Age: Unknown
Power: Khaine turns into a large zweihandler (greatsword) which may not seem impressive but his power is dependent on who is using him. He is a tool who responds to the heart of his master or mistress. In blade form he can still talk, and even better his user does not need any training when it comes to wielding him as when their hand touches them they become masters of Zweihandler sword style.
He has had a few masters and mistress over the centuries and his power is always different. For one master whenever he was used he burst into flames and unleashed infernos on demons with every swing, for another mistress he was as light as a feather and sharper than diamonds. It all depends on his partner.
One quirk he has is that if the will of his partner is not strong enough he will swing himself (blocking, attacking, and using powers) almost like an override switch.

When his partner Activates him:
personality: He is the sword of heroes, so he has a rather large ego. He is very close to his partner due to being able to see their hearts when drawn which is why he is somewhat distant to them as he doesn't want to get attached. The lives of mortals are short lived compared to a Tizen who lives until slain. He has no romantic experience whatsoever, but it doesnt stop him from making sexual comments or believing himself to be the sexiest blade to ever exist.
History: Will reveal as the story goes on.
