Zen Buu JUS

Having inherited Vegeta’s drive to defeat Goku, Super Buu moves him away from the organ wherein he kept the other Fighters absorbed, and challenges him to one final battle. Left alone against the monster, Goku attempts to stop Super Buu by transforming into Super Saiyan 3 and battling him inside of his body, though he is quickly outmatched, and eventually reverts to his base form after a desperate last-ditch against Buu, from which he easily regenerated from, before ultimately absorbing Goku, leaving the future of the Earth seemingly hopeless.
