Allies are anyone who helps Kirby on his adventures. Some allies have redeemed themselves and become friends with Kirby after their evil deeds, while others have been friends with him to begin with. Some allies are also playable in various games.
Elline is a magical paintbrush fairy who debuted in Kirby and the Rainbow Curse. She is friends with Claycia, and they both preside over the clay-based world of Seventopia. She encounters Kirby when Claycia goes mad and tries to kidnap her using Grab Hands, and they both set out to return Claycia to normal.
Villains are plot-centric characters who are the masterminds behind the events of the story of the games they appear in and fight against Kirby and company. Most villains don’t have any reasoning for their actions other than being evil, while others are given sometimes tragic backstories as to why they act this way.
Nightmare's operations are funded by his sales team including N.M.E. Sales Guy, his No.2 and right-hand man, who makes Nightmare Enterprises a hefty profit from selling Monsters to clients for their own needs.
Most of the time, enemies in the Kirby series refer to regular enemies. These are any common characters hostile towards Kirby and have less-than-significant role in the plot.
Daroach is the cunning leader of Squeak Squad, a gang of treasure hunting mice. His operational doctrine is that treasure would bring about endless power, and so he steals just about anything valuable. His greed came full circle when he bit off more than he could chew, and was possessed by Dark Nebula, becoming Dark Daroach. Daroach and the rest of Squeak Squad reconcile with Kirby after Dark Nebula's defeat, and would later cross paths with him again in Kirby Mass Attack.
The Kirby series is not known for its deep characters, but there are special ones just the same. These are characters who have strong and complicated connections with Kirby, or are neutral and defy classification into pure good or evil.
The slightly greedy, lazy, self-proclaimed king of Dream Land. He is Kirby’s arch-rival, leading some to believe that he is the main antagonist of the series. While he does have his fair share of evil deeds, King Dedede has gradually evolved as a character and has left behind his past with Kirby as his arch-nemesis, now having a (mostly) friendly rivalry with him. Most of the fights he had with Kirby were either misunderstandings or times when he was taken control of, however, some fights and actions were on his own accord, such as when he stole all of the food in Dream Land, or tried to humiliate Kirby in a tournament. Nevertheless, King Dedede has proved his worth when it came to facing off against evil beings alongside Kirby.
A solitary, stoic, and honorable character, Meta Knight is the mysterious rival of Kirby that everyone has come to know. With his masterful swordsmanship and unpredictable techniques, Meta Knight is a force to be reckoned with. While he may have had a somewhat rocky start with Kirby in the past, the two of them have gotten on much better terms and enjoy a friendly rivalry now and then, with Meta Knight making a worthy ally when things go awry. Under his mask, he bears a familiar face to the namesake hero himself, but one could wonder what their true connection really is.
Galactic Nova is a giant clockwork comet in Kirby Super Star and its remake, Kirby Super Star Ultra. It is summoned by the power of the Fountains of Dreams in the various planets near Planet Popstar, and has the ability to grant a wish. Galactic Nova will do whatever it takes to make that wish come true, whether it be a wish of good or evil will. Who it grants the wish to is not fixed, however, and Marx took advantage of that to wish for control over Planet Popstar.
