He has also shown a significant increase in his power and battling skills. Instead of being needy and heavily reliant on Brock's care, Sudowoodo is eager to help Brock in almost any task. In almost all regards, he has grown from a typical baby Pokémon into a strong adult Pokémon, a true testament to Brock's talents as a Pokémon Breeder. He also has an odd tendency to salute Brock whenever he is called from his Poké Ball.

In A Full Course Tag Battle!, he was used in a tag battle along with Ash and his Pikachu against Roman and his Snorlax and Kylie and her Munchlax. He was able to defeat Munchlax with a powerful Double-Edge while Pikachu was able to defeat Snorlax with a powerful Volt Tackle, both doing so in only one hit. Thanks to the great teamwork of these two, Ash and Brock were able to win the battle quite easily.
Brock used Sudowoodo in a battle against a Nurse Joy from the Pokémon Inspection Agency and her Chansey in SS025. However, he was caught off guard when Chansey used Attract. Because of his infatuation, Chansey easily defeated him. It was later seen cheering on Forrest when he battled the same Nurse Joy and helped Brock aid in helping Forrest's Rhyperior recover. Along with Lola's Marill, it serves as playmates of Brock's siblings.
Being much younger than the other Pokémon, Bonsly was portrayed as needy and child-like, and Brock was often seen bottle-feeding him until it could eat solid food. Since his evolution, he has matured and is no longer a crybaby. In fact, he is very upbeat, as seen in All Dressed Up With Somewhere to Go! when he recovered from a crushing disappointment almost instantly.
Bonsly occasionally took over from Max in getting Brock away from girls. However, rather than pull his ear, Bonsly hit him with a powerful Double-Edge. He apparently did not want to share Brock, his "parent."
Since Brock brought another baby Pokémon onto his team by hatching Happiny from the egg he won in the Pokémon Cosplaycompetition, Sudowoodo seems to have bonded with her, and the two frequently are featured doing activities together, almost as if Sudowoodo is an older sibling.
Sudowoodo is the only Pokémon to date that Brock captured onscreen through the standard method by battling it first.
Despite the fact that Brock was specialized to Template:Type2 Pokémon as a Gym Leader, Bonsly was the first new Rock-type Pokémon in his team since his debut, which was 425 episodes before Bonsly was caught.
