Bel has whatever powers the writers want him to have that week, sigh.

"Flaming Balls of Death"/fireballs/energy balls: they can kill/vaporize outright or just burn/propel victim into a wall or, at low power, stun or sting.

Shimmering: teleporting from place to place. No limitation is given in canon, but I've said numerous times that he can take one passenger with no problem, two he can generally manage okay, three is pushing it and weakens him. He can go between dimensions easily and distance doesn't seem to be much of a factor.

Telekinesis
Transmutation
Shape-shifting
Slow time
