Wave the Swallow did not originate from fanon, and the information on this page may not be entirely accurate to their canon. You may read more about this subject in the context of their canon on the following wiki(s):
Wave the Swallow is a member of the Babylon Five, and the team's resident mechanic. Like Jet and Storm, Wave is a bully on the race tracks, and is not unknown to cheat; on one occasion, whilst racing in Sand Ruins, Wave placed a smart bomb underneath Sonic's air board. When Sonic was about to cross the finish line, she pressed a button to make the bomb explode, causing Sonic to fall off his board and Jet to win. She is also very jealous of Tails' skills with air boards, and tries to put him down at times.
