Wave the Swallow is one of the members of the Babylon Rogues.  She is the mechanical and technical expert of the group, which she takes after her parent who was a member of the previous generation Babylon Rogues. She is always brimming with self confidence and can be a bit of a trash talker. She usually gives advice that only she can understand, but with all that she is still level-headed and serves as the voice of reason in the group.
