ZERO is a minor character featured in the anime series Sonic X.
ZERO was created as one of Dr. Eggman's E-100 Series. It captured Amy and Lily in Station Square and took her to the doctor in the Egg Carrier much like in Sonic Adventure. ZERO somehow survived the crash of the Egg Carrier and assisted Decoe and Bocoe in battling Amy and Lily when they arrived. However, it was knocked out by Amy.
