Bayonetta sports a new hairstyle in the game. She transitions from her beehive style to a much shorter style. When asked about this, the creators said that Bayonetta is a character that likes to change her style from time to time and likes different appearances.
The game's Wii U exclusivity came to be as a result of Sega (the publisher of the first Bayonetta title) declining/refusing to publish the sequel and Nintendo stepping in to fill that role.
Along with their hairstyles, Bayonetta and Jeanne's eyewear has changed. Bayonetta's original black glasses with red butterfly wings are replaced by more intricate glasses, with large blue flowers in both sides and spiraling temples. Jeanne's signature red winged glasses are put to the side by a pair of cat themed motorcycle goggles. The original glasses can be seen in different costumes, however.
