In Chim - Charred!, Ursaring was used in a battle against Chimchar, who, by that point, had come under Ash's ownership. With its brute strength and power, it almost defeated Chimchar when he activated his BlazeAbility. However, after Chimchar lost control of Blaze, he defeated Ursaring.
In Evolving Strategies! Ursaring was used in the Full Battle against Ash as Paul's sixth Pokemon, which took place at Lake Acuity. With the power of Bulk Up, it easily defeated Ash's Buizel and Staraptor before being recalled. During the battle with Pikachu, it got paralyzed by Pikachu's Static Ability. However, this, in turn, activated its Guts Ability, giving the Hibernator Pokémon the power that it needed ultimately take Pikachu down. Ursaring was eventually brought down by Chimchar once again after being attacked with a Flamethrower.
Like most Ursaring, Paul's Ursaring was shown to be aggressive and hostile toward everyone, often screaming when exiting its Poké Ball. This has led to others being intimidated by it and cowering in fear. Paul has never shown any concern with Ursaring's personality, often encouraging its violent behavior.
It is an extremely powerful battler, being able to use its Guts Ability effectively as well as defeat strong opponents with relative ease. These traits were both shown when it single-handedly beat half of Ash's team during Ash and Paul's Full Battle at Lake Acuity and when it defeated Barry's Hitmonlee. Ursaring has a high amount of stamina and resilience.
