Sonic the hedgehog

Sonic the Hedgehog’s social circle is built on a "found family" of diverse allies. As of 2026, his closest bonds remain the "Fast Friends Forever" quartet: Tails (Miles Prower): Sonic's loyal best friend and sidekick. As a mechanical genius, he handles the team's tech while viewing Sonic as an older brother. Knuckles the Echidna: Sonic's fierce rival turned "fighting buddy." The stoic guardian of the Master Emerald, his brute strength balances Sonic’s speed. Amy Rose: A pink hedgehog with an indomitable spirit. Once just a "self-proclaimed girlfriend," she has evolved into a highly capable, independent leader who wields the Piko Piko Hammer. Key Alliances Team Dark: Comprised of Shadow the Hedgehog (Sonic's ultimate rival), Rouge the Bat (a master spy), and E-123 Omega (a battle robot). They often work with Sonic when interests align. Silver the Hedgehog & Blaze the Cat: Powerful allies from different times/dimensions who have frequently teamed up with Sonic to stop cosmic threats. The Chaotix: A detective agency featuring Vector the Crocodile, Espio the Chameleon, and Charmy Bee who provide professional (though often chaotic) assistance.
