[Phantasm]

Strange would probably get along with both Fate and Zatanna, and may even offer Zatanna some additional training. It's little known, but Zatanna's mother was a member of the Homo magi, a magical offshoot of humanity, so she can (and has in the past) use traditional magic as well as the "speaking backwards" magic she and her father (and cousin, of the One Year Gap Teen Titans) are famous for. Also, I can see Clea (Strange's apprentice/wife and Dormammu's niece) and Zatanna interacting socially.

Fate's own magic is different enough from Strange's that the two may or may not be compatible.


Of the Marvel magical characters, I can see Constantine interacting most with Hellstorm and Ghost Rider, and possibly with Jack Russell/Werewolf. Jack's teenage sister Lissa (cured of being a werewolf, but has been kidnapped a dozen times, transformed into a non-werewolf form several times, and possessed twice, once by Morgan Le Fey - definitely some "Damsel in Distress Weirdness Magnet" trait going on there) has some magic potential, thanks to the family's ties to the Darkhold.

I can kinda see Constantine working with Devil-Slayer, Hellstorm, Hellcat, Nighthawk, Valkyrie, Gargoyle, and the rest of that lineup of Defenders, though they'd probably have to ditch Strange, Namor, and the Surfer to get it to work. If nothing else, he'd be the guy the heroes would turn to when they had some mystical threat that required more subtlety than Dr. Strange - or the guy who would gather a bunch of low-level occult heroes together for a job or three.
