Prince Charnock is a character that appears in the Adventures of Sonic the Hedgehog television series. He is an alien and the prince of the planet Rhombus.
Prince Charnock is a green lizard-like alien with a squid-like head. As attire, he wears a small white hard hat with a small golden crown on top, a short-sleeved beige jacket, baggy white pants and black boots.
When Charnock was heading to Rhombus in his spaceship with Splorg after being on a vacation to be crowned king of the planet in just two hours, or his two-year old baby brother would become king and destroy Mobius out of youthful ignorance, their ship was caught in Robotnik's new Electro-Suction Plate. The two of them crash-landed on Mobius, leaving their ship shattered to pieces, and they were caught by Scratch and Grounder. However, Sonic the Hedgehog and Tails rescued them and helped them locate the missing pieces of their ship. However, after Sonic found most, the ship's two most important pieces were missing - the cockpit's pressurizing canopy and the naviagational nose-cone.
The four headed off to find them, quickly finding the cockpit canopy. Charnock was fascinated by the planet's nature but was nearly eaten by a snake, stepped into a river and fell down a cliff. During a landslide, the heroes and the robots accidentally mix up the ship's nose-cone for Grounder's nose. Sonic defeated Scratch and Grounder, but soon discovered Robotnik had Charnock, Tails and Splorg prisoner. Sonic gave himself up to save his friends and Mobius, and the aliens got their nose-cone back. Not feeling right about leaving Sonic, Charnock had one last trick up his sleeve, photographing Robotnik's Egg-O-Matic, but "accidentally" knocked over a giant rock that crushed Robotnik. The four raced back to the spaceship and Charnock and Splorg headed off to the coronation, though not before Charnock revealed to Sonic and Tails of how old his baby brother really was and why he would destroy the planet.
Prince Charnock seems to be somewhat of an idiot. He is a bit scatterbrained, overly optimistic and always eager to see new sights, becoming oblivious to the dangers his actions end up invoking. However, he has a good sense of right and wrong, and believes that to be a good king he must not prioritizes his own goals over others' well-being. He also has an upper-class English accent.
