Three Primary Human Bloodlines

It seems that Set sired the three bloodlines out of the garden of Eden.

A = Abel (possibly Adam as well)
C = Cain
S = Set / Seth

In comics both Apocalypse and Captain America have big A's as their symbol.
The X-Men - X stands for Cain, so that's Cain's bloodline.
Now who do we know, that is a superhero and has a big S on his chest?
Superman gets his powers from the RED sun. The sun is RED at sunSET.

Elenin anagrams to Enlil. The failure of comet Elenin signals the rise of Enki / monkey king aka Kein which anagrams to Nike and also is Cain.

Cain and Abel

Set (mythology)
