The Offspring of Zorc were the main antagonists of Super Smash Bros. Crossover. The name of the group comes from the fact that the members are the offspring of Zorc Necrophades. The full group debuts in The Keys of Smash Arc. The Offspring of Zorc consist of Yami Bakura, Yami Zelda, Yami Kirby, and Zombie Reed. At the end of the first arc of Season 21, Samus becomes a part of the Smash Core and Mutant Elfin leaves the group to rejoin the heroes. In Season 22, Bowser defects from the group because of his tragic and complicated past. In Season 23, Samus realizes the error of her ways and rejoins the Heroes of Legend. Later, it is revealed that the Offspring of Zorc are connected to the Heroes of Legend, and later join the Heroes of Legend, with Coredegon replacing them as the main antagonist of the series. However, Mechtavius Destroyer tempts the Offspring of Zorc to abandon their friends, which they willingly agree to do.
