Sonic Prime (ソニック プライム, Sonikku Puraimu) is a CGI cartoon on Netflix based on the Sonic the Hedgehog series, and the newest animated Sonic series. It is produced by Canada's WildBrain, which is also the company that produced the 90's Sonic cartoons, Sonic the Hedgehog (Sonic SatAM), Adventures of Sonic the Hedgehog, and Sonic Underground (and which currently owns the rights to the series as a result of repeated acquisitions, mergers, etc.).
"When an explosive battle with Dr. Eggman shatters the universe, Sonic races through parallel dimensions to reconnect with his friends and save the world."
From Netflix's website.
The world of the Shatterverse was created when a jewel called the Paradox Prism was shattered, and various parallel worlds exist in the time-space called Shatterverse. Each of them has a different name.
The appearance in the usual world is of Green Hill Zone.
All actors shown also voice the alternative universes of these characters unless stated otherwise (it will be listed as AU).
