Fan Casting Legion in Robert Smigel's Green Lantern

An enormous, yellow robotic monster that is actually the collective consciousness of all Tchk-Tchkii enmassed as one. Legion is ancient, powerful, and utterly vengeful—it was defeated and contained by the Corps millennia ago but has now returned to seek revenge. Its booming, layered voice speaks with the authority of a thousand beings. In a bizarre twist, Legion takes the form of a giant Pikachu to distract Earth—revealing that even cosmic horrors have a sense of twisted humor.
