Nod to Mrmind which would you rather be a Kryptonian, Martian or Eternal
Unlike Mr Mind post, the Kryptonian vs Sayans the abilities are somewhat different. Kryptonians, Martians & Eternals have very similar abities. lets look at the plus & minus.
Kryptonians- will have the easiest time developing their powers and of the 3 races will have them at the highest lvl.
weakness: Kryptonite & magic
Martians- simply put are the swiss army knife version of the superhero community, think of a power the probably have it in spades.
weakness: Fire, the easiest substance to get in any universe. DC, Marvel or real
world.
Eternals-they potentially can equal even surpass a Martian in the number of powers, but you have to spend time to develop your powers. Otherwise you're basically a low tier superhero.
weakness: It takes them several hundred yrs of training to become very powerful if not thousands of yrs. This is the main reason which tend to makes them specialist which doesn't take as much time. They tend to be either super-strong, super-fast or have incredible transmutative abilities or TP. Thanos, Ikaris, Makkari and for a little while Hyperion are considered Eternals which gives some measuring stick of their potentials. Hyperion is the only 1 who became powerful in less than several hundred yrs but IIRC Marvel reconnected the fact that he was an Eternal from an alternate Universe away.
