A Koopa in Remnant

Notice

There was one more thing that I forgot to mention. Bowser's weapons and gear.

Striker Shell- This shell was used in Mario Super Strikers. It can tank a punch that could potentially destroy a rock in his five times harder than steel. Not even a punch from Yang using her Semblance could put a dent in it. Instead, it would probably break her wrist. However, if Hazel Reiner were to punch it, it would leave a dent and an aching hand.

Striker Claws- These claws were crafted for Mario Super Strikers. They are incredibly sharp, and can extend like grappling hooks to hook onto cliffs ledges or opponents. They can use Dust to change the elemental advantage the claws can give. However they have a tendency to get tangled, which is their only weakness so far.

Trap Bludgeoner- Bowser's bat used in Mario Super Sluggers. The difference between this and his bat is that it's more durable and can transform into an elephant gun that can shoot small Bullet Bills. The spike can also extend to about 4 1/2ft, like the spike traps in the Mario games.

Clown Car- His clown car is like all the other models in the game series. It can go underwater, fly in the air, shoot cannon balls, drop bombs, etc. A new feature added is it's ability to use Dust bullets as ammo.

Now for his Semblance and Abilities:

Bowser's body can transform into a different form to help adapt through certain situations like environments and combat. The many different forms are as follows:

Giant Bowser- His mass, size, and strength increase drastically. He can reach 300 ft tall which is useful for fighting bigger enemies. (This is not part of his Semblance. It's more or less a failsafe if he is in critical danger.)

Metal Bowser- Increases defense and density to maximum, however it makes him much slower. He can't breathe fire but he can use electrokinesis. (It is cannon. Bowser
can actually use electricity as seen in Mario Galaxy)

Copy Bowser- Can make fake identical copies of himself, however they're not as strong as the original.

Fire Bowser- Increases fire attacks to maximum and makes him immune to other fire attacks. However, he's more susceptible to water.

Aqua Bowser- His least favorite form. He can breathe underwater and takes less damage from ice. However he is more susceptible to lightning.

Molten Bowser- He gains molten armor on his body. He's more susceptible to Ice attacks, but his physical attacks increase drastically.

Dry Bowser- basically Sans Undertale except he won't die in one hit and it doesn't tire out easily.

Finally Giga Bowser- His most powerful form. All of his powers are maxed. His defense and stamina rival Hazel Reinhert's. His dark magic attacks increase as well. However, this form puts a lot of strain on him so he can't keep it for very long. The maximum time he can stay in it is about 15 minutes. Anymore and he will transform back.

If you have any suggestions for any new forms, let me know and I'll see what I can do.
