General Zythion was a Koopa general. He was the leader of the Koopa army before Bowser.
General Zythion lived during a time where there were no kings; only generals. He fought and conquered many territories, but fought about the future of his people. He then decided to give the Koopa Jewel, the symbolism of leadership, to a child who would become the king of the Koopas after Zythion's death. A Magikoopa informed Zythion of a child who would be special enough: Bowser. Zythion then entrusted the jewel to the young Bowser.
- As Zythion conquered many lands during his reign, it is possible he built the castles and towers seen throughout the New Super Mario Bros. series (And the original games).
