Isaiah is a character appearing in Pokémon: Advanced Battle.
Season 8: Advanced Battle
Isaiah saw the heroes with a Spoink, who lost its pearl. Isaiah approached them and claimed some Clamperl he studied may help them out. After introducing himself, Isaiah took the heroes to his lab, where they saw Clamperl, but without any pearls. The heroes saw a blue pearl, which Isaiah studied and wanted to know what is it that gives the pearl a blue color. Just as the group went out to find Clamperl, an alarm rang and they soon found out Spoink took the blue pearl, which made Isaiah sad, since he never got to start his research on it. Once they found Spoink, they saw it had a pink pearl and were told by two children Spoink swapped the pearls. Once they found Clamperl with the blue pearl, Team Rocket appeared and snatched Clamperl. Fortunately, the group tracked Team Rocket down and defeated it. Clamperl gave the blue pearl and allowed Spoink to keep its pink pearl, which made Isaiah glad everyone was satisfied.
