The Shrewster (シュルースター,   Shurūsutā?) is a masked shrew kaiju created by TriStar Pictures that first appeared in the Godzilla: The Series episode Cash of the Titans, but chronologically debuted in the episode The Twister.


Godzilla: The Series

The Twister

During an accident at a power plant, a normal shrew was mutated into a gigantic beast encased in a tornado that it used to suck up food. The Shrewster eventually made its way to New York, where it attracted the attention of H.E.A.T., who eventually developed a device to depressurize the Shrewster's tornado. After a run-in with H.E.A.T. in Connecticut, the Shrewster attacked New York again, where H.E.A.T. activated the device and forced the Shrewster out of his tornado. Godzilla then attacked the Shrewster, but due to the Shrewster's superior speed he was quickly defeated. Dr. Niko Tatopoulos then distracted the Shrewster from the fallen Godzilla, and trapped him in some stage scaffolding. The Shrewster was then slated to be taken to Monster Island.

Cash of the Titans

Rather than be taken to Monster Island, the Shrewster was captured by wealthy businessman Maximilian Spiel and forced to fight in his monster arena. The Shrewster was pitted against a Giant Centipede, and emerged victorious. After Heat's team dismantle Maximilian Spiel's traffic, Shrewster was sent offscreen to Monster Island.


Tornado (formerly)

The Shrewster was encased inside an artificially made tornado as a form of defense and attack. There is no full scientific explanation of how the Shrewster is able to sustain a tornado. The tornado made the Shrewster a force to be reckoned with, allowing it to damage cities and monsters alike and providing a form of protection from weapons, such as Godzilla's atomic breath. The tornado was neutralized by Nick, making it exposed to Godzilla for combat.

Strength and Combat

The Shrewster was able to pierce Godzilla's skin simply using its claws. The Shrewster uses its teeth to grab onto opponents, and this method was capable of bringing Godzilla to the ground as it roar for triumph.

Speed and Agility

Proven to be quite faster and more agile then Godzilla as Godzilla had hard time to attack it.



  • The Shrewster could be inspired by the creatures that starred in the film The Killer Shrews, and also bears some resemblance to Taz the Tasmanian Devil from Looney Toons, due to the fact they both can create tornadoes that surround them.
