The incarnation of Link in The Legend of Zelda: The Wind Waker appears as the replacement of the younger version of Link in Super Smash Bros. Brawl.
I loved The Wind Waker so I was really happy to see Toon Link in Brawl. He wasn't much different from Adult Link but for a clone character he was at least visually much different.
So I used him a lot since Link is always a great character.
His Final Smash Triforce Slash is the same as regular Link. Pretty awesome attack, though it only targets one opponent.
