Nino Lahiffe

Nino is Adrien's best friend and a student at Collège Françoise Dupont. In "The Bubbler", Hawk Moth infects him with an akuma to transform him into the Bubbler, a bubble-wielding supervillain.

Appearance
Nino is tall, with short dark brown hair, brown skin, and golden brown eyes.

He wears a plain red cap atop his head. He also wears black-rimmed glasses. A pair of dark gray, blue, and orange headphones are found around his neck. He wears a short-sleeved blue shirt with a eye design on the front, having a black pupil, white sclera, dark gray upper eyelid with lashes, and light blue lower lid. Additionally, he wears lime green, pink, red, blue, and yellow bands around his right wrist, blue-gray jeans, and red and white high collar shoes with a white knight design on the tongues.

As the Bubbler, he has light blue skin, reddish-brown eyes, and black circles around his eyes, along with a black spot above his left eye and a black spot below his right eye. He wears a bright red, blue and yellow body suit, with many parts of the suit being rounded like attached bubbles. Around his head, he has a red helmet that features a red antenna on top with a red sphere. Also, he wears black boots, black elbow-length gloves with pink knuckles, and black pants. On his chest, an eye-like black and white circle with two dark gray tubes attached. The tubes connect to Bubbler's red, yellow, and blue bubble container, where he puts his bubble wand when he isn't using it. The bubble wand has a blue handle and a yellow head with a long, oval hole.

Personality
Nino is fun-loving, enthusiastic, friendly, and compassionate. He enjoys being a DJ at parties and hanging out with friends. He is described as "a caring friend with a strong sense of right and wrong." Noticing when someone, like Adrien, is upset, he does what he can to comfort them or cheer them up. If he has a vision for something, he stays dedicated to it, sometimes rather stubbornly. But if things don't go in the fashion he wants them to, it exasperates and upsets him. He is more than willing to argue for his point, though he is able to change his opinions on situations or particular people. Nino becomes frustrated if he sees something that he considers unfair, like when Adrien's father won't allow Adrien to have a birthday party. However, he doesn't hold grudges for long, and whether by choice or not, he will help others when they they ask for it.

As the Bubbler, he becomes less caring and more aggressive, being much wilder and louder than normal. Although one of his intentions is to let Adrien have the birthday party that he never gets, he also despises adults and uses his powers to get rid of them. His hatred can extend to his peers if they defy his orders. His rage proves to even be an issue for Hawk Moth when he traps Ladybug and Cat Noir and sends them into the sky instead of taking their Miraculouses.

Adrien Agreste/Cat Noir
Adrien is Nino's best friend. They enjoy hanging out with each other, and they sit together in class. Aware of Adrien's issues with his father, Nino tries to console and help him. In order to get Adrien a birthday party, he is willing to talk to Gabriel about allowing him to have one, a request which Gabriel coldly refuses. Nino notices that sometimes it's hard for him to get in contact with Adrien, but he doesn't hold it against him or anything else, not blaming him for his father's unkindness towards him. Whenever Nino is stressed about something, Adrien encourages him and is always willing to help him, like, for example, when Nino plans to invite Marinette out in "Animan".

As the Bubbler, he prepares a birthday party for him and forces some of his schoolmates to attend and have fun.

The feelings Nino has for Cat Noir are that of a fanboy, finding him awesome and admiring him. As the Bubbler, he is not pleased with Cat Noir interfering with his plans.

Alya
Nino and Alya appear to be friends. During school in "Copycat," he happily agrees to Alya's request if she and Marinette can join him and Adrien to go to the movies. When Marinette isn't around to help Alya find out if Chloé is Ladybug in "Lady Wifi," she gets Nino to help, who, despite doubting Chloé would be Ladybug, assists her. The two don't always get along, however, Nino falling under Alya's fire when he admits to adding a kissing scene to her script without telling her in "Horrificator."

In "Animan," when Nino tries to confess to Marinette the fact that he has a crush on her, he panics and says that he has a crush on Alya instead. After Ladybug put him in a locked cage, where he is stuck with Alya all afternoon, Nino reveals that, after spending time with Alya, he doesn't have a crush on Marinette anymore, finding that he has a lot in common with Alya.

Marinette Dupain-Cheng/Ladybug
Whenever they interact, Nino and Marinette seem to be friends. He answers Marinette's questions about what happened to Alya (who got suspended) during class in "Lady Wifi," and he tells her "good luck" while recording her at parent show and tell in class in "Rogercop." At the race between Alix and Kim in "Timebreaker", they both hold sides of Marinette's banner.

In "Animan," it is revealed that Nino likes Marinette and thinks she is cute. Nino has had a crush on Marinette ever since "Rogercop". However, after Nino spends a whole afternoon with Alya locked in a cage, he affirms that he doesn't have a crush on her anymore. Additionally, while they were in the zoo cage, Alya confesses to Nino that Marinette has a crush on a boy in their class; thus, Nino offers Marinette his help by saying that he will talk to whoever the boy is.

With Ladybug, Nino appreciates her heroism. But when he is Bubbler, he dislikes her ruining his party and messing with his plans.

Chloé Bourgeois
Although aware of Chloé's feelings for Adrien and, as the Bubbler, even helping her by playing slow dance music at the birthday party, Nino dislikes her and her rude, bossy personality. When Alya suspects that Chloé is Ladybug, Nino laughs it off, pointing out that no one as awful as Chloé could be Ladybug. He is also displeased by Chloé for blaming Sabrina of attempting to steal Marinette's diary instead of sharing responsibility for the crime during class president elections.

Normal form
Nino is a skilled DJ, being able to create awesome beats for any party. With his cellphone, he likes to record videos, and, in "Horrificator," he films a movie with it.

As a villain
As the Bubbler, with his bubble wand weapon, he can create giant impenetrable bubbles with various powers and colors.

Purple bubbles can be used to chase and capture people, turning green. Additionally, the Bubbler can use them to project his face and give a message, or stand on them to levitate.

Red bubbles are his offensive attack: he can throw them at his enemies causing a fiery explosion on impact. Additionally, the Bubbler can turn existing red bubbles into swarming green ones that attach to people and morph into a giant green bubble. This is used to catch both Ladybug and Cat Noir in one go.

He's unable to levitate in midair without standing on a bubble, but he can jump very high and fly from one place to another leaving a trail of purple bubbles.

His bubbles cannot be penetrated by limbs and Ladybug's yo-yo. However, the shields Ladybug and Cat Noir create by rotating their weapons offer some protection, the bubbles can be blown away by air currents and they can be burst by Cataclysm and the Miraculous Ladybug.
