Monster Hunter

The Monster Hunter (モンスターハンター) franchise is a series of video games by Capcom that started with the game Monster Hunter for PlayStation 2 in 2004.

Other media
Monster Hunter is one of the franchises featured in the Archie Comics crossover Worlds Unite. The X-Hunters are preparing to set a Unity Engine in the Ancestral Steppe, but X and Sticks appear and the trio prepares to fight, kicking two nearby Felynes (a valiant Palico using the Mega Man armor set and a normal Felyne using the Sonic armor) out of their way. Suddenly, a Gore Magala appears and easily destroys the X-Hunters. X prepares to face the elder dragon to protect the Felynes, but Sticks tries to talk with it and somehow calms the beast down, and sends it to attack Sigma.
