Chameleon Jr. is a minor/background character in OK K.O.! Let's Be Heroes. He made his debut in "My Dad Can Beat Up Your Dad", despite being a hero, he is more of a villain or anti-hero.
He is voiced by Tony Revolori
Chameleon Jr. is short with scaly green skin. He has large yellow eyes, a pointed nose, and a mouth full of sharp teeth. He has tattoos on both of his shoulders to compensate for his small size. His outfit consists of a pale blue sleeveless top with purple stripes, and blue jeans with no footwear.
On one hand. Chameleon Jr. is shown as a very stuck up and spoiled child, having no patience for things that don't go his way. This is due to the fact that his father gives him everything he wants.
On the other hand, he seems outgoing, hanging out with others, such as Red Action and more.
