Luka Couffaine

"Music is often simpler than words."

- Luka

Luka Couffaine 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 threatened Marinette after she accused 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 "Party Crasher", it's revealed that Luka is the occasional holder of the Snake Miraculous. When the Miraculous is inhabited by Sass he becomes Viperion, a snake-themed superhero.

Physical appearance
Luka has aqua eyes and medium-length black hair that has dyed teal blue tips, light blue eyes, pale pink lips and he has a Roman nose.

Civilian attire
His attire includes a white shirt with a black Jagged Stone imprint and black jeans ripped at the knee. He also wears a brown leather bracelet, yellow and orange wristbands, and his fingernails are painted black. He has a sky blue jacket with a navy blue hoodie underneath, as well as black high top converse with multi-colored splotches. He wears a black ring with silver outlining on his left pointer finger and black gauges in his ears.

As Silencer
He has blue skin and wears a pink, black and yellow-ish outfit with a jagged mouth.

As Viperion
He wears a black and cyan suit, appearing to be slender and muscular. His suit has a snake texture along with the same kind of underbelly like a snake and has cyan colored mask around his eyes. His eyes also change from aqua to green as does his hair highlights. His weapon appears to be a lyre.

As Luka
Unlike Juleka, Luka is a calm boy who has a mixed personality of being playful, charming, mature and flirtatious. He is skilled at reading people's emotions and expressing it through music.

Luka is very kind and generous, especially towards Marinette Dupain-Cheng by cheering her up in "Captain Hardrock". In the episode "Frozer", Luka seems to be a easygoing and relaxed boy as he kindly helps Marinette tie her laces on her figure skates and doesn't react when she kisses him on the cheek.

However, in "Silencer", Luka shows that sometimes he can lose his calm, happening when he feels that he and mainly his friends are being wronged, like when Bob Roth stole Kitty Section'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.

As Viperion
As Viperion, Luka is caring and helpful as he tried to save Carapace by taking Party Crasher's attacks.

As Silencer
As Silencer, Luka's 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 and love 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 a civilian
Luka is excellent at playing his guitar and creating melodies through people's emotions. In "Frozer", he is also good at ice skating and fairly strong as he can lift Marinette Dupain-Cheng with ease.

As Silencer
As Silencer, Luka can steal people's voices by touching their lips with his two fingers and making a shushing motion; the voice will then escape from the person as a jellyfish-like entity. Once their voices are out, he can store them inside his mask and then he can talk with them using his hands. If his power is used on a Miraculous holder, he can render them virtually powerless unless he says the invocations in their place.

As Viperion
Viperion has much more enhanced skills, such as speed, agility, and strength, and he is almost invulnerable to physical damage.

Second Chance (Viperion's special power) allows him to reverse time and change the outcome of an event, in which the power activates by sliding his finger on his Miraculous.

Marinette Dupain-Cheng/Ladybug
Marinette and Luka first meet in "Captain Hardrock" and Luka falls in love with her at first sight. His mother sends her down to go get him to rehearse with the band. Marinette, who is still bothered by Adrien not coming, and not knowing who Luka is or what he looks like, is startled by him as he opens his eyes, and starts to stutter and mix up her words. He simply teases her playfully about her stuttering but immediately regrets it when she frowns, embarrassed. Reacting to her frown, he apologizes and begins to play his guitar. Her warming up to him as she listens to him play the guitar, he believes that music is "often simpler than words". As a memento, he lets her keep a guitar pick of Jagged Stone that she admires, leaves her in thought, calling her a "funny girl" with a sweet hidden smile. Luka and Marinette exchange sweet glances to each other when Alya Césaire notices Marinette's interest in Luka immediately and teases her about it. He compliments Marinette throughout the time he has with her, helps her escape and hide, and is also worried about her when he talks to Ladybug. Finding out Marinette is safe he calls her "unbelievably brave", and Marinette, as Ladybug, blushes at his comment. Luka spends time with her in "Frozer" when she begins to doubt her relationship pursues of Adrien Agreste offering her support while at the ice rink. Afterwards he isn't fazed when Marinette thanks him by kissing him on the cheek.

In "Silencer", his care for Marinette is so strong that when he witnesses Bob Roth threaten her, he gets angry enough to be prone to akumatization. Even as Silencer, he retains his care for her, sparing her voice and promising to bring justice for her and Kitty Section.

Luka appears to respect Ladybug. When Ladybug unties him in "Captain Hardrock", he asks her about Marinette, to which Ladybug tells him that she's safe and was the one who alerted her to the situation. In "Mayura", he participates in the Parisian rebellion in order to help Ladybug and Cat Noir in defeating Hawk Moth.

As Viperion, like the other heroes on the team he follows Ladybug's lead without question.

However, as Silencer, he gets annoyed with Ladybug interfering with his plans and has no qualms about taking her voice away.

Adrien Agreste/Cat Noir

Nino Lahiffe
Luka doesn't know Nino too well, even though they are both into music, as well as Luka attending the boys only party Nino put together for Adrien, and had stayed behind to help him and the others clear the "aftermath" of it in "Party Crasher".
