Blooregard "Bloo" Q. Kazoo also known as Bloo for short, is the main protagonist/antagonist in Foster's Home for Imaginary Friends, voiced by Keith Ferguson. 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.


Bloo is a bluish violet dome cylinder that is two feet tall, and weighs ten pounds. His at the core of his personality, a clever, selfish, narcissistic maniac. Series creator Craig McCracken has said in an interview that the character was based on his childhood prior to the death of his father at the age of seven. Blooregard is abrasive, trouble-making, immature, jealous, and manipulative, partially due to his restless energy, cleverness, and delusional narcissism. When first introduced, Bloo was shown to have a slightly more gentle personality, kind to everyone and willing to protect his creator and best friend Mac.[1] However, somewhat quickly, his personality shifted considerably. Bloo developed a rather quirky personality and has often proclaimed himself to be "the best imaginary friend ever." This was in jeopardy when Uncle Pockets visited. He has often demonstrated a hyper, albeit nonchalant personality and is sometimes incredibly naïve and childish. But in Camp Keep A Good Mac Down, he seemingly caused the destruction of Wilt, Madame Foster, Eduardo, Mr. Herriman, and Coco byselfishly eating all their food and drinking all there water. Still, as demonstrated in the episode "Read 'em and Weep," he cares very deeply for his friends. When Eduardo is thought to have been "shot" by hunters, Bloo bursts into tears and confesses how much Eduardo meant to him as a friend. However, when Eduardo is later found to be alive and well, Bloo tries to cover for his previous outburst by acting flippant about the whole thing. Also on The Sweet Stench of Success Bloo shows to care greatly for Mac, and his friends as he continuously tells the Hollywood producter he wants to go home, or at least call Mac as he misses him. Also near the end when he was singing he exclaimed his friends offer more like love, and affection. Though on most episodes he'll try to cover up for his caring side. Bloo likes everyone but he likes Mac the best. If Mac were not allowed to come back and visit him, Bloo would burst into tears and would probably find a way to make him come back.

Bloo often has a tendency to accept outrageous ideas as fact to explain seemingly mundane occurrences.,[2] and bends others to his will, going so far as to make them go against their moral standards. Bloo also displays a passion for paddleball, although he never succeeds in making the ball hitting the paddle, to which he insists that all his paddles are broken. (the only time he ever was able to do it right was in "Let Your Hare Down")

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 once in his existence, by an imaginary friend named Bendy.[3]

Criminal Personality

Bloo often disregards the rules or finds loopholes in them easily, and sees rules as only obstacles preventing him from having fun. Bloo and Mac are usually the ones at the receiving end of the episode's morality tale (Mostly Bloo), usually because Bloo's antics got them there in the first place. Bloo is always making mischief in the house. He has broken eggs, stolen items, gone onto federal property, broken windows, and encouraged Mac to do the same.[4] Sometimes, however, Bloo's antics go unpunished (or at least unpunished as a direct result of his crimes) in various episodes.[5] Even when the moral lesson is obvious Bloo rarely learns it, and from episode to episode shows no growth of moral character, usually committing worse crimes as the series goes on. In Cheese a Go-Go he got arrested because he illegally used an intercom at the Space Observatory to call out for aliens to take back Cheese from Earth.

In the course of the show, he has committed a number of crimes and indiscretions such as cheating, stealing, vandalism, destruction of property, evading arrest, and even causing an imaginary friend at Foster's to be deported by framing him for one of his pranks. Bloo has apparently been actually arrested at one point or another; he knows the security guard by his first name and that he has children.[6]

At one time, Bloo actually became a mask-wearing supervillain out of jealousy after getting hair gel all over his face.[7] Usually Bloo commits crimes with a goal in mind at the end, even if that goal is to have fun, but here his crimes were fueled simply by anger made from Mac. By contrast, Mac has been a mask-wearing hero twice in the series.[7][8] Bloo has even been depicted as the "villain" of episodes, or at least the antagonist.[9]


Bloo has many people who he interacts with on a daily basis. It's difficult to say whether these persons actually like his company or personality. However it is true that the people in the house "put up" with him and accept his antics.

Despite his hijinks and self-centered behavior, Bloo has managed to forge several close friendships with the other imaginary friends in the house.


Main article: Mac

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.[10] However, Bloo and Mac are more than just creator and creation. They share their adventures and Mac visits Foster's everyday to make sure Bloo isn't adopted. They are best friends even though Bloo believes himself to be "way cooler" than Mac. Although it's not touched upon, it can be said that Bloo is the Id to Mac's Ego, seeing as how he created him from his own imagination. Mac is a level headed and moral person, and it may be through Bloo that he does and says all the things he wants but can't. Thus Bloo exist as a challenge to Mac's morality. Bloo is usually flippant in regards to his friendship with Mac, but when someone or something gets in the way of their time together or he feels is trying to take Mac from him Bloo will do anything to "win" Mac back as shown in multiple episodes.

Mr. Herriman

Bloo gets in trouble with Mr. Herriman a lot (almost every episode). The reasoning behind this is that Mr. Herriman is not a man (or bunny) of change; he takes his job very seriously and will not stand for disorderly conduct.

Francis "Frankie" Foster

Main article: Frankie Foster

Bloo's relationship with Frankie is, likewise with Mac, double-edged. Sharing much of Bloo's adolescence and ambition, Frankie is also sometimes tempted to support some of his "get rich quick" schemes to make a quick profit, and has even encouraged him to begin the scheme herself. Frankie's duties as a caretaker of the house and her mature sense of responsibility however often prevent her from completely indulging, and even tolerating at times, Bloo's rebellious activities, which puts her at odds with him on several occasions. She has also become greatly infuriated with Bloo, particularly when Mr. Herriman makes her clean up his messes. Bloo seems to constantly find a way around her rules (and Mr. Herriman's) and feels that Frankie only wants him to be happy as shown in Fool's And Regulations.

It is implied sometimes that Frankie does like Bloo, as displayed when she stood up for him in the pilot movie, listing his character strengths, though Bloo has ultimately only demonstrated these sparingly over the series and is more used to instigating havoc.

Character design

Bloo was the first character created by McCracken. Bloo is a blue thing (as he has been called) that is hard to describe, although he was first drawn as a ghost that walked and talked like a person on the original Web site. Seemingly without legs, he moves by either gliding or bouncing. One of the old character profiles on Cartoon Network's website revealed that Bloo was supposed to be a talking blanket, and some Cartoon Network promos suggested that Bloo was a living blanket of sorts, and in an issue of The Providence Journal, it's said that he is a blue jelly bean, but this was never brought up in the show. Usually, he appears armless, but he can produce arms at will. His voice has changed from a deep voice in the first episode to a lighter voice as the series progressed. On a character drawing, McCracken called Bloo, "A thumb with eyes." But most he is just called a blue blob as in the monster


  • Bloo is the only character to appear in every episode and short of Foster's Home for Imaginary Friends.
  • In the PowerPuff Girls Doujinshi web comic series, Bloo only makes an appearance in character art alongside Mac, Wilt, and Frankie; though it is possible that he will make an appearance in the future, since there is a "New Hero Pick" symbol underneath him and Mac.
  • It is odd how in Nightmare On Wilson Way, Mac explains how Bloo pulls the same prank year after year, and then how Mac has celebrated his birthday twice throughout the series, and is still the same age along with Mac.
  • Bloo is apparently allergic to flowers as seen in "Challenge of the Superfriends."
