Denzel Crocker (seasons 9 and 10)

Denzel Crocker, also known as Mr. Crocker, is one of the main antagonists in The Fairly OddParents and is voiced by Carlos Alazraqui.

Sadly, he has received massive amounts of flanderization from Season 9 until the show's cancellation.

Why He Deserves An "F" Now

 * 1) He went from a crazed teacher wishing to prove to the world that fairies exist, into a carbon copy of Mr. Turner.
 * 2) He is also an incompetent and idiotic villain as well, most notably in the episode "Return of the L.O.S.E.R.S.".
 * 3) *Speaking of which, in its sister episode, "The Fair Bears", he immediately believes Chloe Carmichael into thinking that the Fair Bears are fairies because, you know, Little Miss Perfect knows best, right?
 * 4) His backstory as a child of how he originally lost his fairies has been completely changed. On that note, his child self went from a passionate, loveable, and brave kid who wanted to help others into an egoistic brat, much like Timmy Turner has become.
 * 5) Like Cosmo and Mr. Turner, he became a 'too dumb to live' type character.
 * 6) Along with Mr. Turner, he is severely overused because he became the creator's pet for cheap laughs. This is especially a problem with Vicky's three centered episodes.
 * 7) He acts like an immature and jokester of a manchild similar to Mr. Turner in several episodes such as "Desperate Without Housewives", "Animal Crockers", "One Flu Over the Crocker's Nest", "Married to the Mom", "Crockin' The House", "Goldie-Crocks and the Three Fair Bears", etc.
 * 8) He seems to be the only villain aside from Foop who the writers always favored over almost all the other villains.
 * 9) His gags have gone from entertaining to irritating.
 * 10) His character slowly started to derail beginning in Season 7, with Season 8's "Timmy's Secret Wish" marking the true beginning of his character's downfall. In that episode, he helps Timmy return to Fairy World, only for him to be in the background and make running jokes for the remainder of the episode.
 * 11) *Speaking of which, the episodes "Timmy's Secret Wish!", "When Losers Attack", "Scary GodCouple", "A Fairly Odd Summer", "Return of the L.O.S.E.R.S", "Clark Laser", and "Crockin' The House" have him socially interacting with Foop in a rather positive and friendly matter, despite the fact that he is an anti-fairy, which is almost the same as the regular fairies. This is a totally missed opportunity for Mr. Crocker to confront and hunt the anti-fairies (and even the pixies to an extent) in general, which could have allowed for a more creative, interesting, and ambitious plot.
 * 12) In Season 10, his original personality is completely gone with the exception of "Fairy Con" and "Chip Off the Old Crock!".
 * 13) *Speaking of the latter episode, we are introduced to Kevin Crocker, his nephew, who is more-or-less a miniature version of Denzel himself. Don't we already have his mother for that?
 * 14) *Kevin's high-pitched voice when compared to Denzel is also annoying to listen to as well.
 * 15) The humor surrounding him living with his mother is also exaggerated in some episodes, such as "Booby Trapped".
 * 16) Despite being the "main antagonist" since Season 7, he is mostly just written and portrayed as a filler or comic relief/running joke character (or otherwise, an incompetent idiot who constantly screws up his plans to catch fairies properly), much like Mr. Turner, and his original personality is only when the plot demands it.
 * 17) His ears being located on his neck still makes him look rather hideous in appearance, especially if close-up. We know it's meant to represent his personality, but still.
 * 18) His famous catchphrase "FAIRY GODPARENTS!" is barely used anymore.

Redeeming Qualities

 * 1) He was a better villain in the first six seasons, although it is questionable whether he was in character or not in Seasons 7 and 8.
 * 2) Occasionally, he has his original personality and hilarious moments.
 * 3) He is still a tragic character deep down due to the events of "The Secret Origin of Denzel Crocker" from Season 3, which makes his flanderization even sadder.

Reception
His flanderization and excessive screen time are one of the main reasons why Seasons 9 and 10 are poorly received by fans and critics alike.
