegasis in check(2nd soul that he was born with)But he is always up for a challenge and when there is someone in trouble, he will help them no matter what.
Edit: Oops i forgot Omegasis' sprites http://zeroshisprites.smackjeeves.com/comics/844588/omegasis/
And so i don't go to deep with details Omegasis is triggered by anger and has an exact opposite personalty than Zeroshi.
