Anarka Couffaine is the Juleka and Luka Couffaine's mother. In "Captain Hardrock", after Roger banned her from playing in the National Music Festival, she is akumatized by Hawk Moth into Captain Hardrock, a music pirate supervillain.
Anarka has long grayish-green hair braided down her back and sky blue eyes.
She wears bright red glasses and a black coat with a gold trim that reaches her knees, over a light pink top and light blue jeans. She also wears heeled brown boots that go halfway up her calves.
She wears earring with alternating aqua and red spheres, and a variety of bracelets and bangles. She also wears three rings on every finger except for her ring finger on her right hand. Anarka also has an indigo headband with a violet flower positioned in the center.
As Captain Hardrock
Captain Hardrock has long red hair spiked upwards, and golden eyes. The upper half of her face is covered with a black mark edged with dark red, and she wears a black bandana with a white spiky-haired skull on the front, along with gold circular earrings.
She wears a body suit that is red from the collar to the chest and black from the chest, the color separation looking like flames. The suit includes three yellow buttons vertically on the lower body, three golden spikes horizontally over each knee, and a golden patch above each hip. She has two black belts, one going around the body diagonally and the other wrapped around the waist, that have golden buckles. Over her suit, she wears a black captain jacket with golden inner lining, golden spikes on the shoulders, golden edges, and golden buckles on the sides. Black fingerless gloves with golden edges around the upper holes cover her arms up to her elbows. Her knee-high boots that end below the knees are black and red in a flame-like pattern with black soles, golden heels, black inner lining, and black stripes with golden spikes above the ankles.
For a weapon, she carries a cutlass with a black handle, three thin red stripes on and near the pommel, and a blade with jagged black edges that goes from red at the handle to white at the tip.
Anarka sounds and talks like a pirate. She believes that chaos and disorder can be a good thing, which is shown when she tells Marinette that she likes to keep her houseboat messy. Despite this, she knows when they are not, such as not allowing a metallic statue anywhere near the boat's compass, knowing metal makes it goes crazy and thus useless. She also believes in freedom, even naming her houseboat “Liberty.” When Roger Raincomprix orders her to keep her music’s volume down, Anarka stands her ground, believing that she should be free to be as loud as she wants for her concert. After she is deakumatized, however, she realizes that she should obey the rules sometimes and keeps her volume down.
As Captain Hardrock, her desire for freedom increases to the point where she wants to blast her music across Paris and ruin the other concerts so that she’ll be the only one heard. When the passengers of her ship refuse to play music for her, she gets mad and imprisons them. She also doesn't consider herself as her kids' mom anymore, and has no remorse in taking them prisoners when they refuse to obey her.
As Captain Hardrock
Her houseboat, the Liberty, has become a seemingly indestructible living ship that can fire chains on command to ensnare Captain Hardrock's foes, as well as blast lasers, and it's cannons fire cannonball-shaped speakers which seem to act as white noise machines. The compass also points to whatever direction Captain Hardrock orders.
For a weapon, she has a microphone which doubles as a laser cutlass.
