Demaro

A character from Tails Gets Trolled.

World of Purest Hatred
Most of Demaro's past is unknown, appearing at a satanic ritual where a few fellows arrived by accident. After drinking Satan's blood, only a few survive, granting him neutral powers. Demaro was one of the two people there to get something more than just neutral powers, Demaro gaining a Third Eye. Demaro is able to keep his powers by constantly being angry, unlike most other neutrals who as their name implies must remain emotionless to escape internal conflict, he escapes the conflict with having his heart filled with nothing but evil. From there, he and his younger brother, Garry, joined the Trolls. However, Demaro and Garry can no longer stand each other's presence, and Demaro leaves, after unleashing his anger by using his wires to pierce Garry's left part of his face permanently crippling it. Many time later, they meet again when Demaro comes looking for Coyote, his rival who keeps besting him somehow. So they fight until Garry reveals his hidden power of Earthmancy, and using his robotic nanomachines clone to bring Demaro to near death. After crushing his arm into a pulp, Garry uses his final trick of Magma-bending to turn into an impenetrable burning armor, and prepares to finally execute his brother. However, before he can do so, Demaro prayer to sata activates his Third Eye that sends Garry to another dimension, where his soul gets eaten by some sort of satanic beast, which grows stronger.

After this, Demaro gets into a fight with Coyote, where Demaro uses multiple powers in an attempt to defeat Coyote, but they all fail one by one to Coyote's smugness. Utterly hopeless again, his eye turns him into DEMARO BLANCO, who manages to CUT COYOTE'S NECK (which would have mattered if he couldn't use his wire hax to close it). After a while of mocking him, Demaro returns to normal once again losing memory of anything his third eye did. However, before Coyote can end him, his Third Eye activates again, and summons Coyote into the hell demotion with the satanic demon. Coyote manages to control Demaro's satanic demon, somehow.
