Bloo

Bloo makes a lot of mistakes from time to time, but he doesn't notice it until his friends point it out to him, though he does make things right in the end, especially to his friends. Bloo sometimes tries to do the right thing but then lets his ego get in the way, but he does get back on track in the end when he realizes that he let his flaws get the better of him.

Bloo often has a tendency to accept outrageous ideas as fact to explain seemingly mundane occurrences, and bends others to his will, going so far as to make them go against their moral standards. Bloo also displays a passion for paddle ball, although he never succeeds in making the ball hit the paddle (with a few exceptions), to which he insists that all his paddles are broken. For bowling, it's the opposite, as it is shown that he's very skilled at it, although he doesn't appreciate the sport.

There are times when Bloo's cleverness is muted, however. He sometimes can be tricked by rather simple appearances. Occasionally, his thoughts tend toward the bizarre, going as far as paranoia. Lessons in the form of metaphors are lost on him. His cleverness also has limits when he is distracted. However, Bloo has only been intentionally outsmarted a few times throughout the series.

Bloo has developed a severe case of laziness when it comes to simple tasks. One example of it was during "Squeeze the Day", when he dropped a potato chip on the floor and refused to pick it up. He went all throughout the house just to find someone, even passing the chip several times, to pick it up so he didn’t have to, making him do more work trying to find someone to pick up the chip than just picking it up himself, showing his refusal to do any work.

Bloo doesn't hate rules, but he doesn't know how to obey them, when in the first episode he refused to listen to Mac not to throw a vase at Terrence's head, because in general, Bloo doesn't, but only hates the rules applied by Mr. Herriman.

He's at the core of his personality, clever and self-centered. In Season 1, Bloo was shown to have a slightly gentler personality; however, when Season 2 began, he developed a mischievous, jealous, greedy, narcissistic, and immature personality. He is also shown to be a rebel, compared to Mac, who is the smart one. Bloo is abrasive, troublemaking, immature, jealous, and manipulative, partially due to his restless energy, cleverness, and delusional narcissism. He has often demonstrated a hyper, albeit nonchalant personality and is sometimes incredibly naive and childish.

Blooregard Q. "Bloo" Kazoo is one of the two main protagonists (alongside Mac) and a young imaginary friend created by Mac in Foster's Home for Imaginary Friends. He is voiced by Keith Ferguson. Bloo is sometimes considered the series' secondary antagonist depending on Bloo's ego. He is the only character to appear on every episode of the show, including shorts.

Mac created Bloo when he was three years old, meaning that, by the start of the series, they had been creator and creation for five years. According to a trading card in the Foster's Home for Imaginary Friends Leapster game, Mac created him when he had to give away his favorite blanket.

Bloo is a blue-colored, dome-like cylindrical creature. He has round eyes, curvy arms, a little mouth, and stubby, fingerless hands. He is exactly 2 feet tall, and weighs 10 pounds when dry. When he walks, he makes squeaking sounds akin to that of a shoe.
