Before the regular Ash stumbled upon the Mirror World, Mirror Ash had a battle with Mirror Serena, which he lost. After this, Mirror Serena bragged about it and called Mirror Ash a crybaby. This caused Mirror Ash to run off and decide to travel by himself. He ran towards Reflection Cave but lost his. While looking for him, Mirror Ash came across a mirror, in which he saw Pikachu. He managed to pull through the mirror and grab Pikachu, unaware that this was the from the regular world, which he just pulled from the regular Ash's shoulder. Though initially happy he had found Pikachu, he later realized this wasn't his Pikachu.

Later, Mirror Ash found his way back to his friends and witnessed a battle from behind a tree between Mirror Serena and Ash from the regular world, who had followed Mirror Ash to get his Pikachu back. After the battle, he showed himself. Mirror Ash then told what happened to the group after he had left them. Mirror Ash had still not found his own Pikachu, so the group decided to look for him with help of Mirror Clemont's magic. They ended up at a dead end however.

To get both Pikachu back, the group battled them, with regular Ash and Mirror Ash teaming up and both using their. Team Rocket ended up defeating them, however, causing Mirror Ash to give up and cry. A speech from the regular Ash convinced him to continue again. Mirror Clemont used this moment to steal the cages with the Pikachu and Mirror Serena managed to free them with her. Both Ashes then used their freed Pikachu to blast Team Rocket off. Mirror Ash now decided to still continue traveling with his friends instead of traveling alone.

Afterwards the group enjoyed the sunset. However, this caused Mirror Clemont to remember that anyone not from the Mirror World would be trapped inside the Mirror World forever once the sun had set. They hurried to Reflection Cave to ensure the regular Ash would go back to his own world in time. Although they found the mirror through which the regular Ash had come, the portal wasn't there. Then Mirror Ash remembered what caused the portal to appear when he grabbed the regular Ash's Pikachu. Eventually, the portal appeared as the regular Ash wished strongly to return to his own world. The regular Ash managed to go back, and Mirror Ash and his friends said their goodbyes as the portals closed again.
