Baby Looney Tunes

Main characters

• Baby Bugs – (voiced by Samuel Vincent) He is indicated to be the oldest of the babies, which makes him their official leader. His leadership however does tend to cause tension, especially with Lola and Daffy.
• Baby Tweety – (Also voiced by Samuel Vincent) The youngest and the smallest of the gang. Depicted as the brainstormer, because he comes up with ideas when the others are fresh out of them. He is very sensitive about his small frame (which he must overcome in most episodes centered around him) and curious about what he encounters.
• Baby Daffy – (Also voiced by Samuel Vincent) He is second in the lead after Bugs. Often, he always wants his personal gain. When he does not get what he wants he believes he is treated unfairly, not noticing the inconvenience inflicted on the others. But half the time he does show and mean good intent.
• Baby Lola – (voiced by Britt McKillip) Sometimes, she takes charge. Her independence is greater than the others and she has more boyish tendencies than the other girls.
• Baby Taz – (voiced by Ian James Corlett) As much as Taz is well behaved, he often mistakes various objects for food and sometimes breaks things with his spin. He has a sense of fun which exceeds all the others. He is also more cheeky, crying for when things go wrong or when they don't go the way he wants them to.
• Baby Sylvester – (voiced by Terry Klassen) The tallest of the babies, not counting Bugs and Lola's ears. At times, he is shy and anxious, and he makes an easy target for Daffy to hoax and trade with. He is rarely seen using his claws. He likes to get attention from Granny more than the others. Sylvester is afraid of lightning and he hates pickles.
• Baby Melissa – (voiced by Janyse Jaud) She often sticks with Petunia; the two were abruptly added to the main cast in the middle of the first season. She is a highly practical and creative sort with a friendly personality, but at times she can be a control freak and get on the others' nerves.
• Baby Petunia – (voiced by Chiara Zanni) She often sticks with Melissa; the two were abruptly added to the main cast in the middle of the first season. She is more intelligent than the other babies with insatiable curiosity. In the episode "Let Harder They Fall", she is no longer wearing diaper anymore like other babies but by the time Petunia wears yellow, frilly training underpants with a white bow in the middle and "Petunia the Piggy Bank", she learned to save money.
• Granny – (voiced by June Foray) She offers professional love and care for the babies to keep them happy. Being the only adult in their lives, the babies are fascinated and inspired by her intelligence, wisdom and ability to overcome problems when they arise with ease.
• Floyd Minton – (voiced by Brian Drummond) Granny's nephew. Sometimes he is overwhelmed by the responsibility he takes on the babies, but he is determined never to let Granny down. He often keeps an eye on one of the individual babies in each episode during Season 2.

Other characters

All of the other Looney Tunes characters except Speedy Gonzales have made cameos over the course of the show's run, mainly as guest spots or during songs. Penelope Pussycat is only shown in still portraits. For example, she can be seen in parody paintings of Caesar Augustus, American Gothic and Cupid during the "Vive Le Pew" song at the end of the episode "The Dolly Vanishes/Duck's Reflucks". Also, there is Baby Marvin in "War of the Weirds".
