The Maverick was designed by Jean-Sanque Gulio, the most esteemed Rune Caster in the ancient kingdom of Kounat during the First Demon War. When Kounat came to an untimely end at the hands of a mysterious explosion, the secrets of the Maverick and the secrets of building them were lost forever. However, it is believed by scholars that the rifles used today by the dwarves of Archimedia are based on the ancient design of the Maverick.
- The Maverick's design is based on the 2005 Nerf blaster, Maverick REV-6.
- In Grand Chase Dimensional Chaser, the Maverick has neither appeared nor used by Mari as one of her weapons.
