 * Grimlock is a guest character in Marvel's Spider-Man: Webbed Champion, voiced by Travis Willingham. He appears in the crossover arc "Legendary Universes" alongside his fellow Dinobots. Officially appearing in "Legendary Universes, Part 4: Heroes in Disguise", he and the Autobots help Spider-Man's team defeat Megatron and his Decepticon faction and Predaking's Kree Armada and solve the origins of Arsenal's robot body. During the episode, he forms a very close friendship with Speed and Ant-Girl, as Spider-Man remarks that Grimlock is "fulfilling children's classic dream of seeing a dinosaur". Grimlock and his fellow Dinobots later appear in "Part 6: Ultimate Alliance", where they join the final battle against the Regent and his army from the Negative Zone.
