Olympic swimming champion Michael Phelps will compete for the 20th gold medal of his career Tuesday night in Rio.
The American will square off against South Africa’s Chad Le Clos, a longtime rival, in the men’s 200-meter butterfly.
Phelps, a five-time Olympian, was caught on camera Monday giving his opponent an intense glare.
Folks on Twitter, using the hashtag #PhelpsFace, have likened the swimmer to an axe murderer and Anakin Skywalker when he transformed into Darth Vader.
