He returned in Wiseman Cometh and Enemy Allies only to be taken down by Dragonoid Destroyer and the Brawlers each time. Another loss is gained, this time against Duomechtra, much later in The Eve of Extermination.
Mechtavius Destroyer finally overpowered Dragonoid Destroyer in Countdown to Doomsday.
In Evil vs. Evil, he fought Gunz and the Nonets. Overwhelming the Nonets without difficulty, he managed to kill and absorb most of them with the exception of Betadron and Worton. Mechtavius Destroyer grew massively in size as a result of his destruction.
In Beginning of the End, he fought against the Brawlers and their Bakugan once again.
In End of the Line, he fought Dragonoid Destroyer one-on-one, but was obliterated by him. Because he was destroyed before he can complete his plans, the future Mechtavius Destroyer was erased from the future.
