Wanda Maximoff
I’ll be honest: I only want the Scarlet Witch to return in Ironheart because I refuse to believe she’s dead. Once the latest Ironheart trailer revealed Riri will be interacting with and somewhat using the same magical sigils Wanda once wielded, it opened the door (or supernatural portal) for the real major magic players of the MCU to step in.
Riri might find herself in the Dark Dimension, where nefarious cosmic entities like Dormammu reside, and where I suspect the Scarlet Witch might have escaped to. Wanda leading a magically inexperienced Riri out of that evil realm (no doubt for her own nefarious goals), or helping her understand how to imbue her ship with the type of magical powers that can take on foes like Mephisto, would make for excellent reasons to have Elizabeth Olsen return to the MCU.
