Fighting Game concept: The Powerhouse (sketch)

Premise: I've started developing my personal Fighting Game Original Characters (that was soon changed in an "All female" Fighting Game after some suggestions) based on the following archetypes bluerelativity.deviantart.com/… enhanced with some pretty costructive discussions that were born when I posted the same topic on FIGHTING-GAME-FANS

While I liked the idea to have an unconventionally small and tiny Power Character, I felt like having only one "big" character was not enough, in a cast where the rest of the chars share more or less the same size. Plus I felt like my group was missing a good old BIG BAD character (since my grappler is supposed to be somewhat aligned to the "good side", if there's one).
So here's my Powerhouse (once again, no name yet )... a strange mixture between a female version of Ralf Jones and a super hero. Being the tenth character, she completes the cast and puts me finally in condition to make some proper character sheets and leave the sketches apart to go deeper with details.

Background
She lived almost her entire life in the Citadel. Since she was a little girl she heard around about the "power gauntlets", deadly weapons used by gladiators fighting in a sealed prison's arena. As she was growing up, she became the leader of a gang (later working for the Queen), and she made her technicians build a replica of those gloves. Since they had never seen such things in their life, the gloves they built were no way close to the actual ones. They didn't manage to shoot fire, but they produced little explosions with the impact instead.
While sad at first, she soon discovered that these gauntlets, while totally different from the ones she had always dreamed, were actually lethal weapons of destruction, even deadlier in her hands, since they were enhancing her already devastating punches.

(With her, we can now count FIVE people owning a pair of gauntlets, even if different the one from another:
1) The Heroine: owns a pair of Fire Gauntlets, making her able to shoot long ranged fireballs
2) The Nemesis: owns a pair of Fire Gauntlets, making her able to shoot long ranged fireballs (identical to the Heroine's ones)
3) The Palette Swap: owns a pair of damaged Fire Gauntlets, ruined during the escape (more powerful fireballs at the cost of lesser range)
4) The Old Woman: owns a pair of Chain Gauntlets, ancestors of the Fire Gauntlets. Not able to shoot fireballs, but she can unleash fast and deadly chains to hit enemies at distance
5) The Powerhouse: owns a bad copy of the Fire Gauntlets, unable to shoot but able to produce explosions at melee range)
