Klaus

Klaus is a supporting character of Season 4. He is the father of Roxy and the husband of Morgana. He owns the Frutti Music Bar, where he is a bartender.

Appearance
Klaus has short brown hair, brown eyebrows, gray-blue eyes and a tanned complexion. He has well-defined cheek bones and jawline. He has a well-built body that consists of strong arms and legs along with a very muscular torso.

Civilian
He wears white pants, dark blue and red running shoes, and his shirt with a high collar matches his shoes.

Younger Years
He is seen with a long-sleeved turtle-neck shirt with stripe details and long pants.

New Year's Party
He wears a black suit, with black dress shoes, a gray dress shirt and gray vest.

Personality
Klaus is very protective about anything related to his daughter. At times, he is frustrated by her constant habit of picking up stray pets but he often lets it slide as he is just as compassionate as his daughter for animals; he had befriended a white tiger cub. He is accepting of the fact that Roxy is a fairy.

Klaus either has a bad memory (possible from the memory spell put on him by the Wizards of the Black Circle) or simply has a playful nature as he called the specialists: "Smile", "Brandi", "Rivet", "Booboo" and "Tobias". It is debated whether or not this was a side effect of the memory charm placed on him by the wizards or if he was simply teasing them. One should also note that he remembered Jimmy's name which he introduced himself as, and did remember the Specialists' names later on in the series.

While he is strict at times he is caring, such as when he noticed Riven was down, he offered him a smoothie and tells him that it is guaranteed to cheer him up.

In the comics, he is also shown to be quite romantic and a smooth talker.

Pre-Series
During his youth, he had met and fell in love with Morgana. They soon had a baby, Roxy and adopted puppy Artu. The family were enjoying their time together and Morgana was ready to step down as Queen of the Earth Fairies for their family but the Wizards of the Black Circle's threat forced her to return. Klaus had no idea his wife had been defeated and imprisoned. His memories of her were then wiped out by the Wizards to prevent anyone from daring to rescue Morgana. From then on, Klaus would then raise Roxy as single father.

Season 4
Klaus makes his first appearance in the episode "Love & Pet" as the owner of the Frutti Music Bar. He appears as a single father, raising his daughter Roxy as one of his employees. His bar is very popular with Andy's band performing every once in a while and fancy styles to make it lively and fun. Kind and generous he decides to hire the Specialists as his new employees thanks to their talents, looks and desperate need for a job! It also appears that he hired the Winx girls as well, but this is left unspecified due to their work with Love & Pet. He allows Musa to perform as well.

When Roxy tries to reveal to her father that she is a fairy, Klaus at first suggests she is joking; but it is revealed he is Duman in disguise. The Winx discover the real Klaus captured at the docks and confused as to what is happening. After a brief battle, he witnesses Artu becoming injured, forcing his daughter into a fairy transformation. Even more confused at this point with his daughter being a fairy, Klaus soon accepts his daughter for the way she is.

Through the rest of the season, Klaus is shown being reluctant to allowing Roxy to travel with the Winx in fear she may truly get hurt, but ends up allowing it. He is also aware of Riven's rocky relationship with Musa, and attempts to help him take his mind off of it by reminding him to do his job. Despite this, he truly cares about the Specialists like his own sons.

At the end of the season, it is revealed that Roxy is Queen Morgana's daughter, and the Morgana is therefore the wife of Klaus. It is revealed the two had married long ago and had Roxy together while Morgana stayed on Earth disguised as a human. However, when Morgana was forced to leave Gardenia to return to protect her kingdom, she was sealed by the Wizards in Tir Na Nog, and all memories of her were wiped from the minds of all friends and family members as a result of the Wizards' negative magic, and Klaus was left to raise Roxy on his own. In the last episode, Morgana returns Klaus's memories and the two reunite; making their family complete with Roxy.

Season 5
In "The Rise of Tritannus" he is seen bartending as usual at the Frutti Music Bar. The bar is full of people as the Winx are holding their benefits concert.
