called you out a bunch today
needed some comic expertise on who Clea goes with besides Dr.Strange cannonicaly
She was a member of the most recent Defenders team lead by Valkyrie, but the only one of that crew who's in-game so far is Misty Knight, herself as a Luke Cage summon iirc, and Luke Cage did serve on the original Defenders team for a brief period of time before he quit.
The old Defenders were kinda weird in that they didn't have a set roster, but she was an occasional member, so she could work alongside Hulk, Silver Surfer and Daredevil on the note of their teamwork there. Antman, Beast, Black Cat, Black Panther, Hawkeye, Iceman, Iron Fist, Moon Knight, and She Hulk have all been members too, but not necessarily at the same time as Clea. There have been times when everyone who's ever been a Defender ever has been called together though, so I guess it depends on how far you're willing to stretch that association.
She used to get paired up a lot with Scarlet Witch in various group shots and poster books and stuff from back when she was relevant- I don't think they ever had any actual friendship or notable interaction outside of that, but those swimsuit specials are totally canon no matter what anyone else tries to tell you, so make of that what you will.
Clea didn't show up too often outside of Strange's books, and Strange's books didn't connect to the usual capestuff too much- then she stopped being relevant altogether when it was decided that Strange needed to be retconned into a womanizing sex addict, and his wife had to be quietly swept under the rug to let the change happen. I was hoping Bunn would do something interesting with her, but then Fearless Defenders got canceled, and I don't think she's been mentioned anywhere since, so not many opportunities for interacting with the Marvel universe proper.
Hope that helps, sorry for not seeing the request in-game.
