The Entity
Super Freak
Theron's playing Clea, Strange's wife in the comics and Dormammu's niece. Seeing as she opens a portal to the Dark Dimension, we'll probably be getting a proper Dormammu in DS3. Maybe they'll make it a Hell Lord/Incursion lead-up type of flick and bring in Chthon, Mephisto and the such too. Honestly, they haven't touched even the surface of Strange lore, so they could make 2 or even 3 more of these, but we know they won't.
At the end of the day, it is just an underwhelming and nonsensical flick that exists as set-up and an epilogue for WandaVision. In a sense it's a worse IM2.
Indeed I saw the Dark Dimension and Dormammu in the portal she conjured up, but I had no idea who she's supposed to be. So I guess she'll have a (big) role in future installments.
What do you guys think? Will we see characters like Krasinski Reed and Cap Carter again, or will they be one time appearances?
