In this troper's fanfiction, he tends to refference things from different universe's or adaptions of the thing he wrote about. As well as refferencing his other fanfiction. Like, in one of the earlier chapters of my XMenEvolution story, I make refference to using the Danger Room to play Crash Bandicoot (Which I was previously known to write about) and when Spidey first guest starred, he makes refference to planning out what he will write in his own Crash Bandicoot Fanfiction. And in one chapter, Iceman gives Shadowcat a wedgie, which was intended as a nod because me and several other Crash Bandicoot writers were doing an online RP that degenerated from an undecided plot involving Dr Cortex into Nina Cortex giving everyone in the world wedgies. As for refferences to other universes and adaptions, I tend to name background mutants after ones from the comics, and when they read the blog for a school bully, they act shocked by his listed dislikes of inculding 'Hugh Jackman', to who they insist is a national treasure. One of Taskmaster's first lines when he appears is to tell Bullseye, who just destroyed his mask to reveal his facial disfigurment,
"You are the Ass kick-ee, I am the Ass kick-er!" Later in the same arc, Norman Osborn, who is yet to don thr Goblin suit in my universe, looks at his reflection on a billboard, causing his skin to look green and make him look like a Goblin. The Transformers guest star in my second 'Evo Team ups' story, a Nod to my previous attempt to write a Transformers fanfiction that would have been in the same universe. And lastly, many costume designs for new characters are moddelled after what they wore in XMenLegends.
