On the Sacred World of the Kai, Xeno Goku battles against Xeno Majin Buu who had merged with the Three-Star Dark Dragon Ball when the Dark Empire forces arrive being led by the Demon God Dabura who intervenes in their battle and slices Buu in half. However whilst Dabura is focused on Goku, Buu regenerates and absorbs Dabura whilst he is off guard. Having absorbed the power of a Demon God, Buu's power soars and he eradicates the entire Dark Empire fleet.
He turns his attention to Goku and immediately overwhelms him, only being saved at the last second by the sudden appearance of Xeno Trunks who had arrived along with backup. After Goku: Xeno and Xeno Vegeta fuse to become Xeno Vegito, Buu fights against the fused Saiyans in an evenly contested fight until Chamel appears in the middle of their battle and soon after Buu escapes through a space time rift.

Buu reappears in Hell during the ongoing commotion between Xeno Goku, Xeno Vegeta and Chamel and their battle against Towa and Shroom for possession of the Five-Star Dark Dragon Ball.

Buu makes a last appearance during the battle between the Time Patrol and Xeno Slug and Towa. Buu suddenly appears by attacking Slug with his sword, sending it in and out of many different rifts, cutting away at his body.

In Super Dragon Ball Heroes: Dark Demon Realm Mission!, Xeno Majin Buu with the Three-Star Dark Dragon Ball merged is shown to be able to outmatch base Xeno Goku - with the Saiyan being heavily damaged while Buu is unhurt, Buu is also shown to be largely inferior to Demon God Dabura who quickly defeats him, however upon absorbing Dabura and his Demon God power, his strength increases to a point that he is able to fight on par with Super Saiyan Xeno Trunks in a brief sword duel (even after being taken off guard) and then after ditching his sword proceeds to fight on par with base Xeno Vegito. However, Dark Demon God Buu is completely outmatched by base Chamel, even after using his strongest attack. Later on, after having also absorbed Xeno Janemba, his strength increases once more, but he is later easily defeated by Demon God Salsa after his power has fully stabilized.
