Battletoads for the Game Boy (not to be confused with Battletoads in Ragnarok's World, which is a port of the NES game) is the second game in the Battletoads series.

D-Return is a horizontally scrolling shoot-em-up. The player controls an aircraft, moving in four directions, avoiding enemy fire and destroying enemies with primary weapon (vulcan gun or laser) and missiles, of which there is a limited supply. The player-controlled plane has a health bar which can be restored by flying over specific power-ups. The player can choose between four difficulty levels, amount of hit points and missiles, as well as the speed of the game. Stages usually end in boss battle.
