[[folder:Items associated with two or more versions:]]
%% * SugarWiki/AwesomeMusic: The OP and ED songs, which can be found over at AwesomeMusic/MegumiHayashibara.
* ClicheStorm: ''TV'' was a QuirkyWork featuring every well-known anime trope and cliche of the time, but [[PlayingWithATrope utterly dedicated to playing around with each and every single one]] and not taking itself very seriously. ''Dash'' on the other hand, played its cliches to the letter and was tossed into FanonDiscontinuity for it.
* FirstInstallmentWins: The original OVA series is generally held in high regard as opposed to the overly bizarre TV series and the melodramatic ''Dash'' OVA. Though the other two still have their fans as well.

[[folder:Items found in the OVA]]
* DesignatedVillain: Akiko is not so much a villain (questionable company policies aside) as she is both a MamaBear insistent on getting her beloved son Ryunosuke back and an aggrieved company president demanding the return of ''her'' property, the gynoid NK-1124. These provide reasonable motivation to pit her against the title character. Her antagonism is generally just played up for [[RuleOfFunny comedy]], and she largely loses the antagonist role after the second OAV.
* ToyShip: In the 6th OAV, grade-schoolers Ryunosuke and Yoshimi are implied to have a puppy-love crush on each other, with Ryunosuke's father teasing Ryunosuke about how happy he is to have Yoshimi over for Christmas.

[[folder:Items found in '''Nuku-Nuku Dash''':]]
* FanonDiscontinuity: ''Dash'' is generally disliked for making too many changes to the formula, among which are Ryunosuke being aged up from cute little boy to OrdinaryHighSchoolStudent and Nuku-Nuku becoming his hopeless crush instead of his sister and protector.
