Skeetera



Zilla battled Skeetera in Miami and it was then transported to Monster Island. S.C.A.L.E. then released all the monsters (King Cobra,Giant Bat, and Crustaceous Rex) but they were eventually rounded back up by H.E.A.T., Zilla, and the military. Skeetra was the last monster to be stopped, and was killed in the process.

Toho later used a similar idea for Megaguirus.
