New World Saga
When Sonic and his friends arrived at Thorndyke Mansion, Tanaka discovered them long before Ella did. However, he this secret to himself. Some time later, Tanaka caught Chuck running around with Chris. Insisting that the elderly Chuck took easy, Tanaka forced him to go take a nap. Tanaka would not long after receive a call from Nelson Thorndyke, saying that he would and his wife would come home for a visit. Bringing these news to Chris, Tanaka and Ella grew suspicious when Chris did not seem happy about it. Regardless, Tanaka gladly welcomed back Nelson and Lindsey when they arrived. When Chris did not come home from school as planned however, Tanaka thought about going out to look for him, but Ella had him dismiss that thought. After Chris finally came home though, Takana was able to serve the Thorndyke family's dinner.
Eventually, Tanaka revealed his knowledge of Sonic and co. to Chris when he found him scolding Cream the Rabbit. However, since Ella did not know about it yet, Tanaka agreed to keep it a secret for as long as possible. He therefore helped Chris cover for Sonic's friends when they made their made an appearance during a party. When the chaos from this incident got to Ella though, Tanaka helped convince Chris to let Ella in on Sonic and his friends. Some time after, Tanaka discovered the TV signal was gone, which was the result of Dr. Eggman's E-90 Super Sweeper sucking up satellites. Tanaka later took noticed when Eggman's private television broadcast got interrupted by Sonic.
Tanaka later escorted Chris when he traveled to Emerald Coast to oversee the opening of Hotel de Blanc there while Sonic and his friends stayed at the Thorndykes' bungalow. When Eggman invaded the holet grounds with his robots however, Tanaka took a stance to protect Chris, but was held back by Ella. Fortunately, Sonic and Amy soon showed up and drove Eggman off. Tanaka was later teaching Sonic and his friends good table manners when Bokkun arrived with a message from Eggman, who alerted them to the appearance of a Chaos Emerald and challenged them to a game of baseball for it. Arriving at Diamond Stadium, Tanaka joined Sonic's team, who would be facing Eggman's team of E-21 Ballios. At the end of the game, Eggman fled with the Emerald, although the good show Tanaka and his friends had put up allowed the decommissioned Diamond Stadium to remain in business.
Chaos Emerald Saga
When presidential aide Jerome Wise came to the Thorndyke Mansion to get Sonic for a meeting at the White House, Ella was unable to convince Wise and his accompanying agents to leave. As such, she summoned Tanaka, who forced the agents into leaving by overpowering them with his martial arts. When the Egg Fort later attacked Station Square, Tanaka took it upon himself to bring the X Tornado to aid Sonic, Tails, and Chris via a semi-truck.
After presenting Sonic and co. with their own official passports, Tanaka bid farewell to Chris, Sonic and their friends when they went on a vacation to the Sapphire Sea. Following the request Chuck however, Tanaka secretly followed them to ensure Chris would stay safe. Arriving in the Sapphire Sea, Tanaka arrived with a large boat for Chris and his friends to use, just as they were battling Eggman's E-57 Clurken. Later, at the behest of Nelson, Tanaka brought some senior citizens from the Silver Star Retirement Home on the cruise Chris and his friends were on so the senior citizens could teach the group of heroes how to relax. Chris inisted that they only asked for lift to get the stir-crazy Sonic back to the mainland, but Tanaka insisted that Sonic, as a warrior, needed to learn how to relax. After Chris and co. returned home, Tanaka and Ella would in the middle of the night attack an intruder on the Thorndyke property, only to discover that it was Sam Speed, who wanted to challenge Sonic to a race in his new Rocket Car. Tanaka would subsequently observe the race between Sonic and Sam (after Sonic was "persuaded" to compete) as a spectator. In the end, Sonic won the race by a landslide.
Later on, Tanaka took Chris and some of his classmates with him on a field trip back to his homeland of Japan. He remained at camp with Amy and Mister Stewart while the kids were off with Tails, Cream, and Cheese enjoying themselves. Later on, when they learned of Eggman being in the area, they warned Sonic about it. At the campfire later on, Tanaka learned that the kids had found a Chao colony and revealed that he knew about it.
Some time after, Tanaka was summoned to Filmdom City by Nelson, as part of a plan to surprise Lindsey on their wedding anniversary, and discovered that the wedding ring Nelson got Lindsey was actually a Chaos Emerald. When Nelson's plan fell apart and the Emerald began reacting violent with the other Emeralds in the vicinity, Tanaka was able to subdue it and suggest taking the Emerald somewhere safe before Lindsey got into an argument with Nelson over trying to ruin her latest movie. When Eggman then crashed the sound stage in the Egg Fort II and acquired Nelson's Emerald, he unleashed E-74 Weazo to attack the Thorndykes. Tanaka tried to confront the E-Series robot himself as part of his duty to protect the Thorndykes, but E-74 easily swatted him aside. Though Sonic and Knuckles took down E-74, Tanaka felt he had failed his duty and dishonored himself, but Chris and Lindsey assured Tanaka they were still proud of him and want him to remain as a member of their staff. Tanaka then took part in the celebration afterwards.
On a day following Sonic's battle with Eggman's E-88 Lightning Bird, Mister Tanaka was going to the car, unaware that Sonic had gotten a microchip from E-88 stuck in his ear. When Tanaka used the car's remote control to unlock it, it activated the microchip and caused Sonic to run non-stop until he got the chip out of him.
Over six months later, Tanaka saw Sonic and Tails take off in the X Tornado to rescue Amy from Dr. Eggman. He also assured the worried Chuck that Sonic and Tails had this crisis under control. Back in the Thorndyke Mansion some time later, Tanaka watched a news report with Tails and the others that detailed Tails' heroic efforts in stopping a missile from destroying Station Square. When Tails then needed to get unseen through a crow of grateful citizens outside the mansion, Tanaka and Ella helped the fox cub by disguising Tanaka like a baby that Ella was taking out for a walk, which distracted the crowd while they snuck Tails past them.
When Perfect Chaos launched its flooding of Station Square, Mister Tanaka remained behind to wait for Chris at the mansion while Chuck, Ella, Cream, and Cheese evacuated, determined to save Chris from the flood waters if needed. After they left, Tanaka took a meditative state as he prepared for the worst.
Egg Moon Saga
Tanaka is calm, composed and very dedicated to his job. He cares very much for the well-being of Chris and his family and has risked life and limb for them on several occasions.
In the English dub, he speaks with a stereotypical Japanese accent.
Powers and abilities
Mr. Tanaka is a skilled martial artist (though in the English dub, this is apparently because he watches "too many Kung Fu movies").
Sonic the Hedgehog
Even though he is a good friend of Sonic the Hedgehog, Sonic holds him in low contempt and does not like it when he goes on adventures with him, believing that he is not useful. This may be because he usually hinders Sonic more than he helps when he tries to assist Sonic.
- The French dub of Sonic X switches between the usual Tanaka name and "Édouard". It is likely that his name was intended to be completely localized in this language, but the translators may have been sloppy with their efforts.
