Luka Couffaine, known as Viperion is one of the supporting characters of Miraculous: Tales of Ladybug & Cat Noir.
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.
In "Truth", after Marinette refuses to tell him her secrets, Luka is akumatized and amokized by Shadow Moth into Truth, a three-eyed supervillain that forces people to tell the truth and his emotions form the giant eye sentimonster.
Description
In "Captain Hardrock", Luka and Marinette first met and Luka quickly develops romantic feelings for her.
In "Silencer", Luka is akumatized by Hawk Moth into the voice-stealing supervillain Silencer. Luka even confesses his feelings to Marinette as both Silencer and himself.
In "Party Crasher", Master Fu lends Luka the Snake Miraculous to help defeat the titular akumatized villain, after which he presumably returned it to Fu.
Personality
Unlike his sister Juleka, Luka is a calm boy who has a mixed personality of being playful, charming, mature, and flirtatious. He is empathetic at reading people's emotions and expressing it through music. Luka is very kind and generous, especially towards his friends and family, but also to people he just met as he cheers Marinette up shortly after meeting her. Like Adrien, he is also supportive and encouraging towards others like his sister Juleka. Adrien himself describes him as brave, caring and determined.
Luka seems to be a easygoing and relaxed boy. However, sometimes he can lose his calm if feels that he and mainly his friends are being wronged, like when Bob Roth stole his band's music, dance and outfits and claimed them to be XY's. Despite everything, he tries to retain his cool, only getting really mad when Bob threatened Marinette. According to her, in "Luka as seen by Marinette", he is very intuitive.
As Viperion, most of Luka's personality remains the same like his caring and helpfulness as he tried to save Carapace by taking Party Crasher's attacks. Given his calm disposition, Viperion is focused, observant and not afraid to give suggestions or ideas to others.
As Silencer, his main goal is to make Bob Roth tell the truth regarding the fact he stole the Kitty Section's song as he takes the voices of anyone that could serve his purposes or get in his way. However, he still retains his care for Marinette, as she was the only person whose voice he spared and he reassured her he would make "justice" for her and Kitty Section.
As Truth, he is shown to be desperate to know Marinette's secret, attacking anyone that could possibly know it, like her best friends and her parents. He is shown to get frustrated quite easily, when they keep telling him a secret he already knows. However, he can prioritize other secrets when they have a much bigger meaning to him, like when he made his mother confess to him who was his father, causing him to abandon his search for Marinette's secret to know the all truth.

As a result, he is given a ouroboros bracelet known as the Snake Miraculous, which when worn grant Luka the ability to transform into Viperion, his superhero alias.
As the holder of a Miraculous, Luka is assisted by a small creature resembling a snake called Sass who is a magical being known as a Kwami.

Trivia

- He also shows to be a better user for the Miraculous and it's power, as Adrien wasn't able to beat Desperada after 25,913 times, while Luka was able to defeat her after 4 times. Although an exact number wasn't directly confirmed, it was definitely in a faster timespan in comparison to Adrien's attempts.
- Luka's surname Couffaine is a combination of "couffin" (French for "coffin") and the French suffix "-aine" (meaning "of or from a place"), ultimately meaning "of/from the coffin".

- However, it is actually a pun, as a matter of fact in French it sounds like "acouphène" which means "tinnitus".
