The Vexos Motherpalace is one of the Vexos' Main Headquarters. It was originally located in Vestal, where it was home to the Royal Family. However, when the Bakugan Battle Brawlers Resistance came back and spread the word about the Bakugan being peaceful, sentient beings, the Vestals revolted against the Royal Family. To escape the riot of thousands of Vestals, the Motherpalace launched into space with the remaining Vexos as well as King Zenoheld and Prince Hydron on board. It Features rigged Bakugan Battlefields that were altered by Professor Clay to the point where only Mechanical Bakugan could win the Battle, along with teleporters.The Teleporters allowed the Vexos to teleport to Earth or Vestal in an instant. Spectra, jammed the Teleporters, so that they could not teleport to Vestal but they were still able to teleport to Earth.
Spectra rammed the Motherpalace with the Vestal Destroyer in Ultimate Weapon. The Alternative was later launched from the Motherpalace but because of the Alternative's huge size the Motherpalace was destroyed for good.
