Mac: A bright, creative, sorta shy nine-year-old boy who lives with his mom and older brother Terrence.
He has an older sister Justine whom is in college. Mac almost always knows what to do when there is a problem and how
to punish a person when they are bad. He becomes Indigo Dragoness' sidekick under the name "Draco" with a costume to boot
and a series of grappling hooks, small explosives, the arrows that burn, sting, zap & freeze on contact which Indy
handed down to him and a squirtgun filled with acid, glue, oil & some other liquids. He, Bloo, Coco, Wilt,
Eduardo, Frankie & Goo know Indy's secret identity.
Blooregard Q. Kazoo: "Bloo" for short, he's Mac's best friend. A wise-cracking, obnoxious & selfish blue door-shaped
blob. He was left at Foster's after Mac was forced to give him up, but he's the only Friend whom isn't up for adoption
as long as Mac visited every day. He very often gets into trouble because of his mischievous mind and attention-craving
ego. Bloo is the self-appointed member, more than once, he's tagged along to kick Raptor butt, especially when
he wasn't invited. He wears a red mask, white cape & a big backwards "B" on his chest and make-believes he's
a superhero. Many times, he's helped & other times he's gotten in the way.
Wilt: A tall, red, imaginary friend with a stubby left arm and a crooked eyestalk. Wilt enjoys basketball and is
generally very easy-going. He will always aid a friend in small tasks, prides himself on rescuing abandoned friends, and sometimes
helps Frankie around the house. His defining aspect is his sense of fair play and good sportsmanship, which he applies to
every part of life he can. He was adopted by Sara, but she was forced to give him up since the landlord doesn't allow Imaginary
Friends. So, Sara visits him every day just like Mac does with Bloo. Wilt & the other Friends whom know Indy's secret
identity very often help kick Raptor butt, even Bloo (sometimes).
Eduardo: Eduardo is an imaginary protector friend with a Spanish accent and speaks "Spanglish" (combo of English
& Spanish). He may seem scary looking, but he's actually a coward and one of the kindest, gentlest Friends around. But
in spite of his almost constant state of terror, however, he is incredibly strong and can be trusted to come to his friends'
rescue whenever they are truly in trouble.
Coco: A wacky friend whom is a combo of a bird, plant and airplane, she can only speak & write
the word "coco" at various speeds and with different emphasis. Everyone else understands her without any apparent
difficulty. Her favorite drink is cocoa which sometimes causes confusion. She can also lay colorful plastic eggs that
will have virtually any item inside them; however, she won't always lay an egg carrying something that the others need.
Frances "Frankie" Foster: Madame Foster's 22-year-old granddaughter, she cleans & cooks around the House. She
is pressured by Mr. Herriman into doing more chores than usual, but doesn't enjoy it, and thinks of herself as "punk
rock." She is good-hearted, hard-working, caring & a great person in general. She's like a big sister to the residants.
Mr. Herriman: Mr. Herriman is a giant imaginary rabbit created by Madame Foster herself, when she was a child. He serves
as the president of the home, and expects the inhabitants to follow his rules (no matter how ridicules many can be). He is
very formal and well-mannered, which leaves his tolerance for Bloo lacking in most regards. He isn't aware of Sara's alter-ego
nor does he know Mac & the gang fight crime & Raptors.
Madam Foster: The founder of the foster home. She is elderly, but she has a lot of spunk and loves to play tricks
on others. Her imaginary friend is Mr. Herriman, whom she imagined when she was a child and never gave up. It sometimes appears
that she finds out Indy's secret identity, but no one's sure.
Goo: Goo is an African-American girl, she's a friend of Mac who named herself Goo Goo Gaga when she was a baby because
that was all she knew how to say. Her nickname (just to make things simpler) is Goo. Goo has an over-active imagination and
has imagined over 600 friends! At first she was a nuisance to Foster's because she over-populated the place but now her
mission is to find homes for all the hundreds she imagined. The fast-talking, kinda wacky Goo only imagines new friends
in dire emergencies.
Cheese: A pale yellow Imaginary Friend, at first Mac thought he created him when he woke up one morning to find Cheese
in his bed. But it turns out, Mac's neighbor, Louise is his creator and Cheese likes to wander off. He likes chocolate
milk & cereal even though, Mac said at one time he was lactose intolerant. He is annoying & dim-witted and calls
many by the wrong species, he is seen as a nuisance umong Foster's and the Ex-Dino HQ.
