Cosmo and Wanda (seasons 9 and 10)

Cosmo and Wanda are two of the six main characters in The Fairly Oddparents and are Timmy Turner's fairies. They've been flanderized since season 9 until the show's cancellation.

Why They Suck In These Seasons

 * 1) Cosmo was originally simply The Ditz and a bit of a Cloudcuckoolander, sometimes dim but still relatively normal, and perhaps strangest of all, he and Wanda seemed to be on an equal level of air-headed and careless intelligence.
 * 2) Wanda was also originally portrayed as being dimmer than Cosmo, believe it or not, then at some point, they shared an equal amount of intelligence.
 * 3) Cosmo became simply JUST the Ditz as opposed to being both that and an average cloudduckoolander.
 * 4) Wanda became simply the wiser one who chastised Timmy and Cosmo whenever they did something wrong, but then all her jokes became nagging.
 * 5) Speaking of nags, Wanda was one to the point where the Barbarian Hero episode had her become the whip cracking Nagules.
 * 6) They both seem to lose their wands a lot in these seasons, particularly in season 10 and depend on Timmy and Chloe to solve the problems on their own.

Redeeming Qualities

 * 1) They are still there for Timmy when he needs them.
 * 2) The show won't be great without them.
 * 3) They still care about Timmy and their son Poof.
 * 4) They are much better back from Seasons 0-8.
