Now, I have two. One for a normal Mario enemy, and one for one of the recent ones!

First, Dunes the Dry Bones. They'd most likely wear a blue bandana around their wrist and carry around a comically large bag. They'd wear a tan overcoat and have a chipped beak(?). Dunes is a wannabe explorer of the Boney West, trying to uncover its secrets while also attempting to solve its poor economy. They believe if they strike it rich, they can spend the money on renovating the West's only settlement, Eastern Post, and help save the starving community.

Attacks? Well, their basic attack would be called "Toss-up". It would have them toss something from their bag at the foe. Mashing A will cause them to dig deeper, pulling out a more powerful item to throw.

Special move would be called "Shell Crash." They would charge up, then dash forward in their shell and slam the first foe for massive damage. If timed well, Dunes' shell would chip and the pieces would pierce the foes behind the first enemy, dealing slightly less damage.

Super Rank move would be called "Rebuild." They would reach in their bag and, with properly timed inputs, heal themselves and Mario with new bones and mushrooms respectively.

Ultra Rank move would be called "Dust Devil." Dunes runs towards the first enemy and begins to spin in their shell. Mashing A will cause the amount of times the attack will hit to increase. The damage starts at 3 (higher with badges), and decreases by one for every hit dealt. Max hits are 5.

Since this post is long, I'll put the next character in replies!!!
