Crow (Derogatory term)

Hypercharge recommended.
Crow is, next to Spike, the oldest legendary in the game. He's been consistently good for poke damage, burst damage on Heist safes, and just being an annoyance for anyone trying to push towards an objective.
He's not extremely tanky at base, but his Defense Booster gadget and Shield gear combo can allow him to take on brawlers he'd otherwise die to at any range.
Not as good as he used to be, he still works on a lot of maps as either a debuffer (with Extra Toxic and Slowing Toxin) or as some weird slightly tanky poke hybrid assassin (I'm going insane).
Current build has a focus on the "slightly tanky poke hybrid assassin" concept, as this build allows him to do better damage with his poison, and to brawlers under 50% HP as well while surviving.Counters:
Burst damage brawlers - Self explanatory. At base, Crow is made out of paper. Without his gadget he's not gonna survive most instances of burst damage if he can't dodge them with his high speed or super.
Hard CC - Outside of his super, crow has no escape tools. He can either tank, or slow down with his gadgets. If that doesn't work, he's cooked.
Anyone with godlike aim playing snipers - If you're fighting snipers hoping to win, you're usually going to be fine UNLESS you go up against someone who mains snipers exclusively. To those snipers, you're a 2-shot kill waiting to happen.
