Cosmo Julius Cosma is one of the main characters on the show. He is one of Timmy Turner's fairy godparents alongside his wife, Wanda.
Cosmo is Timmy Turner's fairy godfather. Along with his wife, Wanda, he was tasked with making miserable Human children happy by granting them wishes and keeping them safe. Unfortunately, due to Cosmo's immense stupidity, he often times puts Timmy in danger with his wishes, or misinterprets the wording of a wish and grants it wrong, wreaking havoc. Despite his stupidity, and a tenancy to argue with Wanda, he really does love his wife and his godchild. He and Wanda eventually would have a child together named Poof.
His head is full of grape jelly, according to Fairly Odd Baby. He is the youngest son of the overprotective Mama Cosma, who does not approve of his marrying Wanda Fairywinkle in the least bit and has often tried to separate the two. He was once the last Fairy ever born, until Poof came. He apparently was in a band where he played the electric triangle, though tomatoes were thrown at him every time he played. He is usually the cause behind Timmy's adventures, often misunderstanding circumstances, or agreeing to grant a dumb wish. He will sometimes cause Timmy to realize what has to be done to reverse a wish, but this does not happen often. He keeps a diary, which has all of his deepest, darkest secrets, including the fact that he is afraid of the hunt. He is often the subject of magic from Wanda, who usually does something to him to shut him up, including zipping his mouth, and then encasing him in vanadium. There are countless other scenarios. He is often rather careless, but loves Wanda and Timmy Turner through his destructiveness. It is also noted that even though he sometimes messes up with his magic, it's very powerful, as shown when he was able to accidentally wish away Wanda's wand and make wands in Wishology, which is something that it is said that fairies cannot do when they say that magic cannot wish away magic.his favorite flower is the rose
