''Dokkoida?!'' is a six-volume light novel series written by Taro Achi (with illustrations by Yu Yagami) that has been adapted into a three-volume manga (written and drawn by the same pair, released in English by CMX) and a twelve-episode anime series (released in English by Creator/{{Geneon}}) following the antics of the residents of Cosmos House both on and off the job.

Suzuo Sakurazaki has just come to the big city for college, but he needs a job. When Tanpopo, a green-haired little girl representing a toy company, offers him a belt that will transform him into the superhero Dokkoida, Suzuo mistakes the whole thing as an advertising gimmick. He realizes too late that it's for real, and toy companies can make weapons, too.

Tanpopo's company and a rival are, in fact, competing to market their super suits to the galactic police. Whichever one is proven more effective will gain a contract for mass production. To test them, the police have unleashed three powerful supervillains and promised a full pardon to whichever of them can successfully unmask our heroes. Everyone is provided Secret Identities, which if found out would render the entire test null and void. Despite this, budget constraints force everyone to be placed in the same apartment building.

And so Suzuo and his "new" little sister "Kosuzu" come to live at the Cosmos House apartment, befriending their (strangely familiar) neighbors while fighting for truth, justice, and winning the contract.


* ActionGirl: Asaka/Neuroloid Girl
* AllMenArePerverts: Parodied when all it takes is a soap opera episode to convince most of the women of Cosmos House that Suzuo is a sex fiend who wants to get it on with his little sister, and [[DirtyOldMan Marronflower's]] input does ''not'' help.
-->'''Tanpopo:''' It looks like [Suzuo] couldn't hurt a fly. I shouldn't judge him by his looks though, 'cause according to even the earliest edition of the Earth manual, [[InvokedTrope all men are basically depraved primates with cell phones]].
* AndYouThoughtItWasAGame: Suzuo
* ATwinkleInTheSky: Happens to Suzuo when he goes overboard welcoming Marilyn Ronmoe.
* BalefulPolymorph: Pierre
* TheBeard: In the manga, Suzuo's grandfather came to drag him back to the family business in the country since he's failing college, but will let him stay for love. Tampopo immediately [[OvernightAgeUp orders aging pills]] to pose as Suzuo's girlfriend. The other women (and Pierre) get more or less the same idea. [[spoiler:Grandpa doesn't buy it, but decides [[TrueCompanions friends]] are an acceptable excuse, too.]]

* LongTitle: The original Japanese title is ''Sumeba Miyako no Cosmos-sou Suttoko Taisen Dokkoider''
* LovesMyAlterEgo: Hyacinth, Edelweiss, and Neuroloid Girl aren't too crazy about Dokkoida, but each of them harbors feelings for Suzuo in their civilian identities. It's probably significant that this is a reversal of the most familiar expression of the trope.

* {{Meganekko}}: Kurika's [[RidiculouslyHumanRobot human form]].

* NoCelebritiesWereHarmed: Seriously, Marilyn Ronmoe?
* PantyShot: Edelweiss's initial attempt at a dramatic entrance is ruined by this.
* PaperFanOfDoom: Tanpopo's weapon of choice
* PaperThinDisguise: [[PettingZooPeople Petting Zoo Person]] Mogumokuru wears a cheap kabuki(?) mask over his snout to pass as human in the anime.

* PrecociousCrush: Ruri/Edelweiss towards Shizuo.
* PunchClockVillain / PunchClockHero: Somewhat literal, as everyone involved receive pay for living expenses.
