From Sonic Retro
Nelson Thorndyke is a character from the anime series Sonic X, he is the father of Chris Thorndyke, the husband of Lindsey Thorndyke, and the son of Chuck Thorndyke. He is also the owner of a computer and housing business.
Although he is very busy with his computer company, he often tries to spend time with Chris. He also tries to be the best father for Chris as he can. When Chris ran away in the episode before Sonic and friends return to their world, Nelson thought the best way to make Chris come home was to buy him a whole toy store, but he did a TV broadcast instead. Sometime later, they searched on foot and found Chris and Sonic at a seemingly abandoned log cabin. While Chris was on the Blue Typhoon, the remaining Thorndykes tried to find a way to teleport to Mobius and look for Chris. They sent his stuff instead.
He is voiced by Ted Lewis in the English dub of the anime.
