In-Game: Link's younger incarnation is often considered to be the true Link; he was a young boy in the very first Legend of Zelda game, and he has appeared as a youth in most of the subsequent games. Since his debut on the original NES in 1987, Link's appearance has changed over and over again, each time adding to the mystique of his incomparable story.
Smash: Young Link is lighter and faster than his older self, and his Kokiri sword packs less punch. Even though his Boomerang has a shorter range, he has greater control over it. He's a smaller target, and while his Hookshot has less reach than the older Link's, you can still use it in midair as a last-ditch attempt to grab a ledge.
All Star: With a youthful spring in his step, Young Link can perform amazing wall-jumps. Once he hits a wall, tap the Control Stick in the opposite direction to send him leaping upward; you can practice to your heart's content in Target Test. His Spin Attack can strike multiple times even on the ground, and although it's hard to discern, so do his Bombs.
Fire Bow: [B] Works the same way as older Link's bow, but the arrows are charged with fire, making their attack stronger.
Boomerang: [over + B] Works the same way as older Link's boomerang, but flies shorter distances.
Spin Attack: [up + B] Works the same way as older Link's attack, but hits the enemy multiple times.
Bomb: [down + B] Uh...works the same way as older Link's bombs.
Hookshot: [Z] You guessed it. Works the same way as older Link's hookshot, but covers less distance, so you'll have to stand closer to pick someone up.
Takes a gulp of milk, then gives an "Ah!" Intimidating.
Great Bay: A stage set near the laboratory in Termina. A giant turtle pops in and out of the water. Either Saria's Song or the Zelda theme is played on this stage.
Booklet: A sword-wielding hero who also boasts long-range attacks.
In-Game: Even in his youth, Link was already becoming the warrior who would carry the destiny of Hyrule (and many other lands) on his shoulders. His epic struggles against the forces of darkness are written in legend, and he is bound to the Princess Zelda and the archfiend Ganondorf by the awesome power of the Triforce.
Smash: Burdened with a shield, a heavy sword, and plenty of equipment, Link is not a very mobile character. Nevertheless, he's skilled with the blade and his varied supply of missile weapons makes him a powerful fighter. To master Link, you must control the pace by balancing your long-range attacks with head-to-head swordplay.
All Star: Link's Bow, Boomerang, and Bombs all take time to wield, so you may want to try drawing them in midair to prevent your foes from attacking you while you're vulnerable. The Spin Attack can score consecutive midair hits, and the final slash is very powerful. Link's Bombs are his trump card, but he can't pull one out if he's carrying another item.
Bow: [B] The longer you charge Link's bow, the farther the arrow will fly and the more damage it will do.
Boomerang: [over + B] You can change the course of the boomerang by tilting the control stick. Link must wait until the boomerang comes back to him or flies off screen to shoot it again.
Spin Attack: [up + B] My favorite attack. *evil grin* The spin attack has a fairly wide range and the ending blow hits the hardest (good to send people flying). If used in the air, it lifts Link higher.
Bomb: [down + B] Explodes on impact. Just make sure you're away from the competiton when you throw it, because if you're stunned, the bomb will blow up with you holding it. o.O;
Hookshot: [Z] Used for throwing enemies. Once the opponent is close enough, you can either hit them a couple times and/or throw them in any of the four directions. Funness!
Brushes his hair back with his hand.
Hyrule Temple: A huge castle-like stage floating in the clouds. Either the temple theme from Zelda or the Fire Emblem theme is played on this stage.
