Hi Cogs! I'm Grace and I've got three kiddos around these parts.
This is Gwen Stacy from Earth-65. She got warped here on her way back through the multiverse and is coming around right around a time where a lot of bad stuff keeps happening and everyone from her world thinks she's bad news. She's got the chops to proclaim the title of Apprentice Sarcastic Asshole Supreme but she's also pretty friendly so, that's why she's an apprentice and not a supreme.
I also have Bucky Barnes the Goat Whisperer from the MCU, and he's coming from just before the battle in Wakanda against Thanos so he's only recently found out he didn't make it out of the fight. He's grumpy and gruff a lot but he's also got a wickedly sarcastic wit so he'll like Strange's humor.
And lastly I have Remus Lupin from the Harry Potter books universe. He's coming from about five-ish months after the First War ended so he's jaded and lonely and depressed but definitely on the mend now that some information has come to light and he's been around his friends again for a while. Being a wizard, he'd be up for being part of the magical support group situation. While he's the voice of reason out of his friends, Remus is also quite mischievous and has a dry wit, so they might get into some banter!
Phew, that was a lot. I hope we get to cross paths in game!
