Super Smash Bros. Melee/Young Link

Wall Grapple
When using Link, Young Link, or Samus, pressing Z or A+L or A+R to use the character's hookshot (Link and Young Link) or grappling beam (Samus). This can be done during the aforementioned characters' air dodges. It can connect to most solid ledges or walls and will allow the character to hang there; pressing A reels the character back up towards the stage. A triple jump attack (Up+B) can be performed immediately afterwards. The air dodge can be used to position the character properly before using this recovery technique, since the hookshot/grappling beam will not connect if the character is too close or far from a wall. If it hits an enemy it does some damage and has minimal knockback.

In general, this move is superior to the Up+B for recovery, except in stages like DK 64 where it won't work.

Bomb Jump
Young Link also has the ability to bomb jump, but it is not quite as effective and much more difficult to pull off. Basically once you’re off the edge (from being hit), pull a bomb out, throw it, and proceed to jump and up B, if you do it correctly then the bomb will blow up on you and you will be able to perform another up B move.

Auto Block
Young Link automatically blocks projectiles with his shield just by standing there, granted they're at the right height, of course. Ducking will also accomplish the same thing. Samus’ Charge Shot, Bob-ombs, almost anything. Young Link can't use this ability while holding items (Since he holds them with his right hand and puts his shield on his back). Unlike Link, Young Link will lower his guard during his standing animation.

Boomerang hookshot glitch
In 1.0, it is possible to throw a boomerang and hookshot a ledge. When the boomerang comes back Young Link will shoot up impossibly high into the air. This glitch is fixed in later versions (Player's Choice, PAL/European)
