Big is from the País Misterioso, otherwise known as the “Mysterious Cat Country.” He never cared much for Felidae customs and was something of an outcast, spending his time fishing in the jungle with his best friend Froggy, a Mobini frog. When Froggy swallowed the tail of Chaos and was captured by E-102 Gamma, Big set out to rescue his friend and explored the Mystic Ruins until he found Dr. Eggman’s Egg Carrier, which he accidentally boarded. He fished out Froggy from Chaos and escaped on the Tornado, which led to a meeting with Sonic, Tails, and Knuckles. Big went with them to Station Square and helped save the city from Perfect Chaos and Silver Sonic II.

While Big elected to remain in Soumerca he occasionally visited his friends in Knothole. He encountered Sonic again when he entered the Wolf Pack Nation looking for the Ancient Onyx, which had been stolen. Sonic and Big met with Queen Hathor and explained the situation, but Hathor as a condition of their arrangement banished the “heathen” Big from their lands. The cats and wolves banded together to defeat the local Dark Egg Legion chapter that had stolen the Onyx, with Big helping to defeat the Grandmasters Drago Wolf and Razorklaw and saving Princess Sally. For his actions Big was named an honorary member of the Wolf Pack.

Big accompanied his friends back to New Mobotropolis where he lived as a civilian. He helped protect citizens during Titan Metal Sonic’s attack and volunteered to join Rotor’s Team Freedom to protect the city from Eggman’s forces, such as the Tails Doll. Big later fought to stop the Egg SWATs from overrunning the city, rescued the injured King Naugus, and defeated Metal Amy. Big then joined the other members of Team Freedom in stopping the rampaging Tails Doll monster.


Big is a simple man with simple needs. He prefers to spend his days fishing without a care and hanging with his best friend Froggy, but when he is more than willing to step up to the plate and help out. Big is kind and gentle but isn’t afraid to get his hands dirty if it means protecting people from those who are being “mean.”
