Bellatrix Tyler, more commonly referred to as "Belle", is a member of Team Rocket and is the partner to her cousin Chloe Tyler.
Belle is a semi-tall young woman with long pink hair, that is normally kept in a high ponytail and deep gray eyes. Her standard outfit is the black Team Rocket Uniform.
Unlike her cousin, Bellatrix shows no emotion most of the time, and just lets Chloe do the talking. No one is able to tell what Belle is thinking due to her keeping her emotions to herself. The only time she ever does display emotion is when her Pokémon are involved.
Prior to the series
