The female member of the Blue Planets. She was a professional tennis player prior to joining the team.
Catherine was a famous tennis player prior to joining the Blue Planets. She was one of the first players on the team who warmed up to
Larson. Larson was also attracted to her initially but they would turn out to be good friends and probably the closest teammates in the Blue Planets squad. Being the regular female member of the squad, Catherine was initially shown as one of the team's weakest players but she would show great improvement in her fighting skills as the series against the Satano Blackies progressed. When the Blue Planets won the series against the Blackies, Catherine returned to her pro tennis career but was selected by the Devils team as one of the former Blue Planets' players who would face them.
Catherine played primarily as short stop but also acted as a relief pitcher. Her tennis serve pitch was efficient but she didn't have great endurance and strength to do it in long continuous durations.
