An Li has a group chat.
The angels in the group all like chatting anonymously and roleplaying, using superhero characters as their anonymous identities.
But one day, she discovers that the angels in her group have all started breaking character.
[Iron Man]: Hah. I have JARVIS, so I can easily make the top three and choose my own anonymous identity, using my own body.
[Winter Soldier]: Bucky, why are you hiding here buying plums?! I've been looking everywhere for you!
[Batman]: Huh? Why am I Bruce Wayne this time, but my anonymous identity is Batman?
[Superman]: So Superman is just a little reporter? Mm-hmm.
[Star-Lord]: I am Grout.
[Apocalypse]: ...Professor, I really want to stab myself right now.
[Magneto]: Calm down, child.
[Apocalypse]: ...I can't calm down anymore QAQ
[Group Owner] An Li: You guys... aren't you breaking character?
The Superheroes: No, we're not breaking character. We've just been forced to use bodies that match our anonymous identities as our secret identities. :)
Hey, thanks to the angels in the group for roleplaying and giving me the inspiration.
In short, you'll show up in the body of whichever superhero you get as your anonymous identity.
The anonymous identity works like a secret identity, but there are some differences.
That's all, over.
