Shadowy Figure

Shadowy Figure, simply known as Shadowy and later Shadowy Venomous, is one of the main antagonists of the 2017 TV series OK K.O.! Let's be Heroes. He is a mysterious glorb dealer and the archenemy of K.O., who is later revealed to be the turbo form of Professor Venomous. He serves as a major recurring antagonist in Season 1 and Season 2, and one of the two main antagonists of Season 3 (alongside T.KO.).

Like Venomous, he is voiced by Steven Ogg, who also portrayed Trevor Philips from Grand Theft Auto V and Simon from The Walking Dead.

Shadowy Figure appears and tells K.O. that he senses great 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 POW Card, which states that he is a Level 8 hero, convincing K.O. to follow him.
