Tula was the culprit of a crime that almost ruined a photo shoot of the BW Agency. After Black found that out, he battled and defeated Tula while capturing it. It was revealed that Tula once belonged to another trainer until Ghetsis's speech swayed him to release it.
Tula was used by Black in his third Gym battle against Burgh of the Castelia Gym. He was sent out to battle Leavanny when switched out. The match ended in a double K.O. after Tula poisoned Leavanny.
