Ultra Magnus did not appear in Marvel Comics' American "Transformers" comic book series outside of a comic book adaptation of a third-season episode of the animated "Transformers" series. However, its sister title in the U.K. "did" feature in the character extensively in its own original stories (particularly issues in and around the 100 mark); the American stories made no use of the new cast introduced in "", and U.K. writer Simon Furman pounced on the opportunity to use them in his own ways. Whereas all the other movie characters who appeared in the stories — such as Galvatron, Hot Rod and Kup — appeared via the use of time travel, it was Ultra Magnus's present-day self who played a key role in many of the important UK storylines. As per the original intent of his character and toy, Magnus was presented as the arch-foe of Galvatron.
