As Blizzard confirmed, the next Overwatch hero will be a vigilant medic called Jean-Baptiste Augustin. They also released a video that lets us see the backstory of this interesting character.
Basically, Baptiste grew up on the battlefield and now he uses his skills to make the world a better place. Not a very original backstory, but hey, it serves the purpose.
We still don't know when he might be available on the test realm, but that should hopefully be very soon. We will keep you updated, that's for sure!
Take a look at the official video to see him in action!
