This sounds crazy but there are two collaborations between Monster Hunter 4 Ultimate and the two famous franchises, Sonic and Taiko, being available in all the versions of the games.
Taiko will be an instrument type weapon that can be used byย your character and Sonic will just beย a suit for the character’s companion allowing it to wear theย sword Caliburn (fromย Sonic and the Black Knight).
