Shadowy Figure

"Never mind that, what matters is that I see you. More importantly, I see something in you that no one else sees. The great power that courses though your veins."

- Shadowy Figure to K.O. Shadow Figure is a major antagonist in ''OK K.O.! Let's be Heroes.'' He is a mysterious, unknown person who seemingly has plans regarding Lakewood Plaza Turbo and K.O., although what they are is unknown. He serves as the Big Bad of the episode "T.K.O.".

T.K.O.
After hearing K.O.'s frustration and desire for power while he throws out the remains of a Darrell, Shadowy Figure appears and tells K.O. that he senses power flowing through him and offers to help unlock it. While initially willing to go with him, K.O. then stops, stating that he doesn't even know who he is. With that, Shadowy Figure shows him his hero card, which states that he is a Level 8 hero, convincing K.O. to follow him.

In the woods, Shadowy Figure tells K.O. that the secret to his hidden power is his anger, specifically the anger locked deep inside of him, and that he must unleash it in order to become powerful. While inside of K.O.'s mind, Shadowy Figure shows him his anger and reminds him of all the things that his friends had said to him (somewhat warping the meaning of them), causing his anger to grow, although K.O. fails to unleash it. While Shadowy Figure attempts to try another method, K.O. grows even more angry at how everything he's tried to increase his power has failed him, causing him to grow even more angry to the point where he unleashes his anger and gives Shadowy Figure what he wanted; K.O. to turn into the villainous T.K.O.. Shadowy Figure, delighted with this outcome, unleashes T.K.O. on Lakewood Plaza Turbo.

After T.K.O. is defeated and imprisoned by K.O., K.O. tells his mother Carol what happened and pulls out Shadowy Figure's hero card. As Carol is holding the card, it glitches out and reveals that Shadowy Figure's hero level is actually -8, meaning that he is a villain. As everyone is reconciling, Shadowy Figure is seen standing on the roof of the frame store, laughing to himself and saying "Soon". Brandon notices Shadowy Figure and tries to tell A Real Magic Skeleton about the man standing on their roof, but he ignores him, resulting in Brandon deciding that he likely isn't important.

Appearance
Shadowy Figure is a tall, slender man with grayish-purple skin. He wears a light black trench coat and a black hooded scarf that leaves only his mouth, nose and chin (which bears strange dots) visible. He also wears dark black gloves on his hands and dark black boots. Based on his voice, he possibly also wears a voice distorter of some sort under his coat.

Trivia

 * The visible portions of Shadowy Figure's face bear some similarities to fellow villain Professor Venomous, suggesting that there may be a connection between the two.
 * Shadowy Figure is the only villain in the series to have not been played for comic relief in someway.
