The Version 2.0.0 update adds Marx to the game's cast of Dream Friends; accompanying this is a new fight against him during the credits for Heroes in Another Dimension. While this fight has no bearing on the player's progress, he is actually coded as a full-fledged boss, complete with a health bar and battle music. In normal gameplay, the song, "Vs. Marx — Star Allies Dream Ver.", is only heard when fighting Morpho Knight as Marx. These features can only be seen in action by hacking the game; since Marx has no "ending" programmed for his fight (as it normally occurs during the credits), beating him under these conditions softlocks the game.
