Sonic the Hedgehog 2 (ソニック・ザ・ヘッジホッグ2, Sonikku za hejjihoggu 2) (also simply Sonic 2) is the second entry in the Sonic series. It is a platforming game built as the sequel to the largely popular Sonic the Hedgehog, and has a sequel itself in the form of Sonic the Hedgehog 3. The story follows the titular Hedgehog and his new partner, Miles "Tails" Prower on their adventure to prevent the evil scientist Dr. Ivo Robotnik from stealing the Chaos Emeralds and powering his new weapon the Death Egg. Sonic and Tails, along the way, must fight through Robotnik's army, and free their friends.
