Reborn Evil - Birth of Dark King Fu!

Fu is horrified by the Universe Tree's death, until Towa and Mira arrive to help him. Towa infuses Mechikabura's energy into Fu, dramatically increasing his power and causing him to undergo a transformation into the new Demon King. However, Fu expresses no interest in this, and begins using his new powers to restore the Tree instead. Vegito tries to stop him and their fight resumes, but Towa and Mira intervene to help Fu and buy time for him by attacking Vegito. Before Fu can finish restoring the Tree, however, a portal opens and Xeno Vegito emerges, now powered up to Full-Power Super Saiyan 4 and accompanied by the Demon God Demigra. Xeno Vegito attacks Fu, and the battle resumes. Meanwhile, in an unknown location, an alternate version of Broly awakens.
