You can't play as Tabbu. No way no how.
However, you can fight him in Boss Battles (recieved after beating Subspace Adventure)
Can you play as Tabbu in Super Smash Bros. Brawl?
maybe with homebrew.
No only if you hack.
It's not possible to unlock him in the brawl game and play as him whenever you want. you can't play as any other bosses either Iqskirby
you go to the area with all the trophies in the background & it's all subspacey. then go to the middle to meet tabbu, the final boss

Tabuu is the final opponent faced on Super Smash Bros Brawl. You can fight Tabuu after defeating all previous foes in the Great Maze stage of the Subspace Emissary, he is in the center of the maze. He is incredibly hard to beat, so be prepared for a fight.
What you need to do is beat Tabbu and then after that get Wolf, Toon link and Jiggly puff. To get 100% you need to get as many trophies as you can. Get trophies from those blue and yellow boxes or turn your enemies into trophies.

In the great maze after you beat all the bad guys there is a door somewhere and then it takes you to tabbu there you get sonic and you get to choose 5 or 6 characters but choose wisley he is hard as hell I got down to my last guy pit and just beat him with an arrow hoped this helped #.

In The Great Maze, go to either The Battlefeild Fortress or The Swamp. When you see a purple arrow pointing to a door, go through it. If you don't see any trophies there, go through the gate (how you would usually go through regular doors). After a cutscene with Tabbu and Sonic, select 6 characters (Sonic will now be available to play in the Subspace Emmisary) to battle Tabbu.
No he isn't, he would be way to powerful, not to mention he isn't even from a Nintendo franchise.
