Twitch, known in *League of Legends* as the Plague Rat, is a sewer rodent that mutated in the depths of Zaun following continuous exposure to the toxic chemical waste of the Undercity. This toxic stew not only dramatically increased his size and granted him bipedalism, but also gave him sapient intelligence, speech, and an obsessive devotion to filth and decomposing garbage. Armed with a crude crossbow loaded with bolts soaked in corrosive chem-tech venom, Twitch stalks the Sump driven by a deep paranoia and the oversized pride of protecting his junk "treasures," turning into a legendary and grotesque figure who personifies the extent to which Zaunite pollution can engender life.
