The first thing you should do before fighting Tabbu, is to assign Heavier characters, or characters with good range.

Suggested Characters:





-Meta Knight

-King Dedede

-Donkey Kong



When Tabbu Moves to one side of the stage, move away from him. Time your jumps to dodge his Projectiles. Whenever he Executes a shot range attack, hit him with a projectile of your own while he's vulnerable. 

When Tabbu jumps behind you and sprouts his wings, immediately move to the end of the stage. Roll or side-step the Off-Waves when he fires them.
