As Kyogre continues to press forward, Team Aqua clash furiously with Wattson, Winona, and Flannery. Amber has just arrived and has his Pelipper use Stockpile and then Spit Up to strike Wattson's Manectric. The battle is now three-on-three, with Flannery and Shelly, Winona and Matt, and Wattson and Amber going head-to-head.
Amber taunts Wattson, saying their fighting is giving Kyogre time to advance, but Wattson retorts that his own Electric-type Pokémon have the advantage in this fight. Wattson's Manectric takes out Amber's Pelipper with one hit, leaving him with no remaining Pokémon after his remaining team had been left behind at the Seafloor Cavern. Shelly decides to lend Amber her Nincada, which he happily accepts. Even with the Pokémon he borrowed, Amber is still easily defeated by Wattson's Manectric, confusing the Gym Leader.
Amber reveals that he picked Nincada due to the fact that it would evolve. Nincada quickly evolves into its next stage, Ninjask, and goes on the attack. With Ninjask's Ability, Speed Boost, it manages to easily out-speed Wattson's Manectric. Wattson manages to counter Ninjask's speed by ordering a Double Team, allowing Manectric to gain the speed to hit its opponent.
With its opponent pinned to the ground, Manectric uses a powerful Thunder attack, which defeats its opponent at the cost of knocking itself out. Due to Wattson still having more Pokémon able to battle, he confidently names himself as the victor. Wattson's victory is short lived, as he is quickly knocked out by a Shedinja. Amber reveals that Wattson made a careless mistake of not knowing that when Nincada evolves, it leaves behind a shell that becomes a Shedinja. As Wattson falls into the water, Amber states that he lost the battle because he did not know about Nincada's abilities.
Flannery tries to rush in to help Wattson, but is stopped by Shelly, who states that she is her opponent. As Wattson falls off the island, Flannery cries out in horror as he falls into the water.
