April 22, 2026:We added information about the leaked Overwatch characters to the guide. Who are the Overwatch characters? The current Overwatch roster boasts 51 heroes, with Sierra being the latest addition to the game. New heroes are typically released every two seasons, so keep an eye on this guide to see who has been added to the game throughout 2026. As of Overwatch Season 1, every hero has received a sub-role. These sub-roles provide unique buffs to your hero, so it's important to know what each one does before heading into battle. We should point out that while you can play as all the Overwatch heroes in most game modes, not every hero is available to play in Stadium. Check out our Overwatch Stadium guide to see which characters are available in the MOBA-like game mode.
