* History is incomplete.

Charles Wheatlesby, also known as "Cachinga", is an assistant to Dr. Rick Spartan on his adventures.

Physical Appearance

Charles is a tall Caucasian man with a lean physique, a small bulbous nose, and short, dark brown hair. He is often shown wearing olive-colored clothing, a white undershirt, a purple tie, and knee-high black boots.


During most of his first appearance, Charles remained silent for his native persona Cachinga, and was shown to be weary of Rick's treatment. This was further amplified when it was shown he was perfectly literate with an English accent.

He is also vegan and has a preference for gluten-free food.

Skills and abilities

He is quite skilled in tossing a spear.


Early life

He is an Oxford graduate.

Scooby-Doo! Mystery Incorporated

Season one

Spartan gave him the nickname, "Cachinga", because it would sound better when he told the stories of his adventures, to have a native guide instead of "a dude with a spear." Charles seemed annoyed about this, so he was a possible suspect to be the Headless Horror. (Attack of the Headless Horror)

Season two

Charles remained with Spartan even after his separation with Marion Spartan. The two returned to Crystal Cove to help the Mystery Incorporated gang capture and unmask the Gluten Demon. For most of the mystery, he was paired off with Daphne and Velma. He was glad to see Spartan in high spirits when Marion agreed to a reconciliation, and the two departed from town afterward.
