The next expansion needs to be about Tataru's eye getting scratched by Fat Cat, then she wears an eyepatch and forms Eorzea's Avengers Initiative! I haven't got it all worked out yet, but so far I have...

Aymeric: Captain Aymerica
Cid: Ironworks Man (with magitek power suit that has Nero as its AI interface voice)
Estinien: Hawtguy
Alisaie: Scarlet B*tch

Alphinaud would sort of be a Tom Holland Spiderman type, but with an "Iron Spider" style suit where his Sage nouliths are the four pointy bits and they shoot healing webs, maybe? Raubahn would totally be Hulk. Thancred and Y'shtola would be the "Black Widow" and "Dr. Strange" of the group, respectively. Uh, I just realized I forgot all about Thor. I was gonna say Gaia somehow, if only because she has a hammer. But you know what, no -- Hildibrand will be Thor, thus making Godbert into Odin. That seems cool.

I don't know who Ant Man would be, but the shrinking tech needs to have a side quest where you harvest Gastric Orbs from Cerberus's room in World of Darkness.
