* Meta Knight has been in absolute ''command'' of the fandom's attention from his debut, not only as both Dedede's DragonWithAnAgenda and TheCaptain of the Meta-Knights [[spoiler: but also as the only other known member of Kirby's species for over a dozen years until ''Super Star Ultra'' introduced Galacta Knight]]. Following his debut, he immediately became an AscendedExtra and the BigBad of one of ''Super Star'''s mini-games, and then a series of major plot roles and occasionally playable appearances (starting with ''Nightmare in Dreamland''), both in his home series and in ''Super Smash Bros.'' He's absent from ''Triple Deluxe'', for some reason ([[spoiler: though Dark Meta Knight returns as the final boss of Dededetour]]), but finally returns in full glory for ''Planet Robobot''.
* Galacta Knight from ''VideoGame/KirbySuperStar Ultra'', who, despite merely being a BonusBoss for the VideoGameRemake, gained huge popularity with the fandom, particularly in the area of [[WildMassGuessing speculation]] regarding his relation to Meta Knight.
** Apparently, the higher-ups were savvy enough to pick up on this, as [[spoiler:Galacta Knight returns as a BonusBoss in The True Arena of ''VideoGame/KirbysReturnToDreamLand''.]]
* Rick, Kine, and Coo, the animal friends from ''VideoGame/KirbysDreamLand2'', are beloved by the fanbase, enough that in spite of only being part of the gameplay in their debut game and [[VideoGame/KirbysDreamLand3 its sequel]], they make cameos throughout the series. They even got to appear in [[Anime/KirbyOfTheStars the anime]] in spite of the fact that they were not created by Sakurai.
* The one-shot characters from ''[[VideoGame/Kirby64TheCrystalShards Kirby 64]]'', such as Adeleine, Ribbon, and 0[[superscript:2]] have a TON of fanart for them. 0[[superscript:2]] may mainly have been popular due to being suprisingly symbolic for a ''Kirby'' game (he spits out blood) and due to his [[AwesomeMusic/{{Kirby}} awesome battle music]]. 0[[superscript:2]] even got a remix of his theme music in ''Brawl''. Ribbon's popularity is probably due to her [[ImpliedLoveInterest implied relationship]] with Kirby. Adeleine became a recurring character in the webcomic ''Webcomic/BrawlInTheFamily''.
* Bandana Dee, [[AscendedExtra who went from]] one-shot opponent in a ''Super Star'' minigame, to the confirmed identity of the Waddle Dee boss in the remake (with speaking parts!), to a playable character in ''VideoGame/KirbysReturnToDreamLand'', is gaining in popularity lately. Some {{Fanon}} even holds that he's the same Waddle Dee who partnered with Kirby in ''Kirby 64,'' just without his IconicItem.
** [[LampshadeHanging Hell, just take a look at his pause screen description in]] ''[[LampshadeHanging Return to Dream Land]]'' [[LampshadeHanging and the first words you'll see are "Hey, it's everyone's idol!"]]
** In the time between ''Return to Dream Land'' and ''Plnet Robobot'' he has made more appearances than both Meta Knight and King Dedede.
** He's even become a very popular request for ''Super Smash Bros.'', and given how important he is nowadays, it's easy to see why some people thought he might have been a candidate to be put in.
* Many of the enemies may also qualify, such as Waddle Doo and Knuckle Joe (who might both owe this to [[Anime/KirbyRightBackAtYa the anime]]).
** Sword Knight definitely qualifies. Despite not appearing as often as Blade Knight, he has a large fanbase.
* ''Kirby 64'' is a Darkhorse game for the series. Aside from starring the aforementioned characters, it's a great aversion of PolygonCeiling, opting for a 2.5D presentation that keeps the gameplay unchanged, while providing some of the best animations and background art for the console. It possesses a fair amount of challenge while not being unfairly hard, and the popular mechanic of combining powers hasn't been seen since. Nowadays any game featuring character cameos or remixed music from the game is typically met with enthusiasm by fans.
* A lot of fans have noticed that certain characters from [[Anime/KirbyRightBackAtYa the anime]] have made cameos in ''VideoGame/KirbyMassAttack'', and fans of said anime naturally squeal with joy upon seeing them again. These characters include Escargoon, the NME salesman, Chef Shiitake, and Max Flexer.
