His nickname is derived from his hairstyle ("permanent"), he is tall and skinny (though his nameless Manga counterpart had quite a fatter form). Perm often displays the most character development, including being the only one of the Stormtroopers to have a visible girlfriend.

Urusei Yatsura concerns the tempestuous relationship between two focal characters: Ataru Moroboshi who is possibly the most unfaithful, unlucky and lecherous idiot to have ever been born, and there's Lum, a tigerskin-bikini clad alien package of sex appeal, jealousy and electricity who's fallen for him. The series chronicles the misadventures of these two stubborn teenagers along with a veritable entourage of weird characters. Among these characters is the richest boy on the planet, a superhuman schoolgirl, a fire-breathing baby, a powerful priestess/school nurse, a cute and psychotic alien vixen with a split personality, a gender-bending martial artist, an alien biker chick, an ice queen of Neptune, a deranged monk, a giant ghost cat and hundreds of other lunatic personalities; aliens, humans and inhumans alike interract in endless hysteria in a town named Tomobiki.

In Urusei Yatsura: Beautiful Dreamer, Tomobiki High is in a frenzy to get ready for the school festival. Props need to be made, costumes designed, and maybe somewhere sleep to be had! Ataru, Lum, Shutaro, Shinobu, and the rest of Class 2-4 are determined to not be outdone this year, and they're rushing to make the final preparations for tomorrow's grand opening. 
 
Once they wake up the next morning, they continue their mad rush to get ready for tomorrow's grand opening. And then the next day... hey, isn't something strange going on? Silence lingers over the city, the buildings filled with nothing but dust and mold. Is this a dream? Or have the kids (and a few related adults) of Class 2-4 finally woken up? If they can spend each day having fun with each other, does it matter?

Strange things begin happening in Tomobiki Town... 
When a great cherry tree, "Tarozakura" is cut down while Lum & Co. are making a movie, Lum loses her horns-and her powers! Thus begins the strangest and most lyrical of the Urusei Yatsura movies...

The Urusei Yatsura story comes to a climax in this animated retelling of the final Manga story (although not the final movie). Lupa, yet another one of Lum's fiancés, arrives on the scene, and Lum and Ataru have to repeat their game of tag in order to prevent the Earth from being destroyed. 
All Ataru has to do to win is say "I love you" the three words he has steadfastly refused to say to Lum. Will he admit his true feelings and save the Earth? Or will his pride doom it to destruction?

Lum doesn't need much assistance going ballistic when everyone in Tomobiki gets an invitation to Ataru's wedding -- and she's not listed as the bride! It seems that some 11 years ago, Ataru played "Shadow Tag" with a young girl named Elle and won. Unfortunately, Elle was yet another Alien Princess; and on her planet, if a boy steps on a girl's shadow, they have to marry. 
When Elle's emissary comes to make arrangements, Lum redefines the term "the atmosphere was electric," but to no avail: a force-field now protects Ataru from her high voltage love-zaps. Lum's friend Benten suggests a pre-emptive wedding, and they proceed to abduct Ataru and all of the wedding guests, and the stage is set for the shotgun wedding of all time!

It seems that when Lum was born, a postal screwup resulted in a witchy friend of the family not getting an invitation to the celebration. The witch put a curse on Lum, that she would never be happy with her True Love. 
In the present, a new Amusement Park has been built in Tomobiki, and opening day finds the whole gang sampling its pleasures. At a magic show, however, Ataru gets turned into a large pink hippo-potamus, FOR REAL! 
When Lum attempts to track down the magician that transformed her Darling, things start to get very weird, very fast!

Lupica, another one of the legion of space princesses that all seem to have found out about Earth in some tour book, appears and abducts Ataru! 
But Lupica isn't after Ataru for his great looks or charming personality (because he doesn't have either). Lupica's goal is the greatest love potion in the galaxy, which she intends to use to induce her sweetheart to tie the knot. To get it, she needs the possessor of the greatest lust in the universe...

The adventures of Lum, Ataru, Ten, and all the gang from Tomobiki continue in an assortment of new &ndash; but no less weird &ndash; stories. 
Watch as Lum, Ataru, and Shinobu encounter a rabbit-clad youth, enter the Room of Destiny, and get a glimpse into their futures in "Inaba the Dreammaker," or see Ran's plans to use a sherbet cone-producing bird to open a sherbet shop one hot Tokyo summer go terribly awry in &ldquo;Raging Sherbet.&rdquo; Ataru has yet another bad experience with Lum's cooking in "I Howl at the Moon".
