I'm Ann. I don't think I know you, but it's nice to meet you anyway. I have a few characters right now, including one Star wars guy. ;)
Obi-Wan Kenobi: You're probably familiar with him, as is Poe. He crash landed here right after the final fight with Anakin (before he was Vader). He's pretty adamant about getting out of here and assisting in the fight with Padme (who he thinks is still alive). Recently he's teamed up with a couple of other Star Wars characters in this quest. He'd definitely love to hear from Poe about what's going on int he future.
Carol Danvers: She runs Pancho's, the local bar, with Peter B. Parker. She comes here right after the Snap in Infinity War, and lands here instead of Earth after responding to Fury's pager. She's snarky, but always looking to help anyone who needs it. Just please don't destroy the bar.
Miles Morales: From "Into the Spider-verse", he's your typical 16-year-old Spider-Man kid. Miles is getting to know the place and learning more and more about his heroes. He mostly hangs out with Peter B. Parker right now, but he's excited to meet pretty much anyone. And he'll definitely be curious about the whole space thing and light swords.
The Doctor (13): She's trying to figure out what controls this place along with Tony Stark (MCU) and Dr. Strange. She mostly wonders around the town exploring, asking questions, and is excited to find all these new people from different dimensions.
Harley Quinn (DCEU): She's Harley Quinn. Just be careful around here. What more can I say?
Anyway, let me know if you're interested in any plotting or interactions, and welcome! :)
