Invisibility

Invisibility is a special move used by Amy Rose in Sonic the Hedgehog (2006). By concentrating her energy, Amy can turn herself completely invisible.

Description
To perform this move, hold down the Square/X button (depending on method of gameplay) for a short time. Amy will then concentrate a pink type of energy, which starts to envelope her. Once the energy has been focuced, several transparent rings will move up and down Amy's body, which will then turn her completely invisible for 15 seconds. While in this state Amy cannot be found by the enemy. However, she is not 100% invisible, as her Piko Piko Hammer and shadow can still be seen.

It is unknown why Amy was given this power in Sonic the Hedgehog (2006) but it may be because, Amy always had this power but simply never had a chance to use it.

Trivia

 * If Amy is walking on the ground when the Invisibilty wears off, she will stop and look over herself.
