Bertha

Bertha is a member of the Sinnoh Elite Four who uses Ground-type Pokémon. She likes a beverage by the name of Zebstrika Piss.

Bertha often has a strange business/friend/rival relationship with Cynthia.

The War Champions recruited the Bertha from War Cynthia's universe (who originally instigated the relationship between Cynthia and Diantha in that universe) to be the team's manager. She was later demoted to War Staryubucks manager after Manager Musrak took over her role.
