species: robotically modified human.
created by: Dr. Cain, after the space-colony crash from megaman X4.
KB.5 was originally human, but... when the space-colony crashed into the earth, he and thousands of other people and reploids died. he was one of the few bodies practically perfectly in-tact, and he was found by Dr. Cain. the doctor robotically modified him, so he'd be no human nor reploid.
I'll upload a pic of him soon... when I created one
this is all I got to tell of him so far... his complete story is in my fan-fic for speedy's contest
