Going to Daybreak Town, Ursula raised Plusle and Minun for that Contest. She encountered Dawn, who didn't want to see Plusle and Minun out of her personal trauma. Ursula called her rude, to which Plusle and Minun tried to cheer her up. However, they electrocuted her by accident, causing Dawn to faint. During her battle against Jessilina, Ursula's Plusle and Minun faced her Yanmega and Seviper in a Double Battle. Seviper emitted Haze, while Yanmega fired Sonic Boom. Plusle and Minun held their hands together as they used Spark to negate these moves. Yanmega lifted Seviper in air, whereas Plusle and Minun used Helping Hand to boost each other. Yanmega's Silver Wind fused with Seviper's Poison Sting to strike Plusle and Minun, who used Seviper to stop it. The two Pokémon attacked Seviper and Yanmega. As time was up, Ursula won the battle as she lost less points than Jessilina did.
In the final battle of the Contest, Ursula faced Dawn, using her same Pokémon against Dawn's Cyndaquil and Mamoswine. Mamoswine fired Ice Shard and Cyndaquil emitted its flames to give it a fiery glow. Mamoswine then used Ice Shard to increase its power as Cyndaquil fired Swift around it. Cyndaquil went atop of Mamoswine, who used Take Down, but Plusle and Minun dodged. The latter two used Encore. This prevented Dawn from ordering her Pokémon to use Hidden Power and Flame Wheel: instead, Mamoswine continued to use Take Down and Cydaquil fired Swift, due to Encore's effect. Plusle and Minun dodged and used Helping Hand at one another, firing Charge Beams to strike Mamoswine and Cyndaquil.
As Plusle and Minun used Spark on Cyndaquil and Mamoswine, the latter two were still under the effect of Encore and repeated their moves. Plusle and Minun continued using Spark to electrocure Mamoswine and Cyndaquil, and caused Dawn's hair to become messed up. To reverse the situation, Mamoswine used Take Down on Cyndaquil, and the latter fired Swift on the former. This caused Encore to be worn off, allowing them to evade Plusle and Minun's Charge Beam. Mamoswine fired Ice Shard on Cyndaquil, whose Flame Wheel powered it up and redirected it on Plusle and Minun, dealing damage to them. Plusle and Minun attempted to retaliate with Spark, but were stopped by Cyndaquil's Smokescreen, and were damaged by Hidden Power and Swift. As time ran out, Dawn retained more points than Ursula had and won the battle.
Arriving to the Grand Festival, Ursula had Minun and Plusle electrocute Dawn a bit to startle her.
Ursula also appeared in the ending scene of the 13th Pokémon movie, along with her Plusle and Minun.
