From Sonic Retro
Circular Attack is a move available to all four Power type characters in the Sonic Heroes teams: Knuckles the Echidna, E-123 Omega, Big the Cat, and Vector the Crocodile. After firing both teammates with in Fire Combination, the character breaks out a final radius-of-effect move which is potentially the game's strongest bar Team Blast.
The strength and nature of a Circular Attack depends on how many Power Cores the user has collected.
