cynthia has been in the last 9 pokemon games released, not counting conquest and that stuff. While i'm sick of seeing cythia everywhere it makes more sense to put her in instead of someone like wallace that some of the newer people won't know.
I would like to see colress come back, despite his rather unusual sense of style when it come to headgear
and i think that it only makes sense that blaine was involved with mewtwo, he is a scientist that lived on cinnabar right near the pokemon lab, and is on good terms with mr.fuji,
seems like played a part in the creation of mewtow
