Bewear is a very friendly Pokémon who is very fond of Team Rocket. Whenever Team Rocket almost blast off or go missing, Bewear will always find them and return them to her den. In there, she force feeds them honey, which the team finds sickening. She can get extremely happy if offered a present.
Despite her over-affectionate nature, Bewear was revealed to be pretty gentle when she hugged Meowth who was mourning over Stoutland's death in the rain, showing her motherly figure just like how she treated her long-lost child Stufful. When it comes to more dangerous situations, Bewear is very aware and cautious due to having knowledge about the Ultra Beasts' existences, and this was shown by her strength to be on par with the Ultra Beasts’ power levels.
In addition, Bewear detests others from deceiving her. To cite an example, she glared a James and yelled at a high pitch furiously when discovering that Cosmog wasn't the pre-evolution of Koffing. Another instance was when she realized that Team Rocket trio left her behind with robots modeled after themselves and found out that they tricked her after the robots malfunctioned.
In the past, Bewear lost her child, Stufful, whom they got separated, with the latter was found and rescued by Aether Foundation member Wicke, who soon take it to the shelter in Aether Paradise until they found its parent.
Bewear was first seen sleeping when Tapu Koko dropped a berry on her, waking her up. When she encountered Ash and Pikachu, she waved at them. Ash and Pikachu waved back, to which Bewear responded by joyfully crushing some trees. Ash then interpreted Bewear's actions as hostile, and ran away from her with Pikachu. She proceeded to chase the two, though it stopped when Tapu Koko dropped another berry on her. 
Bewear reappeared when she scooped up Team Rocket who were fighting Ash and his classmates.
It is revealed Bewear took Team Rocket to her cave for a meal, actually giving her to them. However Bewear's food supply was cut short as it was taken by a migrating flock of Toucannon, Pikipek, and Trumbeak. In exchange for freedom, Team Rocket agreed to retrieve Bewear's food back for her. However, they partially completed their task, obtaining one net full of food as Bewear got impatient and grabbed the team.
After Team Rocket was defeated, Bewear saved them, taking them away: first by catching them by running top speed over the ocean, and later leaping from roof to roof to retrieve and carry them away from Ash and Pikachu.
Later, Team Rocket attempts to escape Bewear after it constantly force-feeds them honey. They almost end up blasting off for the first time, but Bewear inexplicably appears, soaring through the sky to catch them before hauling them back to its den.
When Team Rocket is contacted by headquarters, James brings up the idea of catching Bewear for the organization, as she is an extremely powerful Pokémon. However, they decide against it after watching Bewear's strength first-hand. Bewear later takes the team away when they are about to defeat Ash's Pokémon. They later decide to make their secret base in Bewear's den due to its hospitality. 
Team Rocket later participated in the Great Alola Pancake Race, where Meowth and Wobbuffet drove a mechanical look-alike Bewear. Just as they were about to reach the finish line, Bewear inexplicably appears and slices through the machine, exposing Meowth and Wobbuffet. Bewear takes them, Jessie, and James, back to the cave, thus ruining Team Rocket's chance to win.
After Team Rocket was frozen in ice statues by Snowy's Powder Snow, Bewear took them back to her home. Then, she became overjoyed when Jessie told her that she would give her the malasadas, causing her to hug her over-affectionately and nearly killed her.
When Team Rocket blasted off for the first time in Alola, Bewear caught them right outside her den.
Team Rocket later played a game of Pokémon Base with the Pokémon school. Even though they lost, Oluolu agreed to give Jessie an autograph. Before Jessie was able to take it, Bewear appeared and snatched Team Rocket, prompting her to yell at her for inconveniently appearing out of nowhere.
Bewear eventually discovers that Team Rocket is missing. She somehow deduces that they are in Kanto, and boards an airplane. When she spots the Meowth robot, she jumps from the plane, crushing the robot. She then leaves with Team Rocket in tow with a machine part attached on her. Later on, the machine part has broken, so Bewear is swimming in the ocean and making her way back to Alola.
Sometime after the recent incident at Aether Foundation involving the pack of Nihilego kidnapping Lusamine, Bewear prevents Team Rocket from kidnapping Nebby, which would have disturbed the Tapu Guardians' ritual to evolve Nebby into a Solgaleo, realizing the dangerous situation ahead of them and Ash's gang.

At some point during the Alola crisis, Bewear prevented Team Rocket's attempt to capture Nebby and Lunala and encouraged them to help join everyone in sharing its light to restore Necrozma's original Ultra form.
During Team Rocket’s second infiltration on Aether Paradise, Bewear arrived to take Team Rocket away from stealing the guarded Pokémon. Thankfully, it happens to be the same time reuniting with her child, Stufful, as the latter manage to smell its mother’s scent on Jessie’s, eventually lead it to the right track. As Bewear takes Team Rocket away with a helicopter’s blade, she let her child to roll it for her. As a debt to repay Wicke for looking after her child for her, she gifted her the Mitsuyoshi honey.
While returning to her den with Stufful, Bewear overhears Jessie’s Wobbuffet screaming for help that Team Rocket’s Z-Crystals were stolen by an Ultra Beast named Pheromosa, who began to use their teammate Meowth as its unwitting pawn for its own scheme to steal Z-Crystals from their respective owners. As Bewear began to investigate the desperation situation across Alola by Pheromosa off-screen, she becomes furious of Pheromosa’s cold nature, and even worst when the latter have no use for Meowth anymore and broke his heart. As Bewear furiously defeated Pheromosa using her instinct to counter its speed, Bewear retrieve Team Rocket’s Z-Crystals and retreat to her den. When Meowth still depressed by Pheromosa’s betrayal, Bewear told him to eat the fruits she brought to forget about that spoiled Ultra Beast who played his heart.
None of Bewear's moves are known.
