Characters

Main characters

• Heitor Villa-Lobos (voiced by Arthur Berges) – The protagonist of the series. Heitor is the guitarist, vocalist, main songwriter and the leader of the Under-Undergrounds, and also the only human member of the band. Heitor was the guitarist in an Earth band called "Blitz Creek Bop", but after being replaced and expelled from it, he accidentally fell into an open manhole, landing in the Underground World. He later joined the band Under-Undergrounds.
• Layla Bach (voiced by Bruna Guerin) – The co-leader of the Under-Undergrounds, owner of the garage where they rehearse and one of the founders of the band. She is the keyboardist, vocalist, and only girl in the band. Layla is a pink-skinned mutant who has a pair of antennae on top of her head. Layla is also secretly in love with Heitor, revealing this secret only to her pet.

• James Marshall (voiced by Robson Kumode) – The second guitarist in the Under-Undergrounds, after Heitor, and the son of Ozzy. James is the last to join the band, becoming a member of the Unders soon after the break-up of his previous band, "Attack 51".
