What character would you like to see in the game that there abilities haven't been used?

Abilities like, ice-based, fire-based(Ghost Rider doesn't really count, that's hellfire), etc.

To me, personally I would like Gilpetperdon(Will never happen, if he came in, he would be stronger than Thanos canonly), we need a fast runner character badly. I can just imagine a skill set of moves:

1 Star skill: Fast Punch:

The fast runner character punches enemy, runs back offscreen, and punches on the other side, so 2 punches (Only hits one enemy).

2 Star skill: Marathon:

The fast runner character jumps back normally and runs fast forward hitting any enemy in its way one time and going offscreen, the character reappears on the same spot they pressed the skill, so it's like they ran around the world to meet at the same spot).

3 Star skill: Hit-and-Run:

The fast runner character hits the enemy, the same mechanic works like Carnage's 6* and 3rd skill, the fast character will hit the enemy 4 times if there's 1 enemy and no other enemy. If there's multiple enemies, then the character will punch the closest one, quickly run to the next closest, and so on for 4 punches.

4 Star skill: Blitz:

The fast runner character jumps back, goes into a marathon sprinting position where his/her hands are on the ground and his head looking up, he/she runs forward offscreen, you only see a blur, he/she comes from the top right corner down to the bottom left corner, comes from the right bottom corner to the top left corner, and comes from the left side to kick the enemy where he/she stops, and when the character goes into the corners, he/she technically punches them, but you'll see a blur so you can't see it. (Can hit multiple enemies, and if they're in the line of the ways he/she runs to)

Passive: Momentum Drive:

30% chance when hit, movement speed and dodge increase 20% for 7 seconds, cooldown time 9 seconds after active.

6* Star skill: Blinding Speed:

The fast runner character runs around the enemy creating a large tornado that pulls in enemies, does a lot of rapid damage, the tornado lasts for 6 seconds and after 2 seconds, you can get out of the animation and can attack then.

Leadership: Fastest Being Alive:

All Speed +30
