He didn't know what the true Talon was like at first; when he found out that Talon's goal was quite different from his own, which was to make the world a better place, he deserted Talon.
Fresh off the Paris map debut, the good folks at Blizzard have now unveiled the new Overwatch hero Baptiste. Cuerva explains in that recovered log that even though Baptiste is a medic, he has a very accurate shot, so it sounds like his in-game kit might have an offensive ability or two in addition to abilities meant to keep his team alive. He's a healer with a serious damage capability.
Regenerative Burst: Baptiste activates an intense regenerative burst that heals himself and nearby allies over time. Allies inside the barrier will become immune to death - their health will not fall under 20% of their full health until the generator is either destroyed or its duration ends. Baptiste moves around the battlefield with Exo Boots, jumping over obstacles and clearing distances that would stop other heroes. His alternate fire lobs grenades that heal allies near the point of impact. The newest Overwatch hero is called Jean-Baptiste Augustin and he is a medic armed with some seriously powerful abilities.
Amplification Matrix (ultimate ability): Baptiste creates a matrix that doubles the damage and healing effects of friendly projectiles that pass through it.
Baptiste is now available on the PTR on PC, which means he should be playable for all Overwatch gamers shortly.
