10 Invincible Moments That Shocked The World
9. Mark Fights Allen
Perhaps one of the most surprising fights of the entire series is the first between Allen - a defender of the galaxy - and Invincible, who had only recently become a superhero at this point in time.
However, Mark discovers that this new alien enemy isn't as he initially appears very quickly. Allen reveals that he's actually sent to planets in the Coalition every free years to check that their guardian hero is up to standard. Which is why he's been sent to Earth - only, he hasn't been, as when he checks his rota he awkwardly discovers he is instead supposed to be at Urath, and has confused the two planets.
After an awkward apology, Allen darts off to the planet he's actually supposed to be at, thanking Mark profusely for giving him the head's up. And so, hilariously, the two begin a life-long freindship, that would have never happened had they not tried to murder one another.
