Spent about a week in between a bunch of other responsibilities putting this together for a multiverse-themed art contest in a friend's discord server! All of these characters are alternate-universe versions of Nuclear Fission (235), who holds title of "Nuke Prime", the original. Their universe tags each correspond to an isotope! Uranium, Thorium, etc.

For anyone confused about the C&C: Generals tag; Final Flash (239) is a ponification of the China faction's 'Nuke Cannon' unit. Hence the armor, red star, and... well, the nuclear cannon sitting on her back!

Characters, universe tags, and tl;dr personalities in order of appearance:
235 - Nuclear Fission - "local mad scientist mellows out and becomes single father of 14"
232 - Bright Future - "apologizes for apologizing and WILL cry"
223 - Nuclear Dawn - "4chan user actually as intelligent as he thinks he is, world trembles in fear"
293 - Halflife - "the concept of time literally does not exist in his dimension; the depressed hoe still manages to be late to everything"
233 - Nukette - "local mellow scientist goes mad and becomes single mother of 14"
209 - Nuclear Powered - "14 local mad scientists become parents to a single android; he flexes on them by not having any mental illness"
239 - Final Flash - "why yes, we DID give that mare access to a pony-portable nuclear cannon, what could go wrong?"
003 - Cold Fusion - "I'm the sexiest researcher at this energy convention"
226 - Bombshell - "I'm the sexiest assassin in this illegal crime ring"
210 - Polyatomics - "marecel literally discovers the concept of atoms; still can't get a date"
