North Pole

"We're going to the North Pole! That means Metal has finally found the point of destruction. You should get ready now Sara!"

- Dr. Robotnik wanting to marry Sara.

The North Pole (北極 Hokkyoku) is the location where Hyper Metal Sonic heads to destroy Planet Freedom.

Sonic VS. Metal Sonic!!
Metal, in the sky, is ordered to destroy Planet Freedom, so he does this by melting glaciers and causing magma to erupt. When he already caused the magma problem, he scans Sonic, running towards him after hearing reports of him at this place. Sonic looks up, noting that he is too late for preventing damage. Surprisingly, Metal rises underground, under Sonic's feet. They drift apart and face each other. They both come to an agreement that the last one standing will deserve the title of the name Sonic.
