Yea one move can really improve a character. If you gave kirby lasers from the start that he kept, he could camp extremely well. Also being able to duck underneath a bunch of the powershielded lasers.
kirby may actually move pretty significantly because of a **** projectile.
That's almost as logical as me giving Captain Falcon a projectile that launches scatter shot Falcon Punches which give out the same damage input and knock-back on every hit.
It's only logical, my lad.
