Sparky (The Fairly OddParents)

Sparky is a fairy dog that joined Timmy Turner and his fairy family in the ninth season of The Fairly OddParents. He was introduced in 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?
 * 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) Every episode that revolved around him, including "Fairly OddPet", are really boring and uninteresting to watch since they were just generic and cliché "Man's best friend" plots. Additionally, his introduction alongside the overall concept of magical animals only added to the plot holes and inconsistences with Da Rules, further breaking continuity. As an example, who were his previous owners?
 * 7) 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 9 being more focused on him. There were also some episodes where he was either a minor character or completely absent.

Reception
Sparky has gotten mainly negative reviews, fans even quitting the show over time as Season 9 went on and because of him. However, it should be noted that there are a lot of fans who like him.

Trivia

 * Because of the negative reception he had, Sparky did not return in Season 10 and was entirely written out of the show.
 * His voice actress Maddie Taylor, who was known as Matthew Taylor at the time of voicing Sparky, came out as a transgender woman in 2016.
