Bettle

"A flash of light reflects off its horn as the king of bugs soars through the sky! After charging your enemies to grab them with your horn, you can slam them into the ground!"

- Kirby: Triple Deluxe pause caption Beetle is an ability that gives Kirby the horn and wings of a Japanese rhinoceros beetle. It is unique in the fact that after grabbing enemies, Kirby can still walk and jump, albeit more slowly and less high, respectively. Kirby also only faces one direction when carrying enemies, forcing him to walk backwards when moving in the opposite direction, although this has no effect on anything except the direction enemies are thrown. Another notable thing about this ability, is that it has the ability to pound down stakes with Hardhead Slam. The ability can only be obtained from the the enemy Beetley, and the mid-boss Hornhead. It was introduced in Kirby: Triple Deluxe along with Bell, Circus, Archer, and Hypernova. It later returned in Kirby Battle Royale and Kirby Star Allies after being absent from Kirby: Planet Robobot.

Kirby: Triple Deluxe
"Kirby gets a cool horn with the new Beetle copy ability. Try using Horn Upper to scoop up enemies or unleash a quick attack with Rocket Horn. The horn can also catch multiple enemies at once and hammer stakes. Inhale enemies like Beetley and Hornhead to try it out!"

- Satoshi Ishida, Miiverse post on 05/20/2014 9:20 AM Beetle debuts in this game, and can be obtained from Beetley or the Mid-Boss Hornhead. It is a versatile ability, granting Kirby the ability to fly with wings, cut Ropes, pound Stakes, and grab enemies with the beetle horn. This makes it handy for solving many puzzles in the game.

Kirby Fighters Deluxe
Beetle appears as one of the selectable Copy Abilities in this title, though access to it requires that the player has save data for Kirby: Triple Deluxe on his/her Nintendo 3DS system. It functions identically to the way it did in the previous game.

Beetle Kirby's Rare Outfit is Hydra, the legendary machine from Kirby Air Ride.

Kirby Battle Royale
"Look at that horn on you! The Beetle ability sure looks impressive. Use Rocket Horn to grab foes and Dive to drive them into the ground."

- Knuckle Joe's comment from Kirby Battle Royale Beetle appears as one of the selectable copy abilities in this spin-off title. It is a starter ability which does not need to be unlocked. The main power of Beetle is its ability to grab other fighters using the Rocket Horn technique, then slamming them into the ground to deal massive damage. This is a good way to intercept other players, and force them to drop any items they may be carrying, as well as moving them forcefully toward or away from certain spots.

Three alternate pieces of Headgear are available for the Beetle ability. These include the "Hornhead Helmet", the "Woodpecker Hat", and the "Hydra Helmet".

Kirby Star Allies
"A flash of light reflects off its horn as the king of bugs returns! You can pound stakes with Hardhead Slam and use ↑ to gather your friends on your head and fling them into the air!"

- Kirby Star Allies pause caption Beetle returns in this title, once again provided by (and represented by) Beetley. It retains all of its essential moves from Kirby: Triple Deluxe, and gains access to the Friend Throw ability, which it shares with Fighter and Suplex.

Trivia

 * Some of Beetle's moves are notably similar to the Suplex and Throw abilities. Also, Suplex is obtained from the mid-boss Bugzzy, who is similar in appearance to Hornhead.
 * This is the fourth ability to give Kirby a unique flying animation. The others are Jet, Wing, and Cupid.
 * The design of the Beetle hat is based on the Japanese Rhinoceros Beetle. It also takes a couple details from feudal samurai armor.
 * Friend Throw's Japanese name, ブンナゲフレンズ, derives from ぶんなげ, the Japanese name of Beetle's 'Quick Throw' attack. This reference is kept in the Chinese version of Kirby Star Allies:
 * Beetle's 'Quick Throw': 力投 (Power Throw)
 * Friend Throw: 力投盟友 (Power Throw Friend)
