Bonkers is a simian-like mid-boss, wielding an enormous hammer which resembles King Dedede's.

In order to attack, Bonkers may charge at Kirby, jump in the air and swing his hammer, or throw Coconuts at Kirby to deal damage. These Coconuts may be engulfed then shot out to harm Bonkers. Once defeated, he lays on the ground for a bit, like all midbosses, when Kirby can inhale him and get Hammer ability. Since Bonkers is the only enemy with a hammer, he is the helper for the hammer ability. He appears in every game with the hammer ability.

In Kirby Super Star and Kirby Super Star Ultra, Bonkers is a common mid-boss that appears in Dyna Blade, The Great Cave Offensive, Milky Way Wishes, the Arena, Helper to Hero, and Meta Knightmare Ultra. He is also the helper for the hammer ability.

Kirby & The Amazing Mirror & Kirby: Squeak Squad

In both of these games, Bonkers appears as a Mid-Boss, looking and behaving essentially in the same way he did in Nightmare in Dream Land. He is often the only source of the Hammer ability in these games.

Team Kirby Clash Deluxe

Bonkers is encountered three times in this spin-off title. He's been made even larger, and his spinning moves made more elaborate to pose a challenge to four Kirby heroes working in unison.

Kirby Star Allies

Bonkers returns in this title, serving as a Mid-Boss as usual. Once defeated, he can be recruited as a Friend by tossing a heart at him before he explodes. As a Friend, Bonkers can use all the same moves as Hammer Kirby, and can also infuse his hammer with various elements.

Super Smash Bros. series

DS Kirby: Squeak Squad (NTSC) Kirby: Mouse Attack (PAL)
A large enemy who wields a giant hammer as a weapon. Bonkers battles you with several moves—his hammer attack and coconut throw could be considered his specialities. Kirby can inhale Bonkers to learn Hammer and Smash techniques.* Not many know this, but Hammer Kirby can also break walls and pound down stakes.

*= Kirby can't actually inhale Bonkers to get the Smash ability as it only gives him the Hammer ability. Kirby can only inhale Master Hand to get the previous ability.

Super Smash Bros. for Nintendo 3DS

Bonkers makes an appearance as an enemy in the 3DS-exclusive mode Smash Run.
