Multiverse Unity: Sonic and the Tomb Raider

Sonic and the Tomb Raider is an American English animated miniseries airing on Netflix, and a crossover between the video game franchises Sonic the Hedgehog by Sega and Tomb Raider by Crystal Dynamics.

Premise
Having moved his way from San Francisco, USA to London, England, Sonic the Hedgehog earns a new human friend with Lara Croft, the teenage hereditary of the Croft Family who aspires to be a notorious archaeologist and treasure hunter like her late father Richard Croft before her. The two undergo a series of adventures around the world while discovering mystical relics and standing against Jacqueline Natla and Dr. Robotnik; both seeking to capture Sonic for his superhuman speed powers, overthrow Lara and take over the Croft Family's fortunes. Among other foes and threats, Sonic and Lara also have to deal with the manipulations of Larson Stone, who is masquerading as an associate for both Robotnik and Natla for his own malicious favors and purposes.

Characters
The characters and environment of the miniseries use remastered animation tone similar to the 2010-2012 animated series The Avengers: Earth's Mightiest Heroes!.

Main Characters

 * Sonic the Hedgehog (voiced by Robbie Daymond) - One of the two core protagonists. A 15-year-old anthropomorphic blue hedgehog from Mobius with superhuman speed powers who is secretly living a life on Earth, and is spending his days with Lara in the Croft Manor after relocating from San Francisco, USA, to London, England. Having lived a life on Earth since his childhood, Sonic has been travelling around numerous countries around the world (including Japan, Brazil, Spain, the USA, among others), and has visited the Golden Realm more than once before he met Lara.
 * Lara Croft (voiced by Melanie Minichino) - One of the two core protagonists. A 16-year-old wealthy English teenager and Wimbledon High School top student who aspires to be a notorious archaeologist and treasure hunter like her late father Richard Croft before her, and is friends and roommates with Sonic. While she still wields a pair of dual guns as her main weapons, the guns (to contrast the video games, where they fire lead bullets) fire Ring Bullets, golden bullets which transform into Mobian Rings with the capabilities of opening teleportation portals, immobilizing enemies, etc.

Supporting Characters

 * Gabriel (voiced by Eric Lopez) - An 17-year-old Brazilian teenager who was orphaned by the T-Rex King's assault against a Natla Corporation crew, and raised by the Golden Realm's tribe people. He has ever since grown up to become a skilled hunter. He is Lara's potential love interest.

While he is not close to Lara, her kindness for Sonic proves to be somewhat enough to remind Shadow of his deceased human friend and Professor Gerald's granddaughter Maria.
 * Mari "Cosmo" Corazon (voiced by Katie Leigh) - A 5-year-old Mexican orphan who (due to exposure to an strange alien seed) can communicate with and control plant life.

 * Amanda Everett (voiced by Cassandra Lee Morris) - A 16-year-old American intern at Natla Corporation.

 * Metal Sonic (voiced by Jim Meskimen) - A robotic clone of Sonic created by Robotnik to destroy him, until he rebelled against his creator and begun a crusade to overthrow Robotnik, and take over his technology. He and Lara's Doppelgänger later become the two halves of the Hybrid.

However (due to a few deformities), the Doppelgänger ended up rebelling against her creators and begun partnering with Metal Sonic with the purpose of revenge against their creators, although they still hate their templates. Her deformities also rendered the Doppelgänger mute. She and Metal Sonic later become the two halves of the Hybrid.
 * TBD
