[@HarbingerKurahi] Doc Doctor tends to just scale his characters to whatever he's fighting anyway, Gonad will probably be akin to the Hulk if you fight him with that character.

That being said, some issues with your character if you intend to fight under T1 Eden:

Black Lightning Control: User can create, shape and manipulate the darker, destructive and consuming aspects of lightning, which ignores the limitations and weaknesses of normal lightning. Black lightning not only discharges energy, i[b]t shocks and destroys everything it touches[/b], including regular and white lightning. 

If that's flavour text, it shouldn't be there, if that's an accurate description of the damage potential of said ability, it's not going to fly. You can't instantly destroy anything, that would be an absolute.

Lightning Mastery: Through a millennia of rigorous training and practice Kurahi has gained complete and total mastery over the element of lightning granting him [b]total immunity to it in all it’s forms[/b] as well as allowing him to control an and all forms of lightning, even extending so far as to be able to manipulate lightning that is conjured by others through spells or natural ability. 

Another absolute, you can't have completely immunity to an element, especially when you consider what lightning is. The kinetic impact alone bears mention, let alone the heat. 

Poison Immunity: Due to his body’s ability to generate poison Kurahi has immunity to poison unrivaled by any other living being. He is [b]immune to all forms of poison as well as most diseases[/b]. 

Having complete immunity to all poison and disease just because you make it is not a realistic ability in T1 Eden. You can have your body's natural poison act as an anti-venom/poison agent, which breaks down and destroys poison or disease, but it can't be infallible nor instantaneous, in other words, absolute, except for cases where logic takes over (for example mechanical constructs and other non-biological entities.)

Grievance: Grievance was once wielded by the horseman that went by the same name. As the weapon of a horseman it is both unbreakable and forever sharp. [b]When in play Grievance puts off an almost unbearable aura of pain and fear that can drive most weak willed beings such as humans and vampires completely insane if they come into contact with it[/b].

Passive auras that drive humans (and Vampires?) insane aren't going to fly, it's an un-interactable power, and a nasty one at that, I'm assuming you know what that means. 

Everything else should pretty much be balanced by T1 Eden rules, but those things would be issues under most tournament rules even outside of T1 Eden.
