Subway Boss Ingo is one of the leaders of the Battle Subway in Black, White, Black 2, and White 2, along with Emmet. Ingo is referred to as "big brother" by Emmet in the Japanese version of the anime, indicating that he is the older twin. Ingo and his brother Emmet are markedly similar. They are both composed and precise in manner, important attributes to his role as one of the Subway Bosses. This also extends into Ingo's battle strategy. He often takes the lead, creating an opening for Emmet to attack.
