The Chaos Pack
The Chaos Pack was a group of 3 Mutants made as examples in a White Dwarf article. These three mutants were Zygor Snake-Arms the mutant Night Goblin, Leaping Slomm Two-Face the extra-mutated Chaos Troll, and Ngaaranh the Chaos Spawn, who used to be a Harpy and is still somewhat recognizable as having originated as one. As for who they worship/follow/pledge allegiance to, only Ngaaranh is listed as having a god they're dedicated to, a Minor Chaos God by the name of Kka. The 3 of them (maybe 6? Ngaaranh has 3 heads and Slomm 2, and it's unknown if either of these heads have minds/souls/wills of their own) wouldn't be out of place in a late 1980's/early 1990's Warhammer Fantasy cartoon with them as the recurring antagonists in the style of Scratch, Grounder, and Coconuts from "The Adventures of Sonic the Hedgehog" or Bebop and Rocksteady from "Teenage Mutant Ninja Turtles", being a gang of moronic baddies serving Kka the Minor Chaos God as his 3 only followers.
