Papa Cosmo

Papa Cosmo Sr. is Cosmo's father (who he bears an incredible resemblance to), the spouse of Mama Cosma and father-in-law of Wanda Fairywinkle-Cosma. He is also the grandfather of Poof.

Character
Many details about Cosmo's father are not known clearly, only that he was turned into a fly when Cosmo got his first wand. It is unknown if he was ever turned back into his fairy form, or if he is still alive, and his exact marital status with Mama Cosma is unknown. Mama Cosma showed a hint of liking Big Daddy in the episode "Big Wanda", which would imply she is single, but that particular relationship is never explored further. It seems unlikely that Papa Cosmo was ever turned back because he has not been seen in any other episode. It is possible that since he was still a fairy, he could still be alive, considering that in "Fairly Odd Baby" it was stated by Wanda that fairies live forever. It is unknown how his relationship was with his eldest son Schnozmo.

It is possible that he left Mama Cosma due to Cosmo's behavior and incidents, (like sinking Atlantis nine times, destroying Pompeii, and others)

Description
Papa Cosmo looks almost identical to his sons, except his hair is virtually identical to Timmy's future daughter Tammy, except for the green coloration and wears glasses.

Background
He is seen in the episode "This Is Your Wish". During a flashback to when Cosmo is a baby, he is shown getting his first wand. He immediately turns his father into a fly, who buzzes away out of the window and is never seen again.
