Specter is a Woobie, Destroyer of WorldsHe was always very intelligent, pretty much on the level of a human, but was still considered a lesser creature and forced to perform for other humans at the monkey park. He's not really evil, he's just misguided and thinks Humans Are the Real Monsters, and wants to prove himself to a world that wouldn't treat him as an equal.
Monkey White is Cranky Kong.Think about it. Both of them are old, crotchety primates who are genius inventors. White's metal diaper/pants thingy could be futuristic leg support as opposed to Cranky's two canes.
