Transmorphers (2009)

The Earth, largely concerned with minor matters, fails to notice the arrival of the Transmorphers, a race of robots that are piloted by extraterrestrial beings. The machines invoke a cybernetic revolt, using their advanced technology to destroy the opposition posed by the world armies and thus quickly seize control of the Earth, forcing the remainder of the human race underground. Despite being the first original sequel to a mockbuster, it is not the very first mockbuster sequel, which was War of the Worlds 2: The Next Wave (2005), an extension of Asylum’s adaptation of The War of the Worlds by H.G. Wells.
