Commander of the Spartan Army, Leonidas led thousands of battles. Men, Demons, Gods, they've all been crushed under his swords and fury. There is a myth telling Urban invoked the Legendary demigod of War from hell to rule over the tournament, promising him to bring his wife back from the dead as well as immortality.
- Inspired by King Leonidas of Sparta.
- May also have been inspired by Kratos and Deimos from the God of War video game franchise, due to this Mutant looks like fusion between Kratos and Deimos and his chains and swords which Kratos and Deimos also wields. The Platinum version also strongly resembles Kratos.
- His Gold version resembles Drax from Marvel comic and franchise
- It was first seen in the Miami Beach Clash PvE event.
- His Necro attack "Ghosts from Sparta" maybe a reference to Kratos' alias "The Ghost of Sparta".
