Beyond Good. Beyond Evil. Beyond our Theme
The Transformers: The Movie isn't considered canon on the Transformers Universe MUX. However, most the other prominent characters from the movie have been added to the theme, largely as they were at the start of the film, with the assumption that the events of the movie never happened. Hot Rod is still a turbo-revvin' young punk, and the arrival of Unicron was handled differently on the MUX.
Because the events of the movie never happened on the MUX, certain things are different in our theme.
