I was playing this free to play game Paladins, basically free Overwatch, and started thinking about champion suggestions. Which turned into this. I think their visual design for their female champs is not varied at all, so this is my idea.

Allux is a 9 ft tall robot lady melee character. She should have a voice with a quiet power to it like The Major from Ghost in The Shell, or Morticia from The Adamms Family. Just a voice that can make anything sounds threatening, with a distortion to it that sounds like she's speaking over a speaker system.

Left Mouse click is her default left punch, which knocks enemies back if it connects so she can't just spam damage attacks.

Right Mouse click fires her right hand as a ranged rocket punch that teleports her to it after a set distance. This gives her mobility.

Third ability button; holding it down puts her into a much faster 3rd person POV run than normal, letting go makes her leap forward. Holding it down and eventually pressing left mouse button turns it into a much more powerful normal punch. Holding it down and eventually pressing right mouse button fires a more powerful rocket punch.

Fourth ability button; holding it down puts her into a crouched ready state. Pressing left mouse button makes her dash forward similar to Fernando (a champion in Paladins) with a powerful punch. Pressing right mouse button makes her do a rocket powered uppercut that launches her and any enemy it hits into the air, this doesn't cost her rocket punch so she can use it when she's in the air.

Ultimate. Her left arm surges with energy, turning into a golden glow, and her next normal punch instantly kills whoever she hits and makes them explode, damaging enemies around them.
