I like Dragonspine's design and origin (especially use of an established name as an alter ego). Frisch I like the idea of knowing more about the planetary system that Krypton is part of, and knowing that Krypton may not have been as Utopian as people might think. God Killer looks like an evil Apha Centurian, yet I feel like there should be a good solid reason for him to hate Superman, since what you have here sounds like Jealosy which is different. What if instead he was from Zandia a nation run by villains right and during a battle Superman was involved in on those very shores he accidentally kills one of Juan's parents (giving him the motivation to go after superman). Armiv2 I like the look of your character so you say his powers have a short range, yet the ones he has seem pretty good, seems like Gamut is one foe you would try to take out before he could bring his powers into play, is he an alien? If so which planet is he from? Kryptonex with his powers and looks it seems he could be a hero also, and can he control which power/s he gives another person/animal?
