Kirby has a smorgasbord of bosses that span its games, and while many recur across multiple games and generations in the franchise, more bosses are unique to their specific games, barring cameos here and there. Go here for the main character index.
A large, one-eyed, brass robot that tunnels under the ground. Kirby follows and fights it from behind as it works through the dirt with its saw-like appendages and mouth.
- Auto-Scrolling Level: The gimmick of the fight is that Kirby has to follow it as it tunnels, which depending on where it goes, can lead to Bottomless Pits, or Kirby getting crushed if the player isn't careful.
- Hidden Depths: A rare, non-positive example combined with a Pun according to Avalanche Heavy Mole is a powerful Underworld figure who's known for underhanded tactics.
- Flunky Boss: Fires off projectiles called Dygclops as an attack. Brown ones give the hammer ability, while red ones give Sleep, which, considering the nature of the fight, can be a death sentence.
- Overheating: A big machine like Heavy Mole would naturally heat up fairly quick and have to vent itself out at some point. Naturally, these points are where it slows down to cool and gives Kirby an easy chance of catching up and attacking.
A large wild boar and boss of Big Forest, Nruff runs across a series of dilapidated bridges hung between a pair of hollowed out trees with his minions, the smaller Nellys.
- Composite Character / In Name Only: Nruff became more like Nelly after their first major appearance, gaining the juvenile back markings, losing the tusks, but keeping the eyes and name.
- Degraded Boss: The Boss of Big Forest in Kirbys Dreamland 2, Nruff became a normal enemy afterwards, to the point that in Kirby Star Allies hes a mount for Waddle Dees.
- Flunky Boss: The Nellys follow Nruff around to serve as ammo for Kirby.
- Full-Boar Action: One of the earliest examples in video games at that.
- Turns Red: After getting down to half health, Nruff begins mixing up his charging, and actively jumps from bridge to bridge mid-charge to confuse the player.
