Viperion

Luka Couffaine, a.k.a. Viperion, (voiced by Andrew Russell) is a character who appears in the second season of Miraculous: Tales of Ladybug & Cat Noir. He is the older brother of Juleka Couffaine and a new student at Collège Françoise Dupont, who attracts the attention of Marinette Dupain-Cheng.

In "Silencer", when Bob Roth threatens Marinette after she accuses him of stealing Kitty Section's idea for XY's new song, he is akumatized by Hawk Moth into Silencer, a voice-stealing supervillain.

In "Desperada", after Adrien Agreste gives up being Aspik for not being able to help Ladybug against the titular villain, she gives Luka the Snake Miraculous. When the Miraculous is inhabited by Sass, he becomes Viperion, a snake-themed superhero who helps Ladybug and Cat Noir during "particularly difficult missions" in Season 3.
