Ep 10. Tanks for the Memories!

In "Tanks for the Memories!," Ash and his friends continue their journey through Sinnoh, heading towards Hearthome City. Along the way, they come across an army base where they witness a battle between two tank-based Pokémon, a Blastoise and a Steelix. The Blastoise, who is owned by a kind-hearted army captain named Tank, loses the battle and ends up badly injured.

Moved by the Blastoise's plight, Ash and his friends offer to help Tank and his fellow soldiers care for the Pokémon. Tank gratefully accepts their offer, and the group sets about helping the Blastoise recover. They learn that the Steelix that defeated the Blastoise is owned by a rival army captain named Rig.

As they work to help the Blastoise regain its strength, Ash and his friends learn about the close bond that Tank shares with his Pokémon. Over the course of their stay at the army base, they also discover that Rig has a deep-seated grudge against Tank, and has been using his Steelix to win battles and humiliate his rival.

Determined to help Tank and his Blastoise get revenge on Rig, Ash and his friends hatch a plan to challenge Rig to a rematch. They also work with Tank to improve the Blastoise's skills and strategy so that it will be able to hold its own in the coming battle.

In the end, the two sides face off in an epic battle, with Tank and his Blastoise finally getting the chance to redeem themselves. Thanks to the help of Ash and his friends, Tank and his Blastoise are able to emerge victorious, finally putting an end to years of rivalry and animosity.

With the conflict resolved and the Blastoise healed, Ash and his friends continue on their journey with Tank's gratitude and friendship.
