Amy using the Hammer Attack in Sonic the hedgehog (2006)
A wack with the Piko Piko Hammer.
The Hammer Attack (ハンマー攻撃 Hanmā Kōgeki?) is Amy Rose's signature attack. It first appeared in Sonic Adventure and has since then been established as Amy's primary offensive maneuver in the Sonic the Hedgehog series. It is a technique where the user attacks with the Piko Piko Hammer.
Unlike most other characters in the Sonic series, Amy often lacks the ability to perform the Spin Attack and the different versions of it. To compensate for this, Amy instead uses her skills with her personal weapon, the Piko Piko Hammer, to attack her enemies. In the Sonic game series, the basic Hammer Attack is where Amy calls out her Piko Piko Hammer and whacks the opponent in front of her while sometimes leaving a trail of pink hearts. This is usually done in gameplay by tapping the Action button.
In Sonic Advance 3, if any of the lead characters (Sonic, Knuckles, Tails or Cream) have Amy as his/her partner, they can perform the Hammer Attack as well, with their own version of the Piko Piko Hammer.
Over time, Amy has developed several uses of the Hammer Attack to give her more offensive options, mimic some uses of the Spin Attack and to make up for her lack of raw strength.
