Solid as a Solrock (Japanese: トクサネジム！ソルロックとルナトーン！ Mossdeep Gym! Solrock and Lunatone!) is the 8th episode of Pokémon: Advanced Battle.
Once again, the time has come. Ash will have a double battle against the terrific twins, Tate and Liza. As the battle begins he sees they don't get along very well and the battle could be an easy win for him, that is until Team Rocket interferes and snatches Lunatone and Solrock. After thwarting their latest plot Rachel suggest that Ash and Liza and Tate continue their battle, even though the Gym is destroyed they could have it on the cliff. As the rematch begins Liza and Tate are more in-sync than ever. Will Ash be able to beat them this time? The answer might shock you.
Ash has his Gym Battle. Tate and Liza's mom explains the rules. Brock, May and Max comment the battlefield, as it is not something Ash was used to. Ash sends Pikachu and Swellow. Tate sends Solrock and Liza her Lunatone. Jessie and Jams appear before the Gym, planning on stealing Solrock and Lunatone. Jessie and Meowth go, but James reminds them that without a plan they'll fail. So, Meowth thinks that the machines ought to do the capturing.
Solrock and Lunatone tackle Pikachu and Swellow. Pikachu uses Quick Attack on Solrock and Swellow Peck on Lunatone, though both Pokémon miss and crash on the planet models. Lunatone attacks with Ice and Solrock with Solar Beam, but before they hit them, the beams crash into each other and are negated. Tate and Liza begin to argue. Swellow uses Aerial Ace, giving a hearty push to Lunatone, while Solrock is damaged by Pikachu's Iron Tail. Lunatone and Solrock go to tackle Pikachu, but both crash into each other when Swellow carried Pikachu away. Liza and Tate argue more, so Brock thinks Ash will have more chance to defeat them. Ash goes to give orders to Pikachu and Swellow, but...
... but Team Rocket arrives to the scene with a gigantic robot. Solrock and Lunatone go to attack, but they are captured inside the cages. Solrock and Lunatone use Psychic, but fail, as the cages prevent themselves to be opened. They go away, but the gang follows them. Mewoth pushes a button, so the balloon grabs the robot and they go away. Pikachu uses Thunderbolt, but the robot is too far away. Team Rocket is happy they finally catched something. Pikachu goes on Swellow's back, though Team Rocket releases the glue bombs (to which they evade). Pikachu uses Thunderbolt, damaging the machine and setting Solrock and Lunatone free. Solrock and Lunatone use Psychic, exploding the robot and blasting Team Rocket off.
Ash feels sad that his Gym battle is ruined, but Tate and Liza say they can battle here, so Ash agrees. The battle continues - Pikachu attacks Solrock with Thunderbolt, but Lunatone goes in, using Light Screen to deflect the attack to Pikachu. Swellow goes to use Aerial Ace on Lunatone, but Solrock protects Lunatone, using Sandstorm to wound Swellow. Ash orders Pikachu to go on Swellow's back. Pikachu attacks with Thunderbolt, but Lunatone uses Light Screen, deflecting the attack to Swellow and Pikachu. Swellow and Pikachu still stand, so Swellow uses Double Team, reproducing illusions of it and Pikachu. Solrock uses Solar and Lunatone Ice Beam to hit the illusions. However, after destroying the illusions, they see nothing, but Swellow dives. Quickly, however, Solrock and Lunatone attack them, but in an instant, Swellow gains balance.
Ash tries to find another strategy, and comes up with a one. Pikachu uses Thunder, though he aims at the clouds, reflecting the attack at themselves. When the attack is done, everyone sees a "golden" version of Pikachu and Swellow. Swellow uses Quick Attack, while Solrock uses Solar Beam. Solar Beam hits them, but with little difference. Lunatone goes to use Light Screen, but Swellow breaks through the defense. Pikachu attacks Solrock with Iron Tail and Swellow Aerial Ace on Lunatone, defeating both Pokémon. Ash hugs his Pokémon because he won, although absorbs part of Swellow's electricity. Tate and Liza are amazed by those attacks, though Ash confesses he would've almost beaten as well. Tate and Liza give Ash the Mind badge.
