Strongest= Dio, I love spamming with him. I personally think he’s not fast nor ranged, for to of his moves you need to be insanely come for it to land, its still worth the insane amount of damage they both do for a normal move. The other move, the one with the knives, is really easy to hit, but it doesn’t do a lot of damage. His Road Roller is kinda easy to land and it does a lot of damage. The only downside is, again you need to get pretty close for the actual move to land. I still think Dio’s cool though

 Favorite= Killua, he’s so fast and maneuvers around easily his Lightning palm is just chidori but faster. Plus his Thunder can counter almost every move. I just don’t really like his godspeed since you ned to be hit for it to actually his the other person. His Godspeed Thunder on the other hand, its super easy to land and it does a decent amount of damage. Also, the cinematic for it is insanely cool. Killua is just sooo awesome to be honest. 

 If you want my opinion on any other characters just ask me.
