Rosa used her Serperior in her battle against Cheren and his Stoutland. Serperior used Hyper Beam but Stoutland used Protect to block the attack. When Stoutland went to use Bite, Serperior nullified the attack by using Slam. It then used Frenzy Plant while Stoutland used Hyper Beam to counter it. Serperior used Protect to protect itself from the Hyper Beam attack.
