Sparky (The Fairly OddParents)

Sparky is a fairy dog that joined Timmy Turner and his fairy family in Season 9. He was introduced on the Season 9 premiere episode, "Fairly OddPet", becoming the second addition to the show's main cast, after Poof, in 2008. However, due to bad reception by the public, Nickelodeon decided to not have the character back for Season 10. Sparky was voiced by Maddie Taylor.

Bad Qualities

 * 1) He is a completely unnecessary character to be in the show. Why would Timmy need a dog?
 * 2) He is pretty dumb and mostly present as comic relief. Don't we already have Cosmo, Timmy's dad, and/or Mr. Crocker for that purpose?
 * 3) He causes a lot of trouble around his owners.
 * 4) He also gets Timmy in trouble at school by eating his homework.
 * 5) In Fairly OddPet, he leaves Timmy to almost die in a plane crash and destroys Dimmsdale by digging holes everywhere.
 * 6) He is a failed attempt for Nickelodeon to boost the show's ratings. Nickelodeon tried to do the same exact thing a second time by replacing him with Chloe Carmichael and that, too, also flopped miserably.

Good Qualities

 * 1) He at least isn't a Gary Stu unlike Chloe Carmichael (Mary Sue).
 * 2) His design is passable, although it has off-putting white lines.
 * 3) He did help Timmy at times and unlike Chloe Carmichael, he never stole the spotlight from Timmy, despite season nine being more focused on him. There were also some episodes where he was either a minor character or completely absent.

Trivia

 * 1) Because of the negative reception he had, Sparky did not return in Season 10 and was entirely written out of the show.
