Coltrane (voiced by and modeled after Corbin Bleu) is a friend of Jeremy Johnson. He is the bassist in his band, Jeremy and the Incidentals, and a love interest to Stacy Hirano. He was first seen when he, along with Jeremy and the band's unnamed drummer, performed at the Summer Festival, during which they were briefly transformed into a punk rock version of themselves by Dr. Doofenshmirtz's Ugly-inator. ("The Best Lazy Day Ever")
Coltrane appears to be a love interest for Stacy. During the end credits of "The Best Lazy Day Ever", while performing Do Nothing Day, they can be seen smiling at each other in a way very similar to how Candace and Jeremy are smiling at each other in the same scene.
The two later formally introduce themselves to each other in "The Baljeatles". They immediately show mutual attraction to each other, including dancing with each other during "Somebody Give Me a Grade" and holding hands afterwards.
He also said he would teach Bass to her.
He is great friends with Jeremy Johnson. He may be like what Stacy is to Candace, a best friend. He is seen with Jeremy in "Let's Take a Quiz" and "The Baljeatles". He is also seen at Jeremy's party in "De Plane! De Plane!
In "The Best Lazy Day Ever" and "Let's Take a Quiz", Coltrane wore a red hat, t-shirt and shorts. His character layout and appearance was changed in "The Baljeatles" so that he would look more like his voice actor, Corbin Bleu.
