IDW’s Teenage Mutant Ninja Turtles comics synthesize and remix 40 years of Turtles’ lore and transform it into a single sprawling epic! This sourcebook collects and catalogs every character, every location, and every notable event—and serves as a comprehensive companion to that epic—into four issues by writer Patrick Ehlers. When the mutagen bomb goes off, the wall goes up and shell breaks loose! The Teenage Mutant Ninja Turtles join throngs of new mutants and try to live normal lives in an extremely strange place. Issue #4 of TMNT: Sourcebook takes a tour of Mutant Town and explores how society reinvents itself in the wake of a paradigm shift. Men become beasts, friends become strangers, and enemies…become bandmates. Go inside the Splinter Clan’s efforts to protect Mutant Town from humans, aliens, gods, and even from itself.
