Those new monsters were touched upon by Destroyah and Battra, but they were PRIMARILY the Cloverfield monster with scary Decepticon faces.
and in line with that...
"Cloverfield"
The monster came from the Atlantic Ocean, where it was awakened by Tagruato submarines sent down from Chuai Station to investigate. The monster rampages throughout Manhattan, destroying the city in its path. This destruction causes the United States government to sacrifice New York City in an attempt to kill the monster with heavy ordnance in the Hammerdown protocol. Before that, the monster killed Jason Hawkins, crushing him with its tail on the Brooklyn Bridge; its parasites bite Marlena Diamond, causing her to explode from the central cavity; and it bites Hud Platt in half just moments before the Hammerdown protocol.
The whisper after the credits states that the monster is still alive, however, J.J. Abrams states that the military bombing killed the creature. The monster's origins are revealed in Cloverfield/Kishin
The creature, upon arriving to New York City, attempts to eat the Statue of Liberty's head, then throws it into the city when it realizes the head isn't edible. Some say this is a slap at many of the street food vendors in the city (in Manhatten we call them "Road Kill Connoisseurs") and was the first sign of good taste displayed in the Big Apple in decades.
I call it......simply an awesome movie
Thank you J. J. Abrams
