So I was thinking about a cold wind brawler, which I don't think we have. I was I thinking, I thought of a brawler named Bree. Now you'll see what she can do if you keep reading ;).
Bree: So Bree carries a freeze gun that deals 950 damage at level 1. She has 3290 HP and has the same speed as Colt.
Super: Freeze Cannon: So this one is simple. Bree spawns a Cannon that deals 475 DPS. It has 2k health. What makes Bree unique is if she hits her target three times, it'll actually make the Freeze Cannon FREEZE the enemy after every 3rd shot. This is not a Star Power.
Star Power
Speed, Not Freeze: After her third attack hits her target, she'll gain a 15% Speed Boost for 7 seconds
Ice Cap: This Star Power gives Bree and any team mate a shield if they're below 40% health. The shield will multiply for Throwers, since they're weaker.
Gadget: Hide and Freeze: The Cannon will be hidden from enemies--once they're found, the Cannon will explode in front of the enemies and freeze them for 2.5 seconds.
