Devil Dinosaur

In Marvel continuity Devil Dinosaur is a young dinosaur native to Dinosaur World. According to published biographies, he was nearly burned by a tribe called the Killer-Folk; exposure to the Killer-Folk's fire "activated a mutation in the dinosaur which gave him powers greater than others of his species and turned his skin red," after which he was rescued by Moon-Boy and became his inseparable companion. His setting is an alternate prehistoric Earth where dinosaurs and primitive humanoid tribes coexist.

Depicted as an enormous, crimson, Tyrannosaurus-like dinosaur. Sources emphasize his large size and red/crimson skin coloration, the latter described as the result of the mutation triggered by exposure to Killer-Folk fire.

Sources state that exposure to the Killer-Folk's fire "activated a mutation in the dinosaur which gave him powers greater than others of his species" and that he has exhibited superior physical power and resilience compared to other dinosaurs. Narrative incidents document his ability to participate in cross-universal adventures (being transported to Earth-616 and other locales) and powerful physical force (for example, accidentally killing the Fallen Angels' member Don by stepping on him). Specific supernatural powers beyond the mutation, and detailed limits, are not enumerated in the supplied sources.
