User blog:Lover of the Muse/Toxic Chainsaw

Dokutan Koboyashi (小林毒湛) also known as the villain Toxic Chainsaw, was the father of Yuki, a Tartarus escapee and the main antagonist of the Chainsaw Revenge Arc.

Appearance
Toxic Chainsaw is a tall man with sickly green skin and a muscular physique. He has wild dark green hair and yellow eyes.

Abilities
Enhanced strength: Dokutan possesses an immense amount of raw physical strength that comes from years of intense training. His physical strength is comparable to that of Endeavour.

High Durability and Pain Tolerance: Dokutan is able to withstand a lot of punishment before his body is visibly damaged and even after his body is damaged he doesn't let the pain stop him.

Quirk
Toxic Chainsaw( 毒々チェーンソー Dokudoku Chēnsō) : his quirk makes him poisonous to the touch and allows him to transform his hands into chainsaws that secrete poison. When the blades are running they constantly fling droplets of poison, and if he keeps the blades running long enough the engines will start to emit toxic fumes.

Dokutan can dial up or down his toxicity but he can never fully turn it off. Besides himself, the only known individuals immune to his poison are his mother (from whom he inherited the poison aspect of his quirk), his wife (who developed an immunity by repeated exposure to minute doses) and his son (who inherited his immunity).

Personality
Dokutan is a vindictive and ruthless man, since the Tartarus jailbreak he was driven by  desire to avenge his defeat by All Might which led to his imprisonment. The first thing Dokutan did after escaping prison however was to reunite with his wife and son. He recruits his son to help him take revenge on Toshinori Yagi.

His son Yuki Koboyashi
Yuki Koboyashi (小林雪) also known as the villain Frosty Chainsaw, is the son of Toxic Chainsaw, and the secondary antagonist of the Chainsaw Revenge Arc.

Quirk
Frosty Chainsaw(霜 チェーンソー Shimo  Chēnsō ) his quirk makes him cold to the touch and allows him to transform his hands into chainsaws that secrete a liquid similar to liquid nitrogen, and when the blades are spinning they fling drops of this liquid. He can increase or decrease the intensity of his cold but he can never fully turn it off. Beside himself the only person fully immune to his cold is his mother (from whom he inherited that part of his ability).
