Rodimus is the name of several fictional characters from the various Transformers universes. He was formerly known as Hot Rod and was first seen in The Transformers: The Movie but was reformatted into Rodimus Prime when he received the Autobot Matrix of Leadership and acted as the movie's main protagonist. Hasbro has used the name Rodimus, Rodimus Major, and Hot Shot as replacements for later characters, due to trademark issues with the name Hot Rod.
