The mysterious vortex brought Bonkers to the new world too! They arrived before Kirby and quickly joined the ranks of the fearsome Beast Pack. They really like their new look, and they're getting along with all of their new coworkers...especially the Mookies!
— Capsule Description • Kirby and the Forgotten Land

Bonkers (referred to as Wild Bonkers in Kirby and the Forgotten Land) is a gorilla-like mid-boss in the Kirby series. He has armor and a giant hammer. He also sometimes tosses explosive coconuts that Kirby can inhale and use as projectiles. Certain coconuts that he throws in Kirby games including, and after, Kirby & The Amazing Mirror are larger than others, and in games with health bars, both of them do more damage. When Bonkers is swallowed, Kirby gets the potent Hammer ability. In Kirby Super Star and Kirby Super Star Ultra, he appears as the Helper for the Hammer ability. He reappears in Kirby's Return to Dream Land, Kirby's Dream Collection Special Edition, Kirby: Triple Deluxe, Kirby: Planet Robobot, Team Kirby Clash Deluxe, and Kirby Star Allies, once again serving as the Helper for the Hammer ability in the latter game.

Bonkers appears in the New Challenge Stages in Kirby's Dream Collection Special Edition as well. He appears in the Fighter Combat Chamber and the Smash Combat Chamber EX.

Physical Appearance

Bonkers appears to be a gorilla-like creature who wields a large hammer, and has no visible eyes. He appears to wear dark blue pants with torn legs and a belt, and a "jacket" with slits in it for his arms. The muscles on his arms are concentrated to the area around his supinator, in a similar fashion to Popeye. He also has purple sideburns and a pompadour haircut. In Kirby: Planet Robobot, Bonkers is mechanically modified, as his ears and lower jaw are covered with metal.


Kirby's Adventure and Kirby: Nightmare in Dream Land

Bonkers appears in these games as a mid-boss, as the main source of the Hammer ability. He is also fought in the Yogurt Yard Arena.

Bonkers' attacks include charging forward and then pounding the ground with his hammer, jumping up and down, leaping forward, and throwing explosive coconuts which can be inhaled and spat back at him. Occasionally, Bonkers will pound his hammer multiple times. If Kirby is in the air while Bonkers is charging forward, Bonkers will jump upwards before pounding his hammer.

Kirby Super Star and Kirby Super Star Ultra

Bonkers returns in these games as a mid-boss, where he uses the same attacks as in his initial appearance, in addition to a new attack in which he sends out multiple explosive coconuts instead of one. He is also the Helper for the Hammer ability. As an ally, he wears purple armor, which has since become his main coloration in the series. As a Helper, he has access to most of Hammer Kirby's attacks except for the Hammer Throw, probably because Helpers cannot lose their abilities. Along with Bugzzy, Bonkers is the largest Helper, standing twice as tall as the other Helpers. In Kirby Super Star Ultra, Bonkers appears in Helper to Hero, wearing red armor.

Kirby & The Amazing Mirror

Bonkers reappears as a mid-boss. While he uses the same attacks, he will now occasionally throw a larger explosive coconut which does more damage.

Kirby's Return to Dream Land

Bonkers returns as a sub-boss, using the same attacks as before, in addition to new attacks such as the Hammer Spin and moving forward to unleash a Hammer Flip. In Extra Mode, he wears black armor and red pants, sports a red pompadour and his hammer has a metallic tone. Here, he is referred to as Bonkers EX. His attacks are faster and more aggressive, and he has a new attack in which he does a Hammer Spin in the air, hovers in place and sends out explosive coconuts everywhere.

Kirby: Triple Deluxe

Bonkers reappears as a mid-boss with new techniques, which includes doing a Hammer Twirl while jumping around which leaves flames on the ground with every bounce, and using Hammer Spin to hover in and out of the background. He will use the latter more at low health. As Bonkers DX, the flames from his Hammer Flip and Hammer Twirl are a darker shade of red.

Bonkers has been mechanically modified, as his ears and lower jaw are covered with metal. Aside from that, his attacks have not changed. As Bonkers 2.0, his explosive coconuts are green in color.

While Bonkers himself does not appear, a robotic version of him known as Robo Bonkers appears as the boss of the battle mode of the same name.

