Mystery Tank

Mystery Tank, known as Mystery Can (ミステリー缶) in Japan, M Tank (M缶) for short, is a Tank item from the Mega Man series. Like the Super Tank, the M Tank recovers the energy from Mega Man's health and all Special Weapons, but it also contains an additional effect: If the M Tank is used when the health and all weapons are with full energy, it will turn all weak enemies on screen into 1UPs, or give the player one extra life if no weak enemies are nearby. Also like the Super Tank, only one can be carried at a time.
