It appeared in it's final stage as Conkeldurr in The Clubsplosion Begins! and was revealed to have evolved prior to this episode.
In Searching for the Clubultimate!, he battled Bianca's Emboar in the preliminary matchups. He easily blocked all of Emboar's attacks, and then used his concrete pillars to smash him with Strength. It then used Bulk Up, followed by Rock Tomb, to both damage and trap Emboar. Emboar tried to brake free with Arm Thrust, but it was useless. As the episode ended, Conkeldurr launched a powerful Stone Edge on an exhausted Emboar to seemingly end it. In the next episode, Emboar survived the hit and tried to throw the stones back. Conkeldurr still maintained control of the battle and batted them back, hurting Emboar, but he came through and snatched Conkeldurr's concrete pillars. He was then easily defeated when Emboar threw the pillars back with Fling.
Though Conkeldurr has an impressive moveset, he has an extremely low endurance for all its battles; it was defeated by one attack. As a Timburr he was defeated by one razor shell from Ash's Oshawott. As a Gurdurr it was defeated by one rock slide and slash attacks (each). As a Conkeldurr it was defeated just by having its pillars thrown at it. And in all three battles he remained untouched for most of it and did major damage to the foe throughout most of the battle, but lost horribly in the end.
Furthermore, every loss was because he got seperated from his weapon, a wood/steel/concrete pillar(s). As a Timburr he left it to use DynamicPunch, as a Gurdurr, he was unable to reach it due to Rock Slide containing him, and as a Conkeldurr they were snatched away from him.
