With the Disney/Fox Merger, Marvel Studios has finally regained the rights of characters like the X-Men and Fantastic Four. Though we know they're coming to the MCU, we don't really know how. What's interesting is, it's possible that MCU canon is already planting seeds for the dawn of homo superior.
ScreenRant speculates that this passage from the book The Wakanda Files hints that Wanda and Pietro Maximoff already had dormant powers and were just enhanced by being exposed to an Infinity Stone. Here's the passage:
"The Stone similarly transformed her nervous system, but it has ionized and charged it in ways that have given her an extraordinary ability. Neural-electric interfacing allows her to create bursts of extreme energy using only her mind and the tips of her fingers. The manipulation of this energy permits her short bursts of levitation, in addition to a staggering weapon that only requires her bare hands.
What is beguiling is how Wanda's nervous system has also unlocked potential for telekinesis. These are not parlor tricks; she is not just bending spoons. She can manipulate minds and plant suggestive thoughts, even enhance preexisting paranoias. She can see into the mind of a human, find out what they fear and what will motivate them."
While they didn't really say anything like "mutant" I guess it would pass for a small tease moving forward. Though Marvel has not revealed any official plans about introducing mutants, it's heavily speculated that we'll have them hinted at in the upcoming show WandaVision.
In my article suggesting the different ways on how mutants can be introduced, I thought the best solution was to make use of Scarlet Witch and her reality-bending powers—kind of a reverse House of M situation.
We don't know what's in store for the future of the mutants in the MCU, but hopefully, WandaVision gives us a clue when it comes to Disney+ before the end of the year.
