A major part of these stories is the supporting characters who either progress the plot or help the series’ main protagonists.

In the series Winx Club, a girl named Bloom is joined by others in her studies at Alfea College. While enrolled at this college, Bloom and her friends hone their skills and their abilities as fairies. The series allows Bloom to meet any characters, from other fairies to mythical creatures, and one such character is a witch from Cloud Tower, Mirta.

Mirta is unique due to her belief that fairies and witches are capable of getting along, despite the two groups having an ongoing rivalry. This belief eventually leads her to transfer to Alfea college, where she earns the title of a Fairy of Illusion. While she often resorts back to magic, her ability to create illusions from her emotion allows her to continue bridging the gap between fairy and witch.

Many fans may overlook Sid due to his distrusting nature and paranoia, but he does have a nicer side that appears when helping his friends.

Sid’s interest in occult subjects and urban legends is a unique trait in cartoon characters, and his superstitions bring a new level of humorous scenes to the series. Another side of his character can be seen when he’s not around his friends like Stinky or Harold, and this distinction reveals that there is more to his surface-level personality.
