2013's Monster Hunter Frontier G was the first game in the series to feature Dante as a freelancing Rasta who could fight alongside players (for a small payment, of course). Dante's Devil Sword and alpha armour would later re-appear in Monster Hunter World in 2019.

Tanaka Tsuyoshi is the producer of the original Monster Hunter game, and worked on Devil May Cry 2 & 3. The Monster Hunter Frontier G / Devil May Cry cross-over promotion ran from Dec 11-25, 2013. It included Dante and Lady skins, as well as Devil May Cry weapons.
