Even though I like some of your ideas, it doesn't fit the character I have in mind. Kick Shot is more of a (attack) speed/agility type kind of guy. He's the kind of guy who runs around you before suddenly jumping into your face with a gun boot.

You know what, I could keep trying to convince you guys what I'm talking about, or I could show you guys my inspiration.

Also, rewatching this got me an idea: 
Bonus damage based on the enemy's max HP. I call it: The bigger they are, the more that they bleed.
