List of Foster's Home for Imaginary Friends characters
This is a list of characters from the Cartoon Network animated television series "Foster's Home for Imaginary Friends". Main characters. Bloo. Bloo (voiced by Keith Ferguson) is Mac's blue and cylinder-domed no. 71 imaginary friend and best friend who is often very immature, self-centered and egotistical as well as having a knack for getting in trouble and prone for doing kid's and children's antics. Despite all this, he still has a good heart and apologizes for his actions. Bloo loves paddle-balls even though he  cannot make the ball hit the paddle. His full name is Blooregard Q. Kazoo. He, along with Mac, made a cameo appearance in "The Powerpuff Girls" series finale, "The Powerpuff Girls Rule!". Mac. Mac (voiced by Sean Marquette) is a bright and creative eight-year-old boy and Bloo's creator who visits Foster's every day. Mac is often the voice of reason among his friends when they are making decisions. However, his extremely good nature tends to make him somewhat naive. He is very attached to Bloo and it is shown that his biggest fear is never  seeing him again, because Bloo is what keeps him happy and cheerful and vice versa. Mac becomes hyperactive to the point of a rabid mania when he eats sugar. Once in this state, he becomes impossible to control, will often become obsessed with seeking any other source of sugar. He, alongside Bloo, made a cameo appearance in "The Powerpuff Girls" series finale, "The Powerpuff Girls Rule!". Wilt. Wilt (voiced by Phil LaMarr) – The kind, red, very tall and disabled no. 1 imaginary friend with only a right arm and crooked left eye-stalk. However, in "Good Wilt Hunting", it is  discovered that he was not always this way; he was injured during a basketball game, leaving his left eye crushed and his left arm injured. Wilt exhibits consummate good sportsmanship, which he applies to every part of life he can. He is considered the nicest person at Foster's and is known for being excessively polite and apologetic, saying “I’m sorry” all the time. Wilt has a big heart, is frequently cool and collected, and, only on very rare occasions shows anger at all. His oversized basketball shoes always squeak against the floor/ground, no matter what surface he  is walking on. According to the episode "Room with a Feud", among him, Coco and Eduardo, he has been in the house for the longest time. Eduardo. Eduardo (voiced by Tom Kenny) is the big, hairy and purple Spanish-speaking no. 88 imaginary friend who resembles a mixture of a minotaur and one of the beasts from Maurice Sendak's storybook, "Where the Wild Things Are" with horns, a snout, a pointy demon-like tail and large teeth. Despite his large size, overwhelming strength, and menacing demeanor, Eduardo is usually docile, but also timid and jumpy as he lacks confidence  when he gets frightened, is very compassionate towards all kids (children, preteens, and anyone under the age of 13) and has a somewhat overly sensitive nature, crying at minor negative occurrences, and being scared of almost everything. However, he can be ferocious if angered or in the circumstance that danger befalls his friends although he does not care for others when speaking like that. Eduardo has a fondness for potatoes, dogs, and his cuddly toys. His creator, Nina Valerosa, created him to protect her in a rough neighborhood and is now a police officer. Coco. Coco (voiced by Candi Milo ) is the bird-like no. 13 imaginary friend with a palm tree for a head, a crooked red beak and an aeroplane-like body who can only say her name at various speeds and different emphases. A talent unique to her is her ability to lay colorful eggs containing a plethora of objects. Mac, Bloo, Eduardo, Frankie, Wilt, and others usually understand her when she speaks, and often translate for her. Despite her appearance and quirky behavior, she can demonstrate a perceived intelligence, principle and kindness. No one knows who her creator is as she was found on a South  Pacific island by two scientists named Adam and Douglas. Frankie Foster. Frankie Foster (voiced by Grey DeLisle) is Madame Foster's redheaded granddaughter in her 20s, addressed as "Miss Frances" by Mr. Herriman. Her parents are never seen in the series. Frankie is the caregiver at Foster's and helps keep everything in order. In spite of Mr. Herriman's fussiness and fixation with rules and cleanliness, she is usually very friendly, outgoing and laid-back. According to her driver's license in "Bus the Two of Us", she was born on July 25th, 1984. Frankie is friends with most  of the imaginary friends at Foster's (particularly Wilt, Eduardo, Coco, and Bloo) and can be described as a protective big sister to them, but sometimes gets mad at Bloo, Cheese, Madame Foster and Mr. Herriman. Mr. Herriman. Mr. Herriman (voiced by Tom Kane) is the elderly, anthropomorphic, lop-eared and rabbit-like no. 44 imaginary friend imagined by Madame Foster, who speaks with a British accent, quite similar to Bruce Wayne’s butler, Alfred Pennyworth. He wears a tailcoat, white gloves and a top hat, as well as a monocle. He is in charge of the house and is  extremely strict about the house rules, but he is also seen to put the rules before common sense, as seen in "" when he sticks to the rule written on the chained up toy box of never letting the imaginary friend who is trapped in there out despite what would happen to him if he did not. He is often found punishing Bloo for his various misdemeanors. It was revealed in "Busted" that the reason Mr. Herriman is so hard on Bloo is because he feels that, given that he is allowed to stay at Foster's even though he still  has an owner, he has already broken one of the main house rules. He is extremely fond of his creator Madame Foster, harboring great respect and loyalty to her, even at her most prominent levels of unabashed pep and energy. He has a fear of dogs (due to the fact that dogs are the natural predators of rabbits) and is easily scared out of his wits whenever he comes across one. He also has a rabbit's stereotypical obsession with carrots and will do anything to have them, as demonstrated in "Crime After Crime". Madame Foster. Madame Foster (voiced by  Candi Milo) is the founder of Foster's and grandmother of Frankie. She's an old person but has childlike boundless energy and enjoys herself to fullest. Her imaginary friend is Mr. Herriman, whom she imagined when she was a child and never gave up, and is the only one who can control him. Like Bloo, Madame Foster occasionally becomes hyperactive and mischievous. However, there are times she is shown to be the wisdom of the house.
