Carapace

Nino Lahiffe, a.k.a. Carapace, (voiced by Ben Diskin) is a student in Miss Bustier's class at Collège Françoise Dupont and Adrien Agreste's best friend. He also is a DJ and the head of the school radio.

In the Miraculous: Tales of Ladybug & Cat Noir episode, "The Bubbler", when Nino becomes frustrated with adults after failing to convince Gabriel Agreste to allow Adrien to have a birthday party, Hawk Moth akumatizes him into Bubbler, a bubble-wielding supervillain.

Starting from "Anansi", whenever Nino receives the Turtle Miraculous from Ladybug and commands Wayzz to inhabit the Miraculous, he becomes Carapace, a turtle-themed superhero who helps Ladybug and Cat Noir "during particularly difficult missions" in the second season.

In "Mayura", during the fight with Scarlet Moth, due to grief caused by watching Rena Rouge fall victim to an akuma, Carapace is in turn akumatized into Shell Shock, a turtle-themed supervillain.

In "Oblivio", due to his and Alya's embarrassment at being caught playing the Super Penguino game together, they are both akumatized into Oblivio, a memory-erasing supervillain.
