Super Smash Bros. Melee/Movelists/Kirby

Throws
Kirby's Grab is very short range, but it's lightning quick, making it easy to use while dashing past an opponent.

Suicide Swallow
Swallow someone then jump off the ledge (which would leave a long time for the swallowee to escape). A much better way to do this is when an opponent is right on a ledge, jump off the edge and on your way down, inhale them.

Super-Invincibility
Jump and use Kirby's Stone (Down + B). When Kirby falls, he will be invincible for a short period, at which point no enemy can touch him, and he can easily detonate Motion-Sensor Bombs/Bob-bombs or trigger Flippers without being hurt. He is vulnerable to grabs, though.

Suicide Throw
If used near the edge, Kirby's forward throw brings both fighters down. The fighter who is grabbed will hit the bottom first. Keep in mind, if the grabee breaks free during the front flip, Kirby will dive to his death alone.
