Species: Elemental (actually a living compilation of 'corruption' energy, but it's close enough.)
Appearance: (Bad drawing)
Weapons: Anything he can form from physical 'corruption' energy.
Basically, he makes items out of corruption, such as swords, or massive badminton rackets, basically whatever he feels like doing.
Has a thing for making corruption tentacles and stabbing enemies with them.
Powers/Abilities: Corruption is the physical formation of 'corruption' energy, an odd 'elemental' energy inaccessible to all but him, along with this, due to what he is, he has access to all corruption energy, throughout every multiverse in existence, and gains energy from any 'corruption' happening around him, or that he causes.
He has access to every ability/function his status as living 'corruption' brings.
His form is highly manipulatable due to being composed of physical energy.
While he usually shows up in a humanoid form, he can easily convert it into any other formation, logical or not, in instants
can shift form by making holes in himself to avoid weapons if he notices them.
If his form is split by damage, even a small amount, he can quickly form it into another Corruption.
He can also do such at will, and each Corruption has their own level of sentience.
He can and will use physical 'corruption' tentacles to latch onto others and use the, like a marionette, forcing them to either attack themselves or comrades.
Can fire physical balls of 'corruption', send out a physical shockwave of it, make temporary (I.e. exists so long as he 'concentrates' on it) objects/buildings/etc, etc, etc
He also has devastatingly high mental strength, and possession abilities which he calls 'corrupting others', but he can only access such if another attempts to use some form of telepathy or similar mental based attack/ability that would affect him enough to allow such a connection.
While corrupting doesn't change the person affected, it allows Corruption permanent access to their mind, and the ability partially affect thoughts and emotions (mainly through projecting whispers into their mind), communicate with them, or try to take control of them.
Weaknesses: Prideful, irritable, certain kinds of music (just pisses him off), boredom (i.e., gets too bored he'll probably just leave...
Or kill people and then leave.), if you can think up/make a deal that he'd agree to he will follow it to the letter (kind of, all you have to worry about is any loopholes he can find), Order (and yes, that is capitalized for a reason, a reason which basically makes this useless in truth)
He also usually fights in a very unskilled, if very, very destructive manner.
Basically just charges in and starts wrecking everything.
Personality: Cruel, sadistic, 'playful', honourable only in the terms of following deals (this has no meaning on any loopholes he finds), insane.
