Cosmo has green hair and typically wears a white shirt, black pants, and a black necktie.
Personality and Traits
Cosmo is known for his stupidity and has been responsible for inadvertently causing disasters (examples from various episodes include the violent eruption of Mount Vesuvius on the cities of Herculaneum and Pompeii, the repeated sinking of Atlantis and the destruction of Pluto) since he was born. As explained in "Fairly Oddbaby" Cosmo's ability for destruction is such that when he was born, all fairies were henceforth no longer allowed to have children out of the fear that another potential fairy baby would be as bad as or worse than Cosmo. Although he is very laid back and dim, Cosmo is prone to fits of jealousy and becomes defensive when he sees others flirting with his wife Wanda. He was the youngest fairy until Poof was born and, though he was considered an only child in earlier episodes, has a brother named Schnozmo that debuts later. Running gags in the show have Cosmo being tortured by objects and having crushes on other women. In a later episode, his family name is revealed to be Fairywinkle-Cosma.
