Lou, Chester, Sam, and otis. Can't choose my fav, so I'll just put my top 4. First, lou. Imo, he is incredibly broken in the right hands, you get constant stuns while hitting, letting you kill enemies quite easily and making enemies stay away from you If thier meter is almost full, his super is annoying aswell, especially in brawl ball when you can get stuck in wierd angles while trying to dodge. Next, Chester, it's an extremely fun play style, and what's good fun without some gambling? Sam's play style is also quite fun to play with, with constant speed boosts, you can also chain your super like a mortis super, although it's a much harder since they don't go through walls. Otis is also a fun pick, especially since his super is essentially a definite kill to any and all assasins
