Multiverse Unity: Sonic and the Tomb Raider

Sonic and the Tomb Raider is an American English animated television series airing on Netflix, and a crossover between the Sonic the Hedgehog and Tomb Raider franchises.

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 favors and purposes.

Main Characters

 * Sonic the Hedgehog (voiced by Robbie Daymond) - One of the two core protagonists. A 15-year-old anthropomorphic blue hedgehog 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.
 * Lara Croft (voiced by Melanie Minichino) - One of the two core protagonists. A 16-year-old wealthy teenager 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 is Lara's potential love interest.
 * Sally Acorn (voiced by Felicia Day) - An 14-year-old anthropomorphic female Mobian chipmunk from Mobius, and Sonic's girlfriend. She is also a resident of the Golden Realm, where she and Tails established a secret base of science and technology to help the island's local tribe.
 * Miles "Tails" Prower (voiced by Tara Strong) - Sonic's best friend in Mobius, and 8-year-old twin-tailed anthropomorphic yellow fox who can fly by spinning his two tails. A scientific genius and inventor, he is one of the designers of Lara's Ring Guns.
 * Zip (voiced by Zeno Robinson) - One of Lara's closest friends and a 17-year-old Tech Expert.

Initially having no actual form of her own, she was able to create a complex holographically simulated body-based on that of a Mobian lynx projected from her hand-held thanks to a Power Ring.
 * Winston Smith (voiced by Robin Atkin Downes) - The Croft family butler and chauffeur, who is loyal to Lara.

Antagonists

 * Larson Stone (voiced by David Kaye) - The show's overall primary antagonist. An enigmatic criminal who is masquerading as an ally for both Robotnik and Natla for his own favours and purposes, and is manipulating them both against each other. The character is an amalgam of Larson (from Tomb Raider: Anniversary) and Agent Stone (from the 2020 Sonic the Hedgehog movie).
 * Dr. Robotnik (voiced by Clancy Brown) - One of the show's primary antagonists. Sonic's arch-nemesis and the corrupt CEO of Robotnik Industries, who obsesses with absolute power. He is rivals with Natla. Having been banished to the Mushroom Planet following Sonic's battle against him in San Francisco, Robotnik relocated his headquarters and company in there so he may continue plotting his schemes and is revenge on Sonic.
 * Orbot (voiced by Kirk Thornton) and Cubot (voiced by Wally Wingert) - Robotnik's main robotic henchmen, Orbot (the red orb-shaped robot) is the blunter, more formal of the two, often being totally honest even at Eggman's expense. Cubot (the yellow cube-shaped robot) is the slower, more dimwitted of the two, often misunderstanding the meaning of other characters' statements.
 * Jacqueline Natla (voiced by Nika Futterman) - One of the show's primary antagonists. The corrupt head of Natla Corporation who seeks to end the Croft legacy. She is also rivals with Robotnik. Natla also carries a terrifying secret associated with the legends of Atlantis, and Lara and her friends are the only ones who know.
 * Amanda Everett (voiced by Cassandra Lee Morris) - A 16-year-old American intern at Natla Corporation. She strongly dislikes Lara and her family, and sides with Natla to witness her downfall, but is unaware of her boss' true motives and nature, as Natla discreetly regards Amanda as "nothing more than a pawn in a game she does not know is being played".
 * Jerome "The Kid" Johnson (voiced by Sam Riegel) - The leader of an unnamed inner-city gang in Los Angeles, California, who secretly works for Natla.
 * Kold Kin Kade (voiced by Dave Fennoy) - Natla's bodyguard, and a mutated former prison convict with brute strength and long stamina.
 * Snively Kintobor (voiced by Steve Blum) - Robotnik's estranged nephewand former loyal assistant, who plans to usurp him in revenge of Robotnik's abuse of him.
 * Regina Ferrum the Iron Queen (voiced by Mary Elizabeth McGlynn) - Snively's lover, and a rogue Atlantean witch with the ability to manipulate metal.
 * 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.
 * The Deadly Six - A clan of ruthless Zetti from the Lost Hex organized by Master Zik and led by Zavok.
 * Zavok (voiced by Jonathan Adams) - The leader of the Deadly Six. He obsesses with stealling technology from both Robotnik and Natla, which he plans to use for a weapon to drain Earth and Mobius of their energies, and empower the Lost Hex.
 * Zenna (voiced by Cree Summer) - A fashion-savvy Zeti and the only female member of the Deadly Six.
 * Zazz (voiced by Richard Steven Horvitz) - A hyperactive, but psychotic Zeti and member of the Deadly Six.
 * Zor (voiced by Sam Riegel) - A existentially nihilist Zeti and member of the Deadly Six.
 * Master Zik (voiced by Andrew Kishino) - The founder and former leader of the Deadly Six.
 * Zomom (voiced by Bill Fagerbakke) - A obese dim-witted Zeti with an eating disorder and a member of the Deadly Six.
 * The Doppelgänger - Lara's identical clone, created by an Atlantean witch under Natla's secret orders for the purpose of framing her. 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, for which Metal Sonic occasionally speaks for her.
 * TBD

Anti-Heroes

 * The T-Rex King - A male Tyrannosaurus Rex from the Golden Realm, where he is considered the most feared predator. He most occasionally pursues Sonic and Lara (just like anyone who steps on the Golden Realm), but most rarely becomes their ally whenever they defeat him.
 * Shadow the Hedgehog (voiced by Adam Baldwin) - A 50-year-old anthropomorphic black hedgehog who was created by Robotnik's grandfather Professor Gerald to be the "Ultimate Life Form", a lifeform capable of curing any disease. A immortal speedster of Sonic's level, he is part-time rival and part-time ally to Sonic, depending of his goals. 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.
