Sonic the Hedgehog 2 Guide

Sonic the Hedgehog

Sonic keeps the Spin Jump and roll and gains a chargeable Spin Dash. In the original game, collecting seven Emeralds allows him to become Super Sonic when the ring requirement is met.

Sonic and Tails in the original Aquatic Ruin Zone.

Miles 'Tails' Prower

Tails can accompany Sonic, be controlled by a second player or be selected alone. In the 1992 release, players cannot manually activate his flight; the computer uses it to return him to Sonic.

Tails races in the lower half of the original competition screen.

Dr. Robotnik

Robotnik imprisons animals and pursues the Chaos Emeralds to power his space station. His changing machines supply the Zone bosses and the final Death Egg Robot.

Mecha Sonic

The metallic Sonic-shaped opponent waits in Death Egg Zone before the larger final robot. Its rolling and spiked attack patterns make uncontrolled jumping dangerous.
