Sonic X Union Academy

On a distant planet, Sonic, a young anthropomorphic blue hedgehog who can run at supersonic speed, is unexpectedly attacked by an echidna tribe. His guardian, an anthropomorphic owl named Longclaw, gives him a bag of golden rings that open portals to distant locations. She uses one to send him to Earth while she stays behind to hold off the echidnas, leaving Sonic alone.

Ten years later, a teenage Sonic enjoys a secret life in a cavern under the rural town of Green Hills, Montana where the Union Academy is, but longs to make friends. He idolizes the local sheriff Tom Wachowski, his wife Maddie and Union Students unaware that the pair are planning to relocate to San Francisco as Tom plans to accept a job at the SFPD.

One night, Sonic grows upset over his loneliness while playing baseball alone and, while running at unusually high speeds, accidentally triggers an electromagnetic pulse that causes a massive power outage across the Pacific Northwest. The U.S. Department of Defense reluctantly enlists the services of eccentric roboticist and scientific genius Dr. Robotnik to determine the cause of the outage. Realizing his cover has been blown, Sonic reluctantly plans to leave Earth for a different planet only containing mushrooms and fungi.

As Sonic prepares to leave, Tom discovers him in his shed and tranquilizes him. Upon reading the writing on Tom's shirt, Sonic accidentally opens a portal to San Francisco and drop his bag of rings through the portal to the Transamerica Pyramid's roof before passing out. After Sonic recovers, Tom hesitantly agrees to help him and the two flee when confronted by Robotnik.

How will the two survived this?
