Fan Casting Master Core in Sm4sh

He is thought to be another celestial being that wants to eradicate life. But plot twist, it is the final form of an old enemy. Now with the essence of Tabuu, Giga Bowser and Ganondorf's energy combined into one, he is the most powerful and nearly-invincible being on the planet. His name may be Master Core, but when mysteries about him were solved, he had another name. The old enemy that brought the Smash fighters together: Master Hand! His old goals are gone. But now he just wants to have revenge on Mario, Sonic, and the Smash fighters (old and new)!
