Skull Squadron was the squadron commanded by Amy Rose ever since the beginning of the New Clone Wars.
The squadron first flew in the opening battle of the New Clone Wars. At that time there were only twelve members. The squadron was so named due to their choice of the Z-95 Headhunter( or "Skull") as a primary starfighter. After Amy tested the Viper Mark II, they became a Viper Squadron and gained eight new members.
