The classic Marvel US & Marvel UK Generation 1 TRANSFORMERS storylines, re-presented together in sequential volumes for the first time ever! Tough, irascible, stubborn, the Dinobots are thrust firmly into the spotlight as their own UK mini-saga ramps up into an epic. Suffering from a neural corrosion condition that regresses them to creatures of pure primal rage, the Dinobots find themselves hunted - by friend and foe alike. Also featured are the UK stories 'Christmas Breaker', 'Crisis of Command' and 'The Icarus Theory', the debut of Jetfire in the continuation of the US storyline, and material created especially for the Definitive G1 Collection, including a look at the UK Christmas story tradition and a new contextual introduction by series editorial consultant Simon Furman. Collecting Transformers UK #41-50 & Transformers US #11-12.
