Clover

Clover is the production name given to the giant, fictional monster that appears in the 2008 film Cloverfield. The creature was originally conceived by producer J. J. Abrams and was designed by artist Neville Page. In the film, the monster is never named; the name "Cloverfield" is only given to the US Department of Defense case file of the incidents depicted in the movie. The Department of Defense names the creature "LSA" for Large-Scale Aggressor in the movie's Blu-ray special feature called "Cloverfield Special Investigation Mode". The name Clover was the nickname affectionately given to the monster among the production staff.
