Captain Charles "Chuck" T. Baker, is the deuteragonist of the 2009 movie Planet 51. He is a human astronaut from NASA who lands on an alien planet called Planet 51.
Chuck is fun loving and a 'ladies man' which is seen when he tries to talk to the women in the tea club on planet 51. He uses his looks and charms to impress people. He might not be friendly in the beginning but he later warms up to the 'aliens' showing that he can learn to accept different people. He also has the 'right stuff'. He is willing to risk his life for others like when he rescued General Grawl and 'released' Lem from his 'mind control'.
- Chuck Baker is Dwayne Johnson's first animated role.
