The Pac-Man video games:
- Breakthrough Hit: For Namco. Pac-Man is their mascot because of this.
- Fan Nickname: "Ghosts" for the enemies chasing after Pac-Man; Namco has always simply referred to them as "monsters." The Atari 2600 version does call them ghosts in the manual, however. The TV show confusingly combines both names, calling them "ghost-monsters".
- Interestingly enough, one of the cutscenes shows Blnky having his coat torn off by a nail, showing skin underneath, implying, yes, he's a monster.
- Similarly, the big round dots that Pac-Man eats to turn the tables on the monsters/ghosts/ghost-monsters "Energizers" in the arcade. The LP record "The Amazing Adventures of Pac-Man" expands on this by calling them "energizer dots". They are "Power Pills" in the Atari versions, "Power Pellets" in the cartoon, which is actually closer to their official Japanese name: "Power Esa" (lit. "Power Food"). Moreover, Super Pac-Man officially refers to them as "POWER" pellets.
- Ascended Meme: In the 3D games, they're now ghosts. It's sometimes implied that they're not ghosts, but living and made of flesh.
- When Pac-Man has eaten enough dots, Blinky goes faster. Fans call this "Cruise Elroy", but no one seems to know why.
- Marth Debuted in Smash Bros.: Despite Namco preferring to not speak about the unauthorized Bally Midway games (with the exception of Ms. Pac-Man, which was made official thanks to its success), that didn't stop their characters from appearing in official Pac-Man games. Japanese players would think that Junior got his beany propeller hat from Pac-Man 2, when he actually got it from Jr. Pac-Man, his starring role. There's also Professor Pac's appearance in Pac-Man World, when he originally came from Professor Pac-Man, minus the mustache.
- Port Overdosed: Pac-Man and Ms. Pac-Man are two of the most widely ported games ever made, right up there with Space Invaders and Tetris.
- Prop Recycling: The Galboss from Galaxian is one of the fruits.
The 1982 Pac-Man cartoon:
- The Danza: Susan Silo played Sue. Likely either an inversion or a coincidence, as the name "Sue" had been used for a ghost in the Ms. Pac-Man video game (although it was simply Clyde from the original with a different name).
- Hey, It's That Voice!:
- The hero is Beegle Beagle and Autocat; his wife is a cast member from Love American Style; the villain is Uglor from Space Stars; the blue ghost is Clamhead from Jabberjaw, and the red, pink and purple ghosts are characters from CB Bears.
- Pac-Man's cat is Optimus Prime and his dog is Megatron. And once again (or rather, once before), they're in conflict. Only this time, Peter Cullen voices the mean one.
- The second season had Garfield and (the first animated voice of) Peter Venkman as Super Pac-Man and Kid Comet was Pac-Man's bike-riding cousin, PJ (a.k.a. Pac-Jr.).
- Keep Circulating the Tapes:
- Despite airing in 1982, the Hanna-Barbera series saw no VHS or DVD releases until January 2012, when the first season was released on DVD. The second season was released in September that same year. Both are available as manufacture-on-demand DVDs from the "Warner Archive" program, although they can also be bought via Amazon, eBay, and various other Internet auction sites.
- In the 1980s, there actually were a number of VHS releases for the series...outside America.
- Recursive Adaptation: An arcade video game called Pac-Land was released in 1984, which was a side-scrolling platformer that was clearly based on the cartoon. Inky's lazy eye and Sue's purple cloak and eyes survived into the design of the monsters in Pac-Mania. But Blinky retains his speed and aggressiveness, whereas in the cartoon he was an asthmatic coward. In the Pac-Man World games, however, the cartoon is mostly forgotten. There are only four ghosts, and Pinky is now female.
- However, for some time after the release of Pac-Man Arrangement, Blinky's and Clyde's names were swapped around for some time, making Clyde the red, more aggressive, ghost and leader of the gang, and Blinky the orange and more laid-back ghost. This continued even into the second and third World games. Whenever or not this could be considered a homage to the cartoon or simply a mistake on Namco's parts is up to the viewer.
