@TyranitarKid His speed is already a melee range speed, faster than normal. For those who don't know, base speed is given to brawlers (disregarding star powers) as Normal Speed, Melee, or Assassin. Normal is most brawlers, Melee is Bull, Primo, Rosa, etc. Assassin is Leon, Crow, Mortis.
Sounds like you keep getting killed while trying to attack enemy brawlers head-on. He's meant to be in bushes, his range doesn't matter.
