Heatmor was used in a battle against Kylan's Mienshao and Watchog while teamed up with Emboar. Mienshao was able to hit Heatmor with Drain Punch but Heatmor countered and knocked Mienshao out with Flame Burst. After Emboar knocked Watchog out as well, Shamus won the battle from Kylan.
Heatmor was then used again in a battle with Emboar against Ash's Snivy and Tepig. Emboar was hit by Snivy's Attract but Heatmor helped him to break out of the attract by using Fury Swipes on him. Emboar then used Flamethrower while Heatmor used Fire Spin, missing Snivy but successfully hitting Tepig. After Snivy dodged the attack, Heatmor was able to hit her by using Fury Swipes. Snivy helped Tepig to gain confidence and it used Flame Charge to attack Emboar and Heatmor. Both Emboar and Heatmor were able to stand up after Tepig's attack, because it did nothing to them, and Emboar used Fire Blitz while Heatmor's Fire Spin surrounded him. The attack was aimed at Tepig but Snivy pushed it out of the away, taking the attack herself, and Emboar knocked Snivy out. After Tepig evolved into Pignite, it used Fire Pledge on Emboar and Heatmor, knocked them both out, and Ash won the battle.
