As if Avengers: Age of Ultron wasn't bad enough with the robot taking over everything we know have none other than Baron Von Strucker to worry about.
Wolfgang Von Strucker:
Leader of HYDRA
Satan Claw grants him super strength and electrical blast
What about our newly confirmed Avengers Quicksilver and Scarlet Witch? Not to worry although we can't label them as mutants or children of Magneto, instead they will be soldiers for HYDRA and work closely with Baron.
Not only is this a perfect way to introduce more HYDRA for use in both future Marvel: Agents of S.H.I.E.L.D. and even Captain America this gives us more to hopefully cameo into because of the hit TV Show.
