Overwatch's next hero is here and he's an astrophysicist named Sigma. The character was revealed via an animated short origin story similar to ones we've seen for previous heroes

Sigma is "an eccentric astrophysicist who hopes to unlock the secrets of the universe, unaware that he is being used as a living weapon," according to the official Overwatch Twitter account In his origin story, he rambles about gravity and the possibility of harnessing the power of a black hole. We see him imprisoned and tortured by flashbacks and a somber piano melody (Gnossienne No.1). He describes both "freedom and imprisonment" as an illusion but it's unclear how these internal conflicts will translate into gameplay.This reveal has been building up since this weekend when a cryptic developer update was interrupted by a black hole and the same piano melody from today's video. This was followed by another video showing a close-up of a jumpsuit with the sigma sign as that same piano song played in the background before alarms started blaring.Sigma's role hasn't been announced yet but fans are speculating that he'll be a tank. We'll be sure to keep you posted as Blizzard reveals more details about Sigma.
