The 2002 MYP MOTU reboot was the most serialised MOTU cartoon ever produced. Showrunner Larry DiTillio (Filmation MOTU veteran, Babylon 5 alumnus) built the show around a season-long arc that the original Filmation series — beholden to syndication’s any-episode-can-air-anytime constraint — could never have attempted.
Season 2’s central plot was the Snake Men’s return. The Snake Men, an ancient evil sealed away by the Council of Elders eons ago, begin to break their seal. The plot reframed the He-Man / Skeletor confrontation as a subplot of the larger threat: both factions face annihilation if the Snake Men fully escape. Skeletor’s reluctant alliance with the Heroic Warriors against the larger evil is the dramatic engine of the season.
Cartoon Network cancelled the show after Season 2’s 13 episodes. The Snake Men arc was left mid-resolution. The finale (titled “History”) delivers the canonical Keldor / Randor backstory but cannot resolve the Snake Men crisis. DiTillio had planned a third season; concept art and writers’ room outlines for that season have surfaced piecemeal in collector communities over the past two decades.
The Snake Men arc’s narrative legacy is preserved in the modern continuities. Revolution (2024) revisits the Snake Men in its later episodes. The Origins toy line has produced complete Snake Men waves. King Hsss, who never finished his MYP arc on screen, has appeared in nearly every MOTU continuity since.
