Dark Super Vanya

Upon seeing the unconscious Leo, Raph, Donnie, Mickey, and the unstable April, Sonic displayed intense rage and anger toward Shredder, Baxter Stockman, Xeler Breadwat, and Tiger Claw, concealed by their demonic, sly grins and terrifying laughter. He discovered the phenomenon of murderous pleasure from smashing and was at full strength. He could also be described as somewhat insane and uncontrollable, so much so that Karai voluntarily reassured her by hinting at his excessive aggression.

While Dark Vanya's full potential hasn't been fully explored, it has been shown that in this form, Vanya's speed and strength greatly exceed his normal strength. This move occurs at high speed, fast enough to tear through a robot, snapping vertical walls in half. He also possesses enough strength to dent metal and shatter a robot's face with a single blow.

Dark Vanya has an intermediate stage of his transformation. At first, he's not particularly different from Vanya himself, except that his eyes become more pointed and his human form is much darker. However, in his final stage, differences are noticeable: his skin tone, like his skin, becomes darker, his back quills curl upward, making him resemble Super Sonic (hence the reason he's called Dark Super Vanya), and his pupils resemble falling. Dark Vanya also emits a dark blue smoke aura. Notably, he retains his white gloves and black and red sneakers throughout all stages.
