I've had these ideas for a little while now, so I am deciding to share them. I tried to be as simple as I could, and try to be creative with these ideas. I was kinda lazy with writing it so bear with me here.
Prehensile Tail: With this the user can use their tail as like an extra limb. They can pick stuff up with it, hold objects, use it in combat as like a fist, balance themselves on it, and hang from it like a possum. The user cannot make it grow.
Fabric Accessory Weapons: With this, if the user is wearing a scarf, ribbon, bandanna, or any accessory made out of fabric, the accessory becomes part of their body, meaning they cannot take it off. The user can use the accessory as a weapon with the accessory's threads, pick up stuff with it, and about almost everything as the Prehensile Tail idea above.
Head Reattachment: The user can live without their head. They can also easily take it off and reattach it with no problem, and maybe even use it as a weapon if they're skilled enough.
Welp. That's all that I have so far. Sorry that it's lazily written, I'm tired. uvu
