In Vs. Spheal, Jynx was chosen to battle Ian's Chimchar. The two clash evenly for a moment, but Chimchar lands a strong Flamethrower. Jynx uses this to power an Avalanche attack, which Chimchar takes with Flame Wheel. The Avalanche causes the ice ground below them to break, leading them to discover an underground ice cave system. The battle is called off as the group goes to explore it.
In Vs. Sheila, Jynx is Sheila's second choice against Crystal, battling her Pachirisu. The two clash for a bit, Jynx having to be wary of Pachirisu's Iron Tail. She then defeated him with a Lovely Kiss/Wake Up Slap combo. She battled Mismagius next, which had a type advantage and avoided Lovely Kiss. Jynx is defeated.
