Worst Hero And Villain War Ever
The palace originally belongs to N Team, where they receive King Charles's message to find and unite the heroes of Videoland. Later on however, Dr. Robotnik successfully conquers it with the help of Ghost Monsters and giant Psycrow, and sets it up as the new base for Videoland Villains. Later Mother Brain uses the Ultimate Warpzone to summon Bowser, an alternate Dr. Wily and Eggman. Villains also use the Ultimate Warpzone to help send Skullmaster to the Sacred Lands of Kaijudo Beasts.