Kirby Star Allies

Bonkers appears as a mid-boss and as the friend for the Hammer ability. He now wields his hammer in his right hand. As a mid-boss, he uses most of his attacks from previous games, with the exception of the hovering Hammer Spin. A stronger version of him appears in the later stages, with black armor, a black pompadour, red pants, and white skin. The star on his hammer is also black. This version's Hammer Spin lasts longer, and brings back his Hammer Twirl move, with pink flames being left on the ground with every bounce. As a Friend, he can now use Hammer Throw an infinite number of times. Bonkers also stars in Guest Star ???? Star Allies Go!, changing the name to Guest Star Bonkers Banana Mania, which emphasizes Bonkers's previously absent love of bananas.

Bonkers appears in the game's boss rush mode, The Ultimate Choice, as a part of Mid-Boss All-Stars #1. He appears in six levels of difficulty (Sweet Breeze, Spicy Adventure, Sizzling Threat, Fiery Showdown, Infernal Crisis and Soul Melter).

During the Soul Melter EX, Twin Bonkers is instead fought.

Kirby and the Forgotten Land

Bonkers reappears in Kirby and the Forgotten Land under the name of Wild Bonkers. He joins up with the Beast Pack and has a more ragged appearance. He primarily uses the same attacks from Kirby Star Allies, although these attacks are now accommodated for the 3D environment while throwing durians rather than his coconuts. During his second phase, he can sometimes spin to throw large barrages of them.

In Kirby: Right Back at Ya!

Me want to train with Kirby.
— Bonkers • Kirby: Right Back at Ya!

Bonkers makes an appearance in Kirby: Right Back at Ya!, appearing in the 79th episode Goin' Bonkers.

Bonkers in his monster form.

In the anime, Bonkers lived in a jungle until a circus crew captured and trained him for the circus. While Bonkers was held in a cage against his will, the ringmaster decided to watch his favorite show, which was the Kirby: Right Back at Ya! show. This is how Bonkers got inspired to meet Kirby in person, so, without letting the circus find out, he quietly escaped and wandered off to Dream Land in search of his favorite hero. When he finally got to Dream Land, the Cappies at first thought he came to battle Kirby, but soon everyone learned that Bonkers really wanted to train with Kirby. Knowing this, King Dedede had plans for Bonkers, so first he asked Bonkers to impress Kirby with his hammer skills, and tried to smash Kirby with a boulder, but Bonkers smashed the boulder with his hammer to make sure his favorite superhero wasn't hurt at all. Dedede finally resorts to taking him all the way to his castle and getting Nightmare Enterprises to turn Bonkers into a monster. He was later returned to normal thanks to Hammer Kirby, however, and he left, hoping to continue his training.

In the Japanese version of the anime, Bonkers says he's a Star Warrior in training, meaning that he is not from Planet Popstar. This might be true, as he unnaturally has been wearing his armor before he is captured.

Physical Appearance

Normal Form

Bonkers' appearance in the anime is similar to his in-game counterpart, appearing as a large, gorilla-like creature who wields a large hammer, and has no visible eyes. He appears to wear dark blue pants with torn legs and a belt, and purple armor with slits in it for his arms. The muscles on his arms are concentrated to the area around his supinator. Unlike the games, however, he has brown fur on his arms. On his back is a scabbard for his hammer, which has a red uppercase B on both ends of the head.

Monster Form

In his second form, Bonkers is similar to his original form, only more muscular, has sharper teeth and has visible dark red eyes, thicker fur, and razor-sharp claws.

Powers and Abilities

Normal Form

In his normal form, Bonkers can throw small rocks and can swim with ease. He displays great physical strength and can jump at incredible heights. For weaponry, Bonkers wields a hammer, which he can either store on his back and hit his enemies with it by bowing down and having the hammer drop down on them or wield the hammer for combat. The hammer itself is strong enough to break a boulder in just one hit.

Monster Form

In his monster form, Bonkers has the same abilities that he has previously and his hammer for combat, but now gets an increase in strength.

In the Super Smash Bros. series

Bonkers appears as a trophy and sticker in Super Smash Bros. Brawl. The sticker uses his artwork from Kirby: Squeak Squad and increases Weapon Attack by 16 for all Kirby representatives.

Bonkers appears as an enemy in Super Smash Bros. for Nintendo 3DS’s Smash Run mode. Arguably the strongest Kirby enemy in the game, he can take many hits, deals great amounts of damage, and does not flinch when assaulted. He primarily attacks with Hammer Nail (which can trap the player in the ground), Hammer Swing, and Hammer Flip (which he winds up for an upward blow like Kirby's version instead of a downward smash). Bonkers drops huge Stat Boosts when defeated. In addition to appearing as an enemy in this game, Bonkers appears as a trophy.

Spirit battle

Bonkers appears as a Primary, Ace-class Attack spirit in Super Smash Bros. Ultimate. His spirit sports no effect when equipped.
