Charjabug was a defensive Pokémon when it was in the wild, and this was shown when Ash picked it up from underground. Due to this part of its personality, it wasn't sure of itself until being encouraged by Sophocles who has helped it to gain confidence on itself and it gets warmed up after being around its trainer friends' Pokémon and Togedmaru.
Upon hearing that Sophocles might be moving, Ash sought out this Pokémon as a farewell present. Ash enlisted his team of Pokémon and captured it in a cage. Sophocles' Togedemaru did battle with it, allowing Sophocles to catch it. Sophocles and Togedemaru later encouraged it by letting walk in the hamster wheel.
Charjabug was then seen playing with its Pokémon friends by acting itself like the front cart of a train.
Charjabug was seen eating its food with the other Pokémon after Ash and Mallow returned from Lush Jungle.
Charjabug was later used to take part in a Charjabug Race. However, because of its mild nature, Charjabug is not quite that fast with its energy. So, Sophocles, Ash, and Kiawe helped train Charjabug for the race in order to help it build more confidence. Before the race started, Charjabug and Sophocles was constantly mocked by Hayate, an arrogant trainer who believes that his shiny, red Charjabug's speed-enhancing nature and supreme equipment will win. But Sophocles wasn't worried and had complete faith in Charjabug after all the training they've done. When the race began, Sophocles acted as the team's director while Ash acted as Charjabug's support runner and Kiawe acted as the mechanic. Charjabug, with Ash's help, was able to make it through the race, but Ash was accidentally knocked out unconscious by Team Electric Princess' Charjabug. Sophocles stepped into the race and took over while Kiawe took care of Ash. At the very last minute, Sophocles and Charjabug dashed across the finish line and won the race, winning a yearly supply of Charjabug-themed products in the process.
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.
