So, if you have not seen [The Avengers: Age Of Ultron](tag:293035), this may come as a sort of spoiler. YOU HAVE BEEN WARNED!
In Thor: The Dark World, Jane Foster stumbles upon the Aether, one of the Infinity Stones - just in a non-solid form.
The Aether has the power to cause a concussive force, change matter as seen fit, and alter the entire universe. Much like, yes - you guessed it - Scarlet Witch, who has been known to completely alter universes, create a concussive blast, and even create children for her and The Vision.
Wanda gained her powers from Loki’s scepter after it was left on Earth to be used by the mad scientist, Baron Wolfgang von Strucker.
Strucker used the scepter to experiment and give powers to the Maximoff twins (since Wanda is the main focus, we will skip over Pietro).
Wanda is seen in the post-credit scenes of Captain America: Winter Soldier in a cell-like room displaying her powers (she has blocks floating and destroys them by using telekinesis to shred them).
Check out the post-credit scene from Captain America: The Winter Soldier again:
In [The Avengers: Age Of Ultron](tag:293035), we finally see Scarlet Witch using her powers to full effect. In the middle of the movie I noticed that Wanda’s powers were very similar to that of the Aether Stone itself.
They looked the same and had very parallel capabilities. In Age of Ultron, Wanda is seen lifting objects, mind-altering, and even disassembling Ultron’s robotic goons.
If you read the comics or have gotten into a minor discussion about the Wanda from the comics, you know that she has the power to completely shift the Marvel universe for reasons that I have no time to explain.
Her powers are not as complex or as strong as the Aether, but are very similar.
Just like in Captain America: The First Avenger when Red Skull used the Teseract to power his weaponry, Wanda gained her powers from Loki’s scepter...
...which held the Soul Stone (one of the Infinity Stones) that Ultron discovers and uses to give life to The Vision - which was supposed to have been his own new form.
So, it is very possible that the Stones can give people other powers outside of the known capabilities of the Stone. This could all be a coincidence, but to me - as a semi-new Marvel nerd - I think it all seems done on purpose.
