Separated at Birth?

For your consideration:

Lex Luthor.

Auger.

Power armor he built himself.

Power armor he built himself (though to be fair he technically didn't design it [he did make his own modifications to it, though]).

Both have issues. (One is insane, the other merely cranky.)

Both are bald, with rather heavy eyebrows.

Both ran for president. (Both won.)

And both have enemies who took issue with their election.

Decide what the truth is for yourself.
