Rensa (IdesOfMarch)

Name: Rensa
Age: around 500 human years
Species: Demon Oni
[i]Appearance: around 11-12 feet tall 400-450 lbs red-skinned demon in his large form. He has red and black tints in his eyes but the shape of the pupils is unknown. His white hair runs down to his neck but looks to have been repeatedly cut by a not very steady hand. His teeth were razor sharp but somehow still pearly white. Upon his head rested two horns around one to to feet in length. He wears a baggy set of pants and a half toga to cover one of his shoulders. A belt with steel bulbs is around his waist to keep this outfit together. His smaller form is more human looking though he wore the same clothes. A black skin tone with only two medium horns poking from his head. His weapons consist of a blood infused kanabo, two nandochis, and two katanas for when his arms split into 4.
Abilities: Supernatural Condition, Contaminant immunity, Disease immunity, shape-shifting (only to shrink to a smaller form or to his regular one with either 2 or 4 arms) Supernatural Combat, Supernatural Durability, Supernatural Endurance, Supernatural senses, Elemental resistance (fire and magma), Fear Inducement, Matter ingestion, Infinite Digestive System (needs blood), Natural weaponry (Claw retraction, Horn Protrusion, Powerful Bite), Powerhouse Physiology, Regenerative healing factor (level dependent on how much blood he uses), and fire and magma kenosis though he needs ample amounts of blood to do various things due to this power.
Weaknesses:  he has no free will and is weakened by harsh cold or holy water. Or if he is using fire or magma kenosis he is extremely vulnerable to regular water. He is quite slow at first while his blood abilities are not in use and he lets his anger drive him. Even if that means he hurts himself or others. As long as he gets the job done. Whilst in battle if he gets hit with too many blows and can't get the blood to regenerate his third eye will open which is his most vulnerable point. If that spot gets damaged it'll most likely be fatal.  
Personality: practically unknown. Other than in combat, Rensa is very unreliable. He has not been able to think for himself.
History:  He was only created for battle. After this battle, he's been chained to do whatever for Destiny after she bested him and his old ruler in battle. Since the fight, he's only gotten stronger. Mastering each ability of his. Rensa goes around fighting or doing whatever for his ruler no matter the task. Though if he were to be bested, maybe, just maybe, he could be set free.
