Leo follows Triskull and the Ghouls from Mirinoi (through a wormhole between planets), to Mariner Bay on Earth. Seems Triskull is working for Olympius, collecting humans to drain them of their lifeforce. But little does the demon prince know, that Triskull is ALSO working for Trakeena, who plans to use the lifeforce to return herself to her mutated form. Leo runs into the Lightspeed Rangers, and soon, his teammates Kai & Maya follow, all teaming up. A young girl, Heather, alerts Carter to her mother's kidnapping, which leads the teams to Triskull's human-snatching cover at a bank.
