The Frankystein Mark II, known as Frankystein 2 in Japan, is a boss encountered in EarthBound. It is a robot invented by Frank Fly, the leader of the Sharks, for unknown purposes. It resembles a tank with a robotic-looking torso, arms, and head.


After Ness beats Frank, Frank brings out what he calls his "trump card": the Frankystein Mark II, which then attacks. However, Ness defeats the robot, prompting Frank to give in and reform himself.

His in-battle theme is shared with Captain Strong, the Boogey Tent, and the Department Store Spook. It is one of the few mechanical enemies that does not use Battle Against A Machine as its battle theme. Its name is a reference to Frankenstein's monster.


Frankystein Mark II will attack roughly every other turn; it relies on punches that deal low damage, and will occasionally tear into Ness for significant damage.
