both kirby and ike share the same up b in ways but the thing that kirby has is definitely an aerial advantage
the thing for ike is it is more of an attack than a recover, although many a time it is definitely a liable way to get back up
i think ike's side b is a better way to recover since i find more often that ike's flung to the sky than to the floor
but yes his recovery options and susceptibility to projectiles makes him a plongerdonger but i still find it fun when you are able to time his powerful moves correctly with his slow tempo
i hope in this new one they are able to change it up a bit
even though i did state he does definitely look like a heavy character (now more than ever) he's able to hold the ragnell ingame with ease so i'd hope maybe he could move slow but his attacks would allow for better maneuvering about
and maybe his up b could be so then if you quickly tap it he'll float more in the air, but if you hold b and charge it, then let go, its faster, more powerful, but harder to control
