Ionic energy from what I recall. He has control over ionically <--(Not a real word lol) charged beings. Blue Marvel beats him, just like Anti-Man would beat him.
BM was playing "Odd Couple" with the Watcher for too long.
He needs to hit the gym, get a haircut, lose that belly (evidently his wife, the Watcher, is a good cook) and do a few publicity adventures with clowns like Hulk, Wolverine or Sentry. Maybe a buddy-story with Thanos.
That way, he can start building some street cred.
Dambo's rage is boiling over. He's the biggest fan of Blue Marvel in the world, and he did all he could, but it just wasn't enough to trick people into thinking he's a class A tuffy.
Never let anyone else define you. Don't be a jerk just to be a jerk, but if you are expressing your true inner feelings and beliefs, or at least trying to express that inner child, and everyone gets pissed off about it, never NEVER apologize for it. Let them think what they want, let them define you in their narrow little minds while they suppress every last piece of them just to keep a friend that never liked them for themselves in the first place.
