Chris Thorndyke is a human from the alternate planet Earth in the Sonic X Zone. A generous boy from a wealthy family, he met Sonic the Hedgehog after rescuing the latter from drowning in his swimming pool, before allowing him and his friends to take refuge at his family mansion until they can find away to return to their home planet. Despite his lacking in any notable abilities, he still does whatever he can to help Sonic and friends battle Dr. Eggman.
Chris has lived in Station Square for most of his life. From a young age he mostly lived under the care of his grandfather Chuck Thorndyke, along with his mansion's servants Ella and Mr. Tanaka, due to his successful parents often being away. Although Chris was always showered with love and care from his guardians, he had a considerably lonely childhood, brought on by the constant lack of his parents as he grew up. His life took an unexpected turn one night when Sonic the Hedgehog landed in his backyard swimming pool. After Chris dove in to rescue the hedgehog from drowning, he instantly befriended him, allowing him and his friends, who had ended up on Earth from their home world through Chaos Control, to live with him at his mansion.
