Nope. Scales.
Basically it was a character for One Piece... except her power belonged to her brother. And since their other brother had elemental dragon transformation, I gave the one brother energy beams. (Draco had was a western dragon who could shoot energy, Serpere was an eastern dragon who could control the four elements, Vypera just could control steel).
When I wanted to use Vypera in a One Piece RP, I still wanted to use the Dragon-Dragon Fruit of the West, so I gave it to her. But I never got a chance. So I figure, fuck it, she's a mutant now.
Confused? Here's the fruit description from her One Piece CS. Easily adjustable for this RP (and no. She won't actually transform. She'll only have her hybrid form. Like Leon being a walking tiger. Or Beast. Or Nightcrawler, you get it. Unless you WANT her to transform. I just figured that her full form, while fun, might not fit)
-Devil Fruit(if any): Here we go: The Dragon-Dragon Fruit (Ryu-Ryu no Mi): Power: This Mythical Zoan-Type Devil Fruit allows its user to transform into a Western-Style Dragon with focus on strength and power. It also allows her to fire energy beams. She can fire these beams in any of her three forms from either her mouth or palms. Her hybrid form mostly resembles her normal look except she’s not 6’ 8” instead of 5’ 6”. She gains one scale on each of her cheeks; her pupils’ slit, while her irises turn yellowish-green and her sclera turn black. She does gain fangs (that elongate for biting) and the rest of her teeth sharpen as well. She gains scales all down her back, running along her spine to her new tail which is about 6” thick at it’s base and about 5’ long, her forearms turn into those of a dragon, being scaly and ending in five clawed fingers. Her forelegs do the same, except she only has three front toes and one back toe. The scales on her legs continue up her outer thighs and create what can only be described as “scale panties”. She also has scales from the middle of her breast to the outside (to protect sensitive parts), which wrap around to her wings. Her wingspan measures about 7’, but she can’t fly with her wings, only glide. She stronger than normal in this form, but there are still plenty others far stronger than her. For some reason, her hair also turns red. Her full form is pretty big, about 20’ from head to tail (the tail being 6’ of that). Her tail ends in a double-ended blade. Her senses are also enhanced, particularly smell. Her fiery red hair also reduces to just a mini mane on the back of her head. There’s not much else to say about her full form. She’s a dragon, plain and simple. Now it’s time to turn our attention to the fruit’s weaknesses. Well, as a new user, Vypera has quite a few. Using her beams in her human form is dangerous to her. Her mouth beam can and will burn her badly, while her palm beams will burn her if she maintains an stream for longer than 10 seconds. The scales in her hybrid form negate this (yeah, she also has scales in her mouth… I kinda just added that part) because they are strong enough to block standard steel swords and bullets. However, it is in fact possible for a strong or skilled swordsman to knock them off, causing her pain and exposing the under-flesh. And while her scales are strong, her flesh is not. It is only as strong as a regular human. She also, as mentioned, can't fly in her hybrid form. As a new user, her chest muscles aren't strong enough to produce enough lift to get her body off the ground. Maybe one day. In her full form, she is a mindless berserker, completely unable to tell the difference between friend and foe. As a result, she has no idea to protect her underbelly, which has no scales on it and is very vulnerable. Her joints are also scale-less to allow movement. Lastly, thanks to her enhanced sense of smell, she can easily be over-powered by things like garlic. However, its highly unlikely Vy will use her full form, as she is terrified of it.
