When Dr. Foster announced the first match-up, he looked around for this Jacen and gave a nod towards his first opponent. Of course as luck would have it, he would be in the first match. Jacen's apperance did sort of looked familiar. Maybe he ran into him the few times he had been at the bar. He wasn't familiar with the Braavos region, he himself came from Mauville in Hoenn. Though just looking at guy, he could tell this would be a tough match and as they got to the arena his choice of pokemon showed that.
His opponent had an Accelgor, a bug type who was know for its speed. His own choice would have to be important. While Bronsor had ancient power to combat the bug type, it was neutral to bug whereas Theta resisted it though didn't have super effective attacks. But it's electric attacks would mess with the pokemon's speed which would be useful to be able to defeat it. "Ok then, Theta let's go."
The magnet pokemon gave a chirp in reply and took its place on the battlefield. "Theta, start off with a Metal Sound and then follow up with Flash Cannon. Then use Thunder Wave." As the steel type bobed a nod, Alex had a flashback to his first battle here at Fizzy Bubbles. It was against a trainer named Charm and even with a type disadvantage, it was a close fight. The same stratagy applied here, lower its defences, attack it, paralize it. That would be a perminate stratagy for his starter.
