The Retro-Block
Name: The Retro-Block
Bios: When Metamorphia turned into a gas form and knocked out Sonic, she placed him within the walls of Robotnik’s Retro Block, a stone prison suspended in a beam that causes any force used within the walls of the Retro Block to be reversed back at the captive. Sonic managed to break out of the Retro Block by simply calming down, relaxing and thinking calm thoughts, which caused the block to explode with the reversed force.
