This story takes place in the Earth-13122 version of the Marvel Universe, which was also briefly seen (and identified as such) in Spider-Man: Across the Spider-Verse (2023).
The special features references to classic LEGO toys, characters and series, including Tuma of the Bionicle franchise. This is not the first time that a Bionicle toy has shown up in the Marvel universe: in the 2008 comic series "Thor: Reign of Blood", the giant creature known as the Blood Colossus was actually two Bionicle models put together, Maxilos with the head of Spinax.
