When did she die? I played all the old NES versions and some of the GC, GBA, and DS versions but missed all of the SNES and some for those other systems. I assume it was somewhere in that segment of the series but where/when/how? ?_?
Rock/Megaman, Roll, Bass, Rush, Treble, and every other original MM bot never really "die" canonically. They are just never mentioned in other series.
In MMX, Dr Light is "alive" as a computer consciousness. Dr Wily is also vaguely mentioned. But no other original MM character is mentioned in the X series, so no one knows what happened to Rock and Roll.
He'd make a better President than Obama that's for sure :U (No offense to those that like Obama but the dude can't even make up his mind and doesn't know what he's doing. We need somebody who DOES know exactly what they're doing.)
