Chris Thorndyke is the main human kid from Sonic X. He’s a kind-hearted rich kid living in Station Square. He meets Sonic after saving him from nearly drowning in his pool and ends up helping Sonic, Tails, Amy, Cream, and Cheese throughout the series. Chris looks up to Sonic like a big brother and always tries to have his friends’ backs. A semi-high, slightly childlike voice would fit him best.
