Like Dawn's Pachirisu, Togedemaru is really playful and hyperactive. She is also helpful when using her Lightning Rod ability and she can also have a bit of a temper, as shown in Racing to a Big Event! when she got upset with Sophocles for losing the Pokemon Pancake Race.
Like Dawn's Buneary, Togedemaru is shown to have a crush on Ash's Pikachu which is shown when she would jump on Pikachu and try to hug him.
The next day, Sophocles had Togedemaru run on a wheel to power up his program. Then, Sophocles challenged Ash and Pikachu. They were both piercing balloons as a challenge. Pikachu went to use Thunderbolt, but Togedemaru absorbed the attack with Lightning Rod. Next, Togedemaru used Zing Zap and spinned around to pierce the balloons, making Sophocles the winner of the challenge. Togedemaru was with her trainer, who went with Ash to see what new Pokémon he would catch in the forest. Togedemaru also watched as Team Rocket appeared, who threatened to steal all their Pokémon, and how they were dragged by a Bewear. After Ash's Pikachu got hurt in a battle against Grubbin, Togedemaru went with her trainer away to report to Professor Kukui what happened. Togedemaru went with her trainer to go fishing and watched as Ash and Lana were rescuing the Pokémon Team Rocket stole.
Sophocles went with Togedemaru to the Melemele Island's mall. There, they encountered Ash, who was going to buy some groceries. Togedemaru tackled Pikachu and tried to hug him, showing her affection towards him. Togedemaru curled herself and started rolling and accidentally bumped into Ash, due to her excitement. After having some ice cream, the group went through the mall. Suddenly, the security system was triggered, causing Ash and Sophocles to be split from Pikachu, Togedemaru and Rotom. Since neither side could bash the door, they decided to go to the power supply room. Pikachu and Togedemaru followed Rotom, who showed a vent shaft they could go through to the room. Since Togedemaru couldn't climb, Pikachu offered to help her get up. Surprisingly, Togedemaru was already at the vent shaft, which surprised Pikachu, who fell down, but quickly went back up. After exiting the shaft, the Pokémon faced Team Rocket, whose Mimikyu started to attack Pikachu. One of Mimikyu's Shadow Ball attacks nearly hit Togedemaru, so Pikachu took the hit and was blown away onto the next building's window. Once Ash and Sophocles arrived, the latter had an idea and tell the former order Pikachu to use Thunderbolt. Pikachu did so and Togedemaru absorbed the attack with her Lighting Rod ability, allowing her to use Zing Zap to electrocute Team Rocket. After Team Rocket was taken by Bewear and Pikachu was rescued by Ash's Rowlet, Togedemaru started showing her affection on Pikachu again, trying to hug him. Sophocles also mentioned Togedemaru was a girl, while Ash remarked how powerful their teamwork was. Later, Togedemaru went with Sophocles and Ash, who encountered Professor Kukui and his Rockruff, the former promising to take them all to the restaurant.
The class spoke about the Rattata and Raticate problem and found out the solution were Yungoos and Gumshoos. Their yelling startled Togedemaru, who ran in circles and knocked Lana's Popplio and Mallow's Bounsweet off the table. Pikachu managed to stop and calm her down, but Togedemaru started showing affection towards him. Togedemaru, along with her trainer, was at the party to celebrate Ash and his Pokémon's Grand Trial of Melemele Island victory. Sophocles and Togedemaru spent a day on the beach with Sophocles' classmates. Togedmaru played with Sophocles in the water. She also went to hit the bubble in volleyball, but failed and fell into the sand. Sophocles and Togedemaru enlisted for the Pokémon Pancake Race. Since Sophocles dropped pancakes in the balance course, he was disqualified from the race. Sophocles went to tell this to Togedemaru, who became furious and extended her spikes to punish Sophocles.
The next day, Togedmaru watched as Lillie's egg hatched into a white Vulpix and Samson Oak's egg into a red Vulpix. While the white one, Snowy, ignored the group, the red one wanted to play with the others. The next day, after Lillie befriended Snowy and hugged it, Snowy was more interested in playing with the class's Pokémon. Sophocles and Togedemaru were at class when Ash explained how Rockruff came to the house wounded the other night. Popplio emitted a bubble, which splashed Bounsweet, Pikachu and Togedemaru. They also watched Ash train Rockruff. Togedemaru and Sophocles went to DJ Leo's concert and she was seen dancing happily. Later, Steenee, Rockruff, Togedemaru and Pikachu befriended DJ Leo's Diglett, who deeply admired Jessica, Ashley, and Michael. Togedemaru was playing with Pikachu during and after school. She was also training on the wheel with Pikachu and others. Later, during Ash and Pikachu's battle with Tapu Koko, Togedemaru protected her trainer and the group from an oncoming Discharge attack with its Lightning Rod ability. Finding that Ash was captured inside a Pallossand, Sophocles and Togedemaru helped Lillie's Snowy in using Powder Snow to freeze Pallossand.
