To use Amy’s All-Star Move, the player must have obtained an All-Star Item. When using it, Amy's vehicle gets a temporary increase in speed while her theme song "My Sweet Passion" from Sonic Adventure plays in the background. How her All-Star Move is performed depends on the game. In addition, Amy gains a special power unique to herself, which effect also depends on the game, for the duration of the move.
Sonic & Sega All-Stars Racing
In Sonic & Sega All-Stars Racing, Amy’s All-Star Move is referred to as the Piko Hammer. Upon activation, Amy will be surrounded by a heart effect. She will then pull out her Piko Piko Hammer and begin violently slamming the terrain around her, smashing any opponents that happen to get caught in her swings, hurting them and slowing them down.
Sonic & All-Stars Racing Transformed
In Sonic & All-Stars Racing Transformed, Amy’s All-Star Move is unnamed. When activated, the Pink Cabriolet is surrounded by a heart pattern, and Amy is given the ability to toss multiple Piko Piko Hammers at any opponents in front of her, slowing them down if they are to hit. Like all other All-Star Moves in Transformed, the Pink Cabriolet changes into plane mode if not already in said mode.
