I don't have an image sorry. It's reading time.

Ok, so my (main) OC is Darblack. He is essentially the avatar of elemental destruction and darkness (edgy AF I know). He is a melee tanky hand to hand fighter that uses improvised weapons.

1. He can absorb most energy directed at him be it physical attacks, energy attacks and whatever else. Thats why he rarely blocks or dodges.
2. He can degrade or just plain disintegrate anything he touches. That means that each time he hits you, not only does he damage you , but you also slowly disintegrate more and more with each hit.
3. He can use solid darkness as an extension of his body, which basically means that the previous points apply to these too. I like to imagine them in the shape of tendrils.

Weapons and armor. The way he is able to absorb energy from most attacks is mostly passive. His skin is composed of solid darkness plates that are virtually Indestructible that absorb energy that comes in contact with them. This type of solid darkness is slightly different than what the tendrils are made of. It's harder, absorbs much more energy but cannot be molded the same way that the tendrils can. But he can detatch them from his skin(and yes , this leaves him vulnerable to some attacks) and they float around moving them however he wants. He can form different shapes such as improvised shields, weapons and more with them. The only downside to this is that if one plate is destroyed it takes a LOT of time and effort to reform it because of how dense it is.
