* CreatorsPet: He dominated the ''MickeyMouse'' series even when he had a series of his own. That mouse can't catch a break, can't he?
** Plus he appeared in two SillySymphonies and a few DonaldDuck cartoons.
* MostAnnoyingSound: His iconic yelp, which quickly becomes insufferable whenever he's in distress ([[ButtMonkey which happens a lot]]). Thankfully toned down in more recent cartoons, where he more stereotypical dog vocalisations.
* NightmareFuel: Plutotopia, why is it so? Well, Pluto in a dream is tormented by a talking cat that addresses him with sarcasm and a suicidal sadomasochist to boot. It shows why cats and dogs should hate each other because this solution is disturbing.
** Pluto's headshot from the original opening titles of the 1940s RKO shorts. It's overly symmetrical appearance can be quite unsettling to first time viewers. Fortunately, a more standard, cheerful title card replaced it later on.
** And, of course, ''Disney/PlutosJudgementDay''.
** "Pueblo Pluto" has the scene where Pluto is trapped in a cactus patch, and starts panicking so much he starts imagining all the cacti coming to life and lunging after him. You ever think a cactus couldn't be freaky-looking? [[http://www.disneyshorts.org/screenshots/1949/469/12large.jpg Think again]].
