I had a cool idea for a hack of Megaman 6. Basically, it would be Steven Universe-themed hack, and instead of Megaman and the Power and Jet forms, you could play as the Crystal Gems, with the goal to save Steven from Peridot or Jasper.
Garnet would be the power-type one, able to break blocks and punch short-range. Pressing Foward + B in the air would make her do a charging air punch, where she rockets foward while punching. Pressing Down + B would make her slam straight into the ground, eliminating enemies within the blast range of the attack.
Amethyst would be somewhat normal, with a mid-range whip attack that can be used in 8 directions. Pressing Down + A in mid-air would make her do a Spin Attack, which makes her fall straight down while curling into a ball, and when she hits ground, she rolls off like Sonic the Hedgehog, destroying enemies.
Pearl would be the quick one, with higher jumping. Pearl would attack at slightly longer range. Pressing B while standing still would make her fire a fireball (only one can be fired at a time), and pressing B while holding a direction makes her stab in that direction using her spear.
The eight Robot Masters would be replaced with some of the other Corrupted Gems from the series, like the Mother Centipeedle and such, and the goal is to poof and bubble them, and perhaps each Gem gets a different power or ability afterwards.
When you lose a life, you get poofed and your character's gem falls to the ground. Respawning after getting poofed shows the regenerating.
It would be cool if outside of the main gameplay, pressing select on the level select screen makes the Crystal Gems return to the temple/house, where you can go out on the beach or go into the rooms. entering the temple door as Garnet lets you enter the Burning Room, where you can see the gems you bubbled as a small detail, Amethyst's Room would have a bunch of junk as well as show any special items you may have gained, and Pearl's room would be for keeping track of your stats throughout the game (Time, enemies defeated, how many times you were poofed, etc).
If anyone made something like this, I would give them a cookie.
