S16·E25 What Lies Beyond Truth and Ideals!

As the revived Reshiram quickly falls under Ghetsis' control, Ash and friends try to develop a strategy to stop Team Plasma. Looker convinces Team Rocket to help in the fight against the villains, while Ash and Pikachu aim to destroy the controlling machine, and N hopes to pacify the enraged Reshiram before it destroys the world in a righteous fury - akin to when it burned down Team Plasma's castle in the past.
