Wyplash is the Skulkin general of Ice, leading the skeletal denizens of the Underworld alongside Samukai, Kruncha, and Nuckal to enforce Lord Garmadon's will. Wyplash was largely absent during Garmadon's takeover of the Underworld, as well as the Skulkin's quest to claim the Golden Weapons. At some point in time, Wyplash escaped the Underworld and was thrown in Kryptarium Prison.
