Two (unknown birth name) is a reccuring antagonist of the season fourth of Stranger Things. He was one of the test subjects experimented on at Hawkins National Laboratory. He is portrayed by Tristan Spohn. Two was born sometime in the 1960s with the ability of telekinesis. He would eventually be taken to Hawkins Lab under the care of Dr. Martin Brenner under the name "Two". Two was the oldest known experiment, being told that One did not exist. Throughout the late 1970s, Brenner obtained a plethora of children who also possessed telekinetic abilities, though Two proved to be the most powerful and strongest of the children, which led him to become cocky and mentally unhinged since he wanted to be Brenner's favorite.
