Bringing back and redoing a char I used while rping on youtube

Name: oni
age: unknown. Looks about 35
looks: oni appears as a tall, decently muscular man (though this is after he had completed his training. Assuming and wears a large leather overcoat, large samurai armour (minus the helmet) and a demon mask
Powers:
superhuman abilities- due to his training, oni has immense physical strength and speed. He can also shrug off wounds that would kill a normal human.
regeneration abilities- kinda self explanatory. This ability has allowed oni to get back on his feet even when he's on the brink of death. This, along with his abnormal durability, don't make him immortal. It just means he's a lot harder to kill than most humans
sword summoning- oni's sword is the physical embodiment of his fighting spirit. As a result, he can make it appear, call it to him via telepathy, and even repair any damage done to it
magic breaker- a technique oni created as a countermeasure against magic users with immense power and to test the non-magical strength of an opponent. When used, it creates a powerful sub-limiter that temporarily nullifies almost any form of immensely strong magic his opponent uses. Weaker forms of magic such as magic capable of destroying small buildings and minor healing magic are not affected. It is only used as a last resort and if it seems like it won't kill his opponent. The effects wear off if oni stops using it.
forsaken god form- a variation of magic breaker, this grants oni enhanced speed and strength as well as immunity to magic. It is used in case the use of magic breaker results in his opponent's death.
forsaken bezerker form- thought to be magic breaker's greatest flaw. This occurs when a massive amount of unhealable damage brings oni to the brink of death. He loses control of his anti-magic abilities and enters a bezerker-like state. Greatly enhancing his strength and speed. Oni also gains an immunity to magic capable of cancelling out another being's immunity to magic. Due to the very nature of this phenomenon, oni both hates and fears this ability. Claiming that any victory he has gained in this form is his greatest defeats. As he fought while unable to control magic breaker
bio: a legendary warrior turned mercenary, oni fights every battle to the very end. Driven by his goal to surpass the gods. That, and the fact that he enjoys fighting. Mainly opponents that are stronger than him. His only fear is that he will become "a mindless beast seeking only to destroy"
