Almost two years, but since it's sticky there should be no problem in necrobumping this.
I have some ideas. All of them are for specials.
Heatman
1- He takes a fire on the cap thing on his head (you know those lines) and collides with an enemy's head, setting them on fire which does damage for some time.
2- He turns into a box and starts rolling in a square-shaped path until he reaches a point at the roof, then jumps off. Don't think of it as Armored Armadillo's style.
3- Should require a bit of charging, but obviously faster than the normal megaman games or Fox McCloud's character. He should lit up the hole on the bottom of his foot (I'm not sure if he has one though, I just imagined it for some reason, and it kind of resembles the one on ovens so I thought it would be cool) and then just kick it, pushing the enemy far, maybe a good move to end combos.
4- A shoryuken move except with fire instead of force. I don't know, I just like Shoryukens, and I never played any SF game (even though I maybe will buy SF5)
5- A flame fist. Even though it kind of is out of character, fire and energy are kind of related, and I thought it would be if he could have another good combo-finisher special and just instead of his leg, use his fists. It would require charging as well.
Jewelman
1- A move where he incinerates his enemy into a jewel. This would be an excellent move considering that Jewelman only has one attack in MM9 and it's not that cool.
2- The ability to throw jewels at the enemy which whacks them and gives a good period of dizziness to the opponent.
3- Last but not least, I was thinking he could use his knee to attack and also make another long-dizzy move.
