Dappya Men (だっぴゃ)
Voice: Makoto Ataka
These aren't really Urusei Yatsura characters exclusively, as they debuted in Katte na Yatsura but they've made more appearances in the series. These are little fish aliens dressed in spacesuits with funny high-pitched voices. Their name comes from the fact that they end every sentence with "Dappya!" The Dappya are a running joke on the show and the manga. They pop in and out of the screen at random, narrate and make commentary or just stand there as extras in the show. They often substitute in the place of a background character.

Has overwhelming control over manipulation of dreams into reality, but his dreams almost always turn to nightmares. His cohort is the pig-like Baku, which to my recollection is an actual mythological creature which is said to eat dreams.

Kosuke Shirai (白井コースケ)
Voice: Kappei Yamaguchi (OVA), Shinya Takahashi (2022)
One of the high-school guys in the manga often seen hanging around with Ataru. He's hot for Lum, just like every other guy in the school. Kosuke is essentially "Perm" in the anime, though at times fans think of them as different characters. "Kosuke" (specifically, not Perm) appears in the final OVA "The Obstacle Course Swim Meet". It's important to note that in the manga, the characters of Lum's Guards only existed for the first couple of volumes. Kosuke, along with a few other indistinguishable classmates filled the need for average high-school students as extras. However, Kosuke is the only one who actually goes beyond being a simple stock character. He does contribute something to the story on many occasions. As for what kind of person he is, it's hard to say. He seems like an ordinary student. A bit taller than most kids, somewhat athletic, reasonably popular.

Mrs. Mizunokoji is even more powerful than Asuka, yet also highly intelligent. She can even do the "angry big-head" technique (which Soun Tendo from Ranma ½ later perfected). Of course she never apears outwardly angry because her face is unchanging like a china doll's. The smile on her face and vacant stare never changes. She tries to raise Asuka to be an ideal lady, but things keep going wrong, much of which she blames on Tobimaro. Like all members of the Mizunokoji family she has starry eyes.
