Loki’s Chitauri invasion of New York takes place at night, rather than during the day, so when the Avengers have to stop him the Gargoyles wake up and are like “what the fuck is this shit even, we were looking forward to beating up the same three muggers we always do.” So they team up with the Avengers and stop Loki, and afterward one of the Power Trio - probably Lexington, he’s the most technologically savvy - actually *joins the Avengers.*
Of course, Xanatos turns out to be one of the primary backers of SHIELD. He and Nick Fury have beer-and-pool nights where they talk about their various ridiculously convoluted schemes.
And when Tony decides that he needs an AI for the Iron Legion, Lexington just tells him, oh, I know where you can get one. Goliath met one in Australia. No need for any of this bullshit with Loki’s scepter.
The second Avengers film would, instead of what we got, be about the team having to thwart one of Demona’s schemes to kill all humans with weird magic.
I’ll never write any of this, but it keeps me warm at night.
