Played by Lucas Cruikshank.
- Alliterative Name
- Anti-Hero: Calling him "heroic" is a massive stretch, given that all his actions are driven by pettiness and/or bizarre emotional impulses. He gets more heroic in the third movie, though.
- Abhorrent Admirer: To Judy.
- Ambiguous Disorder
- Book Dumb
- Babysitter from Hell: To Kevin in "Fred the Teenage Sitter".
- Bratty Half-Pint
- Break the Cutie
- Brick Joke: When the Ultra Momma calls Fred Frederick he asks "who?", because as revealed in the second movie his name is actually short for Ferdinand.
- Cloudcuckoolander: He has medication for this, but it doesn't seem to... you know, work. When Fred lost his medicine, it became worse.
- The Cuckoolander Was Right: Turns out Devlin really was a vampire. Or at least he doesn't cast a reflection.

- The Ditz
- Did Not Get the Girl: At the end of the first movie Fred and Judy apparently do end up together, but in the second movie it's said they broke up almost immediately. In "Fred is Back" they actually end up living together as adults, but Judy refuses to allow Fred to call her his girlfriend.
- Incidentally the original ending written for the film invoked this trope, with Fred realizing his friendship with Bertha was more important than his obsession with Judy, but the network didn't like that ending.
- Dreadful Musician: Fred thinks he's a great singer, but he really isn't.
- Emotional Regression: On Nickelodeon.
- Evil Counterpart: Evil Fred
- Flanderization: Inverted with The Movies, and for good reason: an entire two-hour movie where Fred talked in an incredibly annoying high-pitched, fast-paced voice would get old REAL fast. (He's still pitch-shifted, but not as much.)
- Future Loser: In "Fred is Back" we see that the only job he could get is working nights at a funeral home.
- Friend to All Living Things: Fred actually gets along nicely with Sparky the stray dog, the neighbourhood squirrels and the cat with rabies.

- Tied Up on the Phone
- Teens Are Short: Averted. In fact, by the time "The Show" rolled around Lucas Cruikshank was taller then all of the adult actors.
- Undercrank: How Fred gets his high voice and fast movement.
- Your Size May Vary: Fred is normal-sized in Fred Goes Grocery Shopping Feat. Annoying Orange, but is shrunk down to Liam the Leprechaun's size in Annoying Orange: vs. FRED!!!
- Unreliable Narrator
- Unsympathetic Comedy Protagonist
- Unusual Euphemism: "WHERE'S MY HACKING MEDS?!"
- Vomit Indiscretion Shot

The girl next door whom Fred has a crush on. Played by Pixie Lott
in the movie, Lucas Cruikshank on youtube, Loraine Newman in "It's Fred" and Jennifer Veal in "Fred is Back"
- Put on a Bus: The Nick franchise stopped using the character when they could no longer use Pixie Lott in the role, rather than just replacing her like they did Bertha. We never get a full explanation as to where she's gone though, just that she broke up with Fred.
- Spooky Séance: Holds one in an attempt to communicate with her dead grandmother.
- Suspiciously Similar Substitute: Holly in "Fred: the Show".
- Took a Level in Kindness: In the the first film at least. On the online series, she was rather rude and hated Fred.

She did seem concern for him when he ended up embarrassing himself at her party and actually tried to stop Kevin from teasing him.
