In the 925th Universe, Super Besties: Assemble was a movie owned by Dibbsy, sponsored by the real Super Besties Justice Squad. It introduced the character of General Loki. (PROSE: A Series of Queer Events)
Behind the scenes
This film appears to be an analogue for the 2012 Avengers film, with the title evoking the titular Marvel group's catchphrase, “Avengers: assemble”. Although the Marvel version of Loki did act as the film's main antagonist, this was not actually his introduction.
