Big the Cat is a large, fictional anthropomorphic purple cat from the Sonic the Hedgehog series. His character designers may be either Yuji Uekawa, Takashi Iizuka or even Naoto Oshima. Though both physically strong and imposing of stature, Big is a gentle and easy-going, though somewhat dim-witted, person with a heart of gold.
Big resides deep within the Mystic Ruins, where he spends most of his time fishing in tranquility with his best friend Froggy. Big is not one for going on grand adventures, preferring his peaceful and quiet lifestyle in the jungle. However, should his friends be in danger or in need of his aid, Big will not hesitate to help out and protect them in any way he can.
