15. Kremlin

(Ex Machina, Wildstorm)

Ex Machina is one of the most underrated comics of all time. Seriously, it is friggin' excellent, and no one ever talks about it.

The series follows Mitchell Hundred, mayor of New York City and former superhero The Great Machine who, in his world, stopped the second plane on 9/11.

He bankrolled that fame into a successful campaign for Mayor, and the series tracks his time in office. However, being in office means that he was retired from being a superhero, and his former mentor and current friend Ivan "Kremlin" Tereshkov really didn't like that. Kremlin spent much of the series trying to prod Mitchell out of the White House and back into the jet pack.

HUGE MAJOR SPOILERS FOR EX MACHINA NOW! PLEASE SKIP AHEAD IF YOU DON'T WANT TO SEE THEM. The last issue follows Mitchell's downfall as he made sacrifices and ill-advised deals to cement his campaign for president. When Kremlin threatened to tell everyone that Mitchell rigged his mayoral election (which may or may not be true), Mitchell begged him not to. Kremlin put the gun to his own head and threatened suicide, and Mitchell used his powers to make the gun fire, killing the closest thing to a father he’d ever known.
