tabuu is the final boss in ssbb  his plan was to cut the world of trophies into pieces and make the great maze  he
created the subspace army out of mr game and watch because he cant leave subspace and also got bowser wario ganondorf and r.o.b to join


when tabuu was seen with the chains of light on master hand he used 5 chains it may be possible that tabuu has more than one of the chain of light