Sophocles worked on a program involving Togedemaru. As he went to eat something, he heard he and his family would have to move. Sophocles was terrified and, during the night, explained this to Togedemaru. Since Togedemaru didn't quite understand, Sophocles showed a video where she would be separated from Pikachu, making her cry. The next day, Togedemaru started weeping and crying to Pikachu. Others wondered what was going on, though Sophocles assured them that was a way Togedemaru expressed her fondness to Pikachu. Just as Sophocles went home, he encountered his friends, who wanted some explanation. Sophocles told them he was moving, so his friends wanted to give him a good time before he moved away. Kiawe took Sophocles and Togedemaru on his Charizard, to a volcanic lake on Akala Island, which impressed Sophocles and Togedemaru. As the two came back home, Sophcoles was told that they were only moving to a next house to repair their own house. Sophocles couldn't do much but to hang out with his friends until he could tell them the truth. After Lana showed them the sunset and a Wailord diving into the ocean, Sophocles and Togedemaru came to Aina Cafeteria. There, Ash came with a Charjabug, as a present to Sophocles, who had his Togedemaru fire Discharge to weaken and capture it. Sophocles was moved by this and started crying and apologizing, since he was mistaken about moving elsewhere. His friends were actually relieved he was not moving, and Sophocles showed Togedemaru they were not really moving. Togedemaru was ecstatic and started jumping and electrocuting everyone in happiness.
During the Pokébase match, Togedemaru was a part of Ash's team. During the match, Togedemaru ran and extended her spikes to catch the ball. While going out camping, Togedemaru relaxed in the river. Due to Morelull's presence, Togedemaru fell asleep and was drained, along with others, except Lillie. Instead, everyone had dinner to end their hunger. Not soon after, the group encountered the Morelull, who, once again, made them asleep and drain them. Ash gave some of the energy to feed Morelull, and consecutively ate the curry Mallow made. Morelull was fed up and went to the tree, where everyone, including Togedemaru, watched as the Morelull evolved into Shiinotic. The Shiinotic Ash fed turned them asleep. The next day, however, everyone woke up and found themselves not hungry at all, seeing that Shiinotic returned the energy it drained from them. Before the class started, Togedemaru had a race with other Pokémon around the room, a race Pikachu won. During the Pokémon exchange at School, Togedemaru was paired up with Mallow. At Aina Cafeteria, Togedemaru was too excited and started knocking tables and other guests, giving Mallow a lot of trouble. The next day, however, Togedemaru knocked a can and some rags, then started rolling around. Mallow was amazed and encouraged Togedemaru to continue, as she was actually cleaning the floors. The day after, Togedemaru showed its affection to Mallow, who noted Togedemaru really loved the Cafeteria's food.
Olivia, who came to the Pokémon School, wanted to meet the heroes' Pokémon, and met Sophocles' Togedemaru. As the class went to find an item and bring it to Olivia, Togedemaru accompanied Sophocles on that task. Sophocles and Togedemaru went to Kiawe's farm, where they had a tasty ice cream. Sophocles asked Kiawe to bring more ice cream for them, even if Kiawe asked of them to help him in doing chores.
During the group's field trip to Cerulean City, Togedemaru fought alongside with Snowy in a battle against Brock's Geodude. Togedemaru used Zing Zap on Geodude, but failed due to it being part Rock-type.
Later, when the group traveled in Ultra Space, Steenee, Popplio, Togedemaru and Charjabug along with Litten and Rowlet were sent out to battle Lusamine's Mismagius, Milotic and Lilligant.During the battle, Charjabug and Togedemaru used a Discharge-Zing Zap combo to defeat Milotic. But even though it looked like they successfully defeated it, Nihilego made it stand back up again. The battle ended with Ash and Pikachu defeating Nihilego with the 10,000,000 Volt Thunderbolt Z-Move, which sets all of Lusamine's Pokémon free.
Sometime later, Togedemaru helped Sophocles and his classmates complete several Ultra Guardian missions and helped Ultra Beasts return home.And in the process it meets a new friend who is also an Ultra Beast, Ash's Poipole.
Togedemaru and Charjabug were listening to Sophocles' story when they saw Celesteela and together they tried to dig it out. Later, when Sophocles and his friends were trying to dig out Celesteela, Charjabug called the Grubbin in the forest for help and sped up the process.
