'''Basic Trope''': A one-shot villain created for a {{Filler}} arc.
* '''Straight''': The MagicalGirl series ''[[PlayingWithFire Blazing]] [[LuckyCharmsTitle He]]♥[[LuckyCharmsTitle rt]] [[StrawberryShorthand Ichigo]]'' enters a {{Filler}} arc that wasn't in [[ExpandedUniverse the original series]]. The arc's BigBad is BloodKnight Rubia, and after her [[KilledOffForReal decisive defeat]], she's never brought up again.
* '''Exaggerated''': Rubia and her followers, the [[FourIsDeath four]] Crimson Heralds [[PsychoForHire Rosso]], [[CombatSadomasochist Carmine]], [[SpiritedCompetitor Scarlett]] and [[CreepyChild Rosy]] square off with Ichigo for a sprawling filler arc that takes up almost the entire season. Despite how long and difficult the battle was, they're lucky to get even a vague reference afterwards.
* '''Downplayed''': Rubia was nothing more then a simple mook in the origanal series, the adpaptation gives her motives and personality.
* '''Justified''': Rubia attacked Ichigo expecting to earn fame and glory, stomping on her BerserkButton to goad her into battle; Ichigo deliberately undermines her wishes by [[KillItWithFire blowing]] [[CurbStompBattle her away]] and refusing to acknowledge her as being on the same level as her other adversaries.
* '''Inverted''':
** The adaptation removed Rubia's arc [[CompressedAdaptation to save time]].
** During a filler arc, Ichigo is joined by Ringo, a novice magical girl who [[TheKnightsWhoSaySquee wants to be just like Ichigo.]] After Ringo's HeroicSacrifice at the end of the arc, she's never mentioned again.
* '''Subverted''': Scarlett turns out to have HiddenDepths, pulling a HeelFaceTurn when Ichigo helps him with DefusingTheTykebomb that Rubia turned his baby sister Rosy into. In the process, he also grows into a potential LoveInterest for Ichigo.
* '''Double Subverted''': Once Rubia is defeated once and for all, however, Scarlett and Rosy are PutOnABus for their happy ending off-screen while Ichigo gets back to the main plot, never even sparing a thought for her TemporaryLoveInterest.
* '''Parodied''': Rubia freely admits she has no real reason to challenge Ichigo other than [[ItAmusedMe amusing herself]]. Ichigo also takes a cavalier approach to the whole arc, figuring that it's better than being bored waiting for some ''real'' challenge.
* '''Zig Zagged''': Rubia appears in another adaptation of the original work, but her story is exactly the same, right down to being never referenced again.
* '''Averted''':
** {{Filler}} for the series focuses solely on CharacterDevelopment.
** Rubia becomes a CanonImmigrant or gets a ContinuityNod.
* '''Enforced''': The ''Blazing He♥rt Ichigo'' {{Anime}} OvertookTheManga (or threatens to), so the writers created Rubia as a stopgap measure.
* '''Lampshaded''': [[BreakingTheFourthWall Ichigo points out that Rubia wasn't in the original. Rubia admits to it and says she won't be mentioned again after this.]]
* '''Invoked''': Ichigo advertises for {{Filler}} villains while waiting for the Manga to catch up.
* '''Exploited''': Ichigo strives to have villains that won't be seen again because she doesn't have to worry about them anymore.
* '''Defied''': Rubia knows she won't be seen again, which drives her to somehow [[NothingIsTheSameANymore force a change to the status quo]].
* '''Discussed''': "You're just a one-shot villain made up this story and won't be seen again!" "Yeah, I know. BUT I'LL STILL DO MY BEST!"
* '''Conversed''': "Why did they ever bother with Rubia? They never mentioned her again". "That's cause the anime was ahead of the manga and the writers had to make something up".
* '''Deconstructed''': After Rubia's defeat, Ichigo promptly forgets not only about Rubia but also about Rubia's tactics, weapons, and weaknesses. This causes a problem when a later villain uses Rubia's exact strategies. Ichigo [[HeroicBSOD breaks down]] when she realizes she could have prevented a lot of devastation if she hadn't forgotten.
* '''Reconstructed''': The audience learns later that Rubia and the Crimson Heralds were written into reality to fill the void left behind by other (read: canon) villains. After their defeats, they are [[RetGone completely erased from reality]].
* '''Played For Laughs''': Ichigo gets a BreatherEpisode where UnknownRival Sherbert comes out of nowhere to challenge her to a [[CookingDuel volleyball]] contest. Using magical fire and bubbles to make the 'ball'.
