As soon as the fight starts whats to stop Franklin from just crushing everything around him? His first appearance that's the first thing he did, just pinned everybody to the ground.
And if Mirror Master gets to start off in his Mirror World, Graviton should be able to start with his forcefield up, flying, and already increasing gravity.

Or his shiny metal costume. Can't MM float from one reflective surface to the other without teleporting out?
His costumes were never shiny save perhaps on some depictions of the red dots/plates which is inconsistent at most (writers depict them as plain dots or sometimes glowing).
I'm not sure about the floating between reflective surfaces though but that won't do him any favor unless he teleports to the real to use his actual deadlier options.
