The Extra Life is a character that appears in the Sonic the Comic series published by Fleetway Editions. He is an evil clone of Sonic the Hedgehog created by Dr. Ovi Kintobor before he became Dr. Robotnik. The Extra Life looks identical to Sonic the Hedgehog, except he has slit-shaped pupils, messier fur on his ears, and sharp fangs for teeth. The Extra Life was created by Dr. Ovi Kintobor, before the accident that turned him into the ruthless Dr. Robotnik, to help his friend Sonic the Hedgehog
