A Bioshock Infinite / SNK crossover. It’s a messy bunch of spoilers if you haven’t played the game or read the manga, ahah!
Titan!Eren as the Songbird. Erwin and “fem!Erwin” as the Luteces. Mikasa as Elizabeth. Levi as Booker (I used a cosplay photo as a ref but I can’t find the cosplayer. If you recognize yourself here, just contact me and I’ll credit you!). Explanations about the characters here. Lot of spoilers.

More BSI/SNK to come..?

… It’s a matter of constant and variables.
