Charlotte Bony is one of the former members of the American Colony and was part of an elite unit prior to the Petrification. She's overzealous and appears to idolize Stanley Snyder. She is currently a member of the Kingdom of Science. Charlotte is a dedicated and extremely loyal person, especially when it comes to Stanley. She usually seems serious and plays by the rules, but isn't afraid to banter during the dogfight with Ryusui. She is quite confident in her abilities, believing the enemy was foolish to challenge her. However, it is shown that even she can become frustrated as she was in disbelief by the enemy overcoming her in their aerial battle. However, unlike some of her comrades, Charlotte isn't completely unsympathetic. After she is saved by Suika, Charlotte begins to hesitate when accepting the order to to kill all on sight, due to the enemy showing her mercy.
