Foster's Home for Imaginary Friends/Characters

Here be the Fosters Home for Imaginary Friends characters and the tropes they embody.

Mac
A creative, smart, and very warm-hearted eight-year old. Bloo is his imaginary friend.


 * Absentee Actor: It is possible that his voice actor (Sean Marquette) was busy with something else during the making of the episode Pranks for Nothing.
 * Adorably Precocious Child
 * Author Avatar: Creator Craig McCracken based Mac on himself as a child.
 * Adorkable
 * Badass Adorable: He doesn't "fight" often, but when he does....
 * Big Eater: Only when it comes to sugar.
 * Birthday Hater: With a twist; Bloo giving him surprise birthdays on almost any day except the actual day of his birthday (with one exception), he's grown something of a hatred towards them. It's mainly because he's put in embarrassing situations.
 * Break the Cutie: If Bloo is separated from him. Even if Bloo causes his most woobie-ish moments, he becomes an even bigger woobie.
 * Cheerful Child
 * Chivalrous Pervert: The pervert part is implied, the chivalrous part is clear-as-day.
 * The Cutie
 * G-Rated Drug: NEVER give Mac sugar. Seriously.
 * Intoxication Ensues
 * Heroes Want Redheads: His crush on Frankie.
 * The Messiah
 * Nice Guy
 * Only Sane Man: This trope, however, is wonderfully averted if he eats too much sugar.
 * Out of Focus: Not in the show, but in the merchandise. Whenever merchandise of the series is released, expect Cheese to take his place (except for one shirt with both him and Cheese on it, and at least he did get a stuffed animal and figuriene of himself)
 * Precocious Crush: His crush on Frankie.
 * Puppy Dog Eyes
 * Red Oni, Blue Oni: The blue to Bloo's red.
 * Savvy Guy, Energetic Girl: Savvy Guy to Goo's Energetic Girl.
 * Shrinking Violet
 * Squishy Wizard
 * Sweet Tooth
 * Vocal Evolution: His voice gets lower and somewhat scratchy after a while, due to his voice actor hitting puberty. This is very noticeable, escpecially when on the DVD Commentary for "Store Wars", you can hear him (the DVD came out during season five) talk against his higher voice in season one.
 * Wise Beyond Their Years
 * Your Size May Vary: In some episodes, he's as tall as Bloo, but in others, he's taller. Justified, as he's eight years old and was probably going through a few growth spurts.

Bloo
Mac's reckless, hyperactive imaginary friend. Mac's complete opposite; however without him, Mac would do everything Bloo says and does.


 * Anti-Hero: Type IV or V, depending on the writer.
 * Attention Whore
 * Big Eater
 * Bratty Half-Pint
 * Heroes(?) Want Redheads: His (very shallow compared to Mac's) crush on Frankie.
 * Flanderization: He started out being very protective of Mac. Then he became a Jerk With a Heart of Gold in season one, more of a Jerkass in season two, and by the later seasons, some fans were wishing that Mac would just leave Bloo already.
 * Jerkass
 * Jerk With a Heart of Gold: In the earlier seasons.
 * Jerk With a Heart of Jerk
 * Hidden Heart of Gold: When he though that  he was devastated, and said nobody else deserved to be him.   he acted like he normally did, and said he didn't miss him at all.
 * Red Oni, Blue Oni: The red to Mac's blue.
 * Schemer
 * Screams Like a Little Girl
 * Send in The Clones: In "Bloo's Brothers".
 * Small Name, Big Ego
 * Unsympathetic Comedy Protagonist

 * Pokémon-Speak
 * The Unintelligible

Eduardo
An imaginary friend resembling a huge, hairy monster with a heart of gold.

 * Cloudcuckoolander: He definitely has his "LOCOOOOOOOOOOOOO!!!!!!!!!!!" moments.
 * Cuddle Bug: Gives (nearly bone-crushing)hugs to people he's worried about.
 * Does Not Know His Own Strength: And with his hugs come complaints of wanting to be let down.
 * Gentle Giant:
 * Cowardly Lion:  Ed's a natural cry-baby, and refuses to go into a suituation unless someone's beside him or he's in a group, and even then he's not going to be happy.
 * Gratuitous Spanish
 * Tom Kenny: Compare Eduardo's voice to say, Spongebob or even The Mayor, and you know Kenny's got range.

 * Literal Minded
 * Mean Boss: Poor Frankie.
 * Nice Hat: His top hat.
 * Tom Kane
 * Why Did It Have To Be Dogs: Has a fear of dogs in "Who Let The Dogs In?", due him to being based on a prey animal. So great is his fear that he even called out "Frankie" instead of "Ms. Francis".
