ThunderCats - Season 2 Episode 20 Sideswipe

Vultureman creates a weapon that shoots pure Thundrainium in hopes of destroying the Thundercats. His first victims are the Thunderkittens who fall into a deep cavern and become injured. Lion-O and Snarf search for the missing kittens. Meanwhile Vultureman must get more Thundrainium from Chilla in Darkside and is also ordered by Slithe to fix the Mutants' machines. The Thunderkittens are saved by a Wollo and they discover that the Wollo village has been ""iced"" and they are captured and used as bait to lure Lion-O. When Lion-O and Snarf arrive, they are shot down by Vultureman's weapon and Lion-O becomes weak and summons the Thundercats. Just as Vultureman is about to finish off Lion-O, Ben-Gali arrives, wrecks Vultureman's weapon and drives the Mutants and Chilla away. Lion-O then uses the sword to restore the Wollo village.
