Video: Heroes of the Storm wouldn't be a true Blizzard arena brawler without someone representing Overwatch. And finally, after all the characters added from Diablo or WoW, the first Overwatch hero is ready to make her debut. Tracer looks like an assassin type hero here with a quite powerful basic ability: she can move while attacking. That's a first in Heroes of the Storm, so it could make Tracer a powerful and popular character.
She's originally a hero who can manipulate time, and looking at her other skills, that won't be much different here either. There's a blinking ability with 3 charges and a cooldown, a melee attack and a skill that "rewinds" the player to the position they were in three seconds ago.
