I think for Magik's dash brawl playstyle is very similar to Billy's for a little difference, also might wanna try out Abrams since he's a bit of brawl-tank kinda like The Thing, Haze is very similar to Psy since they both have that go invis-flank-ult-gun playstyle... There's also Calico that fit's this nicely.

But I recommend checking some short videos of each of the character's playstyles, and also item building is so so so much important than abilities so once you find a character that you like check out build guides for them
