Nelson Thorndyke

Nelson Thorndyke (ネルソン・ソーンダイク) is a character in the anime series Sonic X and its comic series published by Archie Comics. He is a human and the husband of Lindsey Thorndyke and father of Christopher Thorndyke. He is the wealthy CEO of Thorndyke Industries, whose company has succeeded well enough for him to be a famous celebrity. Along with his wife, he was able to purchase a beautiful mansion for Chris to enjoy a luxurious life.

New World Saga
In episode 6, he and Lindsey decided to drop by at their home for a visit to see their son. When Chris took a while to return home, they start to feel worried.

Chaos Emerald Saga
He briefly appears in episode 20 to suggest a cruise to the glaciers as means for relaxation after being tired from the heroes' numerous battles with Doctor Eggman. He later appeared in the following episode along with his wife as sponsors for the race Sam Speed and Sonic are about to partake in. Later, he stopped by a jewelry store to find a ring to give to Lindsey as an wedding anniversary gift, and happened to find the purple Chaos Emerald. Seeing it as the perfect ring for Lindsey, he purchased it and then had Chris come to Filmdom City with Chuck, their staff, and Sonic with his friends to be part of the surprise with when he presented the ring to Lindsey. However, the plan fell apart when he tripped as Lindsey approached and she discovered it was him in place of her co-star, and the Chaos Emerald wrecked the sound stage when it reacted to the ones carried by Sonic and Knuckles. Lindsey and Nelson got into an argument that even Chuck could not break up, but it was brought to an abrupt end when Eggman crashed the set, and in the confusion, Rouge stole the Emerald from Nelson. When Eggman unleashed E-74 Weazo against the Thorndykes, Nelson attempted to protect Lindsey and Chris from the robot beast. Once Sonic and Knuckles destroyed E-74, Nelson is relieved to find Lindsey and Chris unharmed, and the wedding anniversary celebration goes on without further problems, though not quite as Nelson had originally planned.

Emerl Saga
Nelson took part in a Chaos Emerald Martial Arts Mash-Up tournament, whose main prize was a Chaos Emerald.

Homebound Saga
When Chris ran away in the episode before Sonic the Hedgehog 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.

Metarex Saga
While Chris was on the Blue Typhoon in Sonic's world, the remaining Thorndykes tried to find a way to teleport to Sonic's world and look for Chris when his wife Lindsey gets worried about him. Nelson states that Chris can handle himself and doesn't need to come back, so they agreed to send items that may help Chris through Vanilla the Rabbit and the Chaotix.

Personality
Though he is very busy with his job, Nelson often tries to spend time with Chris and be the best father for Chris as he can. While very composed, he tend to overreact when worried, but will act afterwards as he had remained in control of his worries.
