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. As the title suggests, the player takes the role of a Hunter in a fantasy environment and completes quests by hunting out specific kinds of monsters to kill or capture.

Mega Man content
In Monster Hunter 4 Ultimate (Monster Hunter 4G in Japan), Mega Man's armor appears as the Mega Man Palico Armor set (ロックマンネコシリーズ, Rockman Neko Series in Japan) for Felyne comrades (Palicoes), and the Palico Weapon named Rushing Hammer (ラッシュハンマー, Rush Hammer) based on Rush. They are created with E-Tanks, which are only obtained by completing the Event Quest Protector of Peace.

The Mega Man armor set, renamed as Rocknyan (ロックニャン) in Japan, and the Rushing Hammer return in Monster Hunter Generations, with the added feature of the Palico using the color of several Special Weapons in his actions, such as Super Arm, Leaf Shield, Top Spin, Dust Crusher, Ring Boomerang, Gravity Hold, and Flame Blast. When he eats, he holds an E Tank instead of food. The Mega Man gear is created with Ceratanium, which is obtained in the Event Quest Mega Man: Yellow Devil (ロックマン・黄色い悪魔).

In Monster Hunter: World, an 8-bit Mega Man armor was available to players for a short time. Just like in Monster Hunter Generations, when he consumes a Potion, he uses an E Tank instead. The armor set can be obtained in the Event Quest "A Rush of Blood".

In Monster Hunter Frontier Z, a Mega Man costume is available for Hunters.

In Monster Hunter Explore, Mega Man X content appeared during a January 2019 event, including X and Zero armors and weapons.

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 plans to send it to attack Sigma.
