Jack began flying to Sunyshore City to get his eighth and final badge. After he healed his Pokemon he went straight to the gym.
"So, you're finally here," a mysterious man in the dark said.
"Who are you?" Jack asked.
The gym's light's turned on and Jack smiled.
"I'm Volkner, this city's gym leader, you must be Jack. I've heard how you easily handled the other gym leaders, this gym won't be the same," Volkner said.
"Oh, I wouldn't be so sure about that, you see, most of your Pokemon won't even be a challenge," Jack responded.
"We'll see about that, go Jolteon!" Volkner called.
"You're Jolteon is already fainted, in my eyes, go Aura! Use Earthquake!" Jack commanded.
Jack's Lucario used his power to shake the ground and cause an Earthquake powerful enough to one hit Volkner's Jolteon.
"Jolteon, return, go Raichu! Use Charge Beam!" Volkner shouted.
Jolteon was replaced with Raichu which unleashed a powerful line of electricity at Aura. However, Aura is strong against electric type attacks and took minimal damage. "Finish this with another earthquake," Jack said calmly. The same way Jolteon fainted, was the way Raichu fainted.
Jack said,"Listen, you're Pokemon will faint to the same cause and you can't stop it, look I'll even use another Pokemon. Just make this faint entertaining." Volkner grunted and yelled,"I will not let my Pokemon succumb to the same fate by one single move, go Luxray!" Jack smiled and replied,"Thanks, alright I already know you're Luxray is faster and will use Fire Fang so let's not take Super Effective hits and instead, return Aura. Go Inferno, use Dig." Inferno barked and went underground. Luxray kept his eyes at the ground the entire time. Inferno escaped from the ground under Luxray and attacked. "Luxray look out!" But Luxray was already fainted. "Return. Alright this is my last Pokemon and my strongest, go Electivire!"
"If you're using an Electivire, then I will, too. Go Voltz!" Mike shouted. "Thunderbolt!" both trainers exclaimed simultaneously. Both Pokemon responded in the same actions and afterwards fell to the ground. Now it was a matter of who would get back up. Slowly, the two Pokemon got up at the same time, but Volkner's Electivire fell back down. Volkner stared at his Electivire in shock. "It can't be." Then, he looked up. "But the rules are rules. Here is your eighth and final badge. You've earned it, even if you got it as easily as your other badges. But Jack, let me tell you something. You are more than stronger than the current Champion. When they fought against me the lost all but one Pokemon. But you easily defeated all of my Pokemon, I think you may be the strongest trainer of all of Sinnoh," Volkner admitted. Jack accepted the badge and replied,"Thank you for the kind words, I promise I'll try to prove your words as facts." He turned away to go to the exit and his next stop, the Pokemon League. Jack couldn't hear it but as he was walking towards the exit Volkner said,"You already have Jack. You already have."
