The semi-final battle gets under way, pitting Ash against Tobias. The talented Trainer is preceeded by his reputation--he's been defeating his opponents using only his Darkrai. Tobias comes on strong and quick, defeating Ash's Heracross, Torkoal and Gible one after another! But when Ash brings out Sceptile, a spirited skirmish begins, and for the first time during the Sinnoh League, Darkrai is defeated!
Tobias is unfazed by this turn of events. He next brings out Latios, another surprisingly powerful Pokemon. And with one move, Ash's Sceptile is unable to battle.
Ash follows up by bringing out Swellow and a sky battle between Swellow and Latios ensues. Latios proves too powerful for Swellow and Ash is left with one Pokemon, while Tobias still has five!
When Ash turns to Pikachu as his final Pokemon, the action-filled bout gets even more intense and eventually both Latios and Pikachu are rendered unable to battle at the same time. And since Pikachu is Ash's last Pokemon, Tobias is declared the winner! This is the first time Ash has made it to the final four of an event of this magnitude and he has gained the respect of Tobias--who then goes on to triumph in his final battle and is declared the winner of the Sinnoh League!
We leave our heroes as Barry bids them all farewell. Both Ash and Dawn vow to continue pursuing their dreams, while in the face of their determination, Brock finds himself questioning his own plans...
