An Unexpected Visit

After Marc wasn't so careful on a recent mission, the Avengers track him down to confront him of his crimes. Turns out he's exactly what they needed and invites him to the crew to stop Loki

I have not read the comics and this will probably be a random au that doesn't fully follow the mcu timeline. Also feel free to correct me on anything I did wrong, this is literally the first fic I've ever made so pls don't be too harsh💔💔
