often followed by Herb and Nicolas, whom she often shows resentment towards, but uses them to her advantage anyway. She was initially part of the gang and knew about Lyoko, but was kicked out after breaking her oath to keep the Supercomputer a secret. Her memories of Lyoko were subsequently erased. She becomes friends with the Lyoko Warriors at the end of the series. Sissi also shows a dislike for her full name, Elisabeth, often making sounds of disgust when it's mentioned. Herb Pichon (French: Hervé Pichon) Voiced by: Bruno Mullenaerts (French); David Gasman (English) An eighth-grader at Kadic and a classmate to the Lyoko Warriors. He is the second-in-command of Sissi's gang, and sometimes even the boss in times of emergency when Sissi proves to be incompetent, as he is the most intelligent member of their group. Herb is also shown to be in love with Sissi, although he doesn't tell her because of her crushes on various boys, most notably Ulrich. He is the second-best student in his class after Jeremy and the two often compete with each other, but Herb is almost always the loser. Herb is also shown to be easily scared off, quick to run away when something troubling happens. Nicolas Poliakoff Voiced by: Carole Baillien (French); Matthew Géczy (English) An eighth-grader at Kadic. He is the third member of Sissi's gang.

He usually only does things when Sissi orders him to, and will otherwise not do much on his own. Nicolas also has also been shown to have a crush on Aelita, although he never acts on it. He can play the drums, and was in the Pop Rock Progressives, a band started by Odd. He is generally more tolerant of and less rude toward the Lyoko Warriors than Herb and Sissi are. In some episodes, it is shown that he has at least some degree of intelligence, as he wrote a script for a performance of Romeo and Juliet. Nicolas is also shown to be as easily frightened as Herb is. Jean-Pierre Delmas Voiced by: Bruno Mullenaerts (French); Allan Wenger (English) The principal of Kadic Academy, who is easily controlled by his daughter Sissi. He can be stubborn and incredibly ignorant at times, especially when members of the Lyoko Warriors are trying
