The powerful Retak'ka was too much for BoBoiBoy and the gang to handle. He had unleashed hell upon Earth and ravaged anyone that dares cross his path. BoBoiBoy, defeated by the hands of the armoured alien, used his ultimate Elemental Split as a last resort in hopes of defeating Retak'ka. Equally matching the fight, they have both prepared their final blow to completely finish off each other, resulting in a blinding blast that consumed them whole. BoBoiBoy thought everything was over. He had saved the whole galaxy from descending into hell. He is now free. Until he woke up, in a train, vaguely familiar to him. His body is what of a 10-year-old would have. Holding a soccer ball in his arm and a luggage sitting in front of him. He is now in the past. ~~~~~~~~~~~~~~~~ BoBoiBoy Galaxy and the characters are owned by Monsta.
