Agents of Shield: I would love to find a Fitz for my Jemma. The idea would be a season one rewrite and so on, I can give you more details if interested.
Star Wars: I play Jyn and I would love a Cassian in a plot where they survive and fight with the Rebellion.
The Flash: Looking for a Barry to write against my Iris. I'm thinking their version in another earth could be fun, there's a lot to explore there. But canon also works.
