The Piko Piko Hammer (ピコピコハンマー PikoPiko Hanmā?), also called the Piko Hammer or Love Hammer, is Amy Rose's signature weapon. It is a large yellow and red hammer that Amy uses as a melee weapon in combat, to execute better movements and perform special techniques.

Concept and creation

The Piko Piko Hammer was originally based on a popular Japanese children's toy of the same name. The phrase "piko-piko" is an onomatopoeia for the chirping sound that these hammers make when struck (which can also be heard in several games when Amy attacks).

The Piko Piko Hammer made its first appearance in Sonic the Fighters, in which Amy used it as a part of her combat moves. She was given the hammer as a weapon in order to strengthen her tomboyish nature (note that this is also the reason why she is a playable character in the game). As a result, she does not punch.

The Piko Piko Hammer's original design.

The Piko Piko Hammer mostly resembles a double-faced sledgehammer or mallet. Originally, it had a red head with flexible yellow faces and a pink handle. By the time of Sonic Adventure, the Piko Piko Hammer was redesigned with a larger, cylinder-shaped red head with raised rectangular sections on the middle, thick yellow face disks, and a brown handle. While this design has occasionally reappeared and served as the Piko Piko Hammer's fundamental look since then, it has more frequently been depicted with flatter face disks and without the rectangular sections on the head. In some cases, the colors of the Piko Piko Hammer's head has even been inversed.

The size of the Piko Piko Hammer's head often differs. Usually, it is slightly bigger than Amy's head. In other cases however, it is much larger, reaching sizes greater than the Pink Cabriolet.

Features and traits

Despite its colorful and innocent appearance, the Piko Piko Hammer is a powerful melee weapon, capable of dealing incredible damage with seemingly little effort. It can effortlessly smash whole robots with a single swing, yet is graceful enough to be used for high-speed techniques. It can likewise sent foes flying with a single hit or crush them with devastating force. At as a testament to its might, even fearless individuals like Sonic and Knuckles dread getting a beating from the Piko Piko Hammer.

Mixed with Amy's abilities, the Piko Piko Hammer can be used for many applications beside combat. When swung around fast enough and with the right amount of force, the Piko Piko Hammer can function as a propeller for flight, launch powerful shockwaves that can steer up miniature tornados or unleash massive releases of energy, and provide boosts for different acrobatic maneuvers.

When not using it, Amy keeps the Piko Piko Hammer in a hiding spot that remains unknown to this day,[1] but she can pull it out of nowhere on a moment's notice.


Throughout the Sonic the Hedgehog series, Piko Piko Hammers other than Amy's regular hammer have appeared. These Piko Piko Hammers differs between each in appearance, and can possess traits unique to them.

In Sonic Adventure and Sonic Adventure DX: Director's Cut, Amy can obtain an Level Up Item called the Long Hammer, which is an upgraded version of her regular Piko Piko Hammer. This Piko Piko Hammer increases the radius of Amy's attacks.

In Sonic Advance 3, when selecting Amy as a playable character, her partner will obtain a uniquely stylized Piko Piko Hammer, allowing him or her to use the Hammer Attack.

In some games, Amy is shown to possess a Piko Piko Hammer much larger than her regular one. In Sonic Advance 3, Amy can use this Piko Piko Hammer as a part of her Big Hammer Attack when having Knuckles the Echidna as her leader or sidekick, allowing her to attack with much more power. This Piko Piko Hammer reappeared during the credits of Sonic's story in Sonic Rush when Amy was chasing after Sonic.

The Piko Piko Hammer appears in the Archie Comics' Sonic the Hedgehog and its subsequent spin-offs as Amy Rose's signature weapon. It features the same design it had in Sonic Adventure. In this media, the Piko Piko Hammer was created as a by-product of Amy's usage of the Ring of Acorns. After absorbing the Ring of Acorns's power to make herself older, Amy obtained limited wish-granting abilities that allows her to wish forth the Piko Piko Hammer whenever she wants.

Following the timeline reboot caused by the Super Genesis Wave, the Piko Piko Hammer is now virtually identical to its game counterpart.

Sonic X

The Piko Piko Hammer appeared as Amy Rose's signature weapon in the anime Sonic X and the comic series of the same name published by Archie Comics. It features the same design it had in Sonic Adventure.

Like in the games, the Piko Piko Hammer is Amy's personal weapon that she is able to inexplicably pull out of thin air. Additionally, it appears Amy has an inexhaustible supply of Piko Piko Hammers, having demonstrated the ability to conjure up another Piko Piko Hammer out of nowhere by just by waving her hand.

In the Sonic Boom franchise, the Piko Piko Hammer is referred to as either the piko hammer or Amy's Hammer, and is Amy Rose's primary weapon. In this media, it bears a resemblance to its Sonic Adventure design, but with thicker faces, pink disks, a leather strap and a pink color scheme. Amy wields it with noticeably more proficiency than her game counterpart, combining her agility and gracefulness with its heavy-hit strikes for maximum efficiency. She has also used it as a hook and projectile.
