Ceti Alpha Seven

Ceti Alpha Seven - a planet of murky jungles and swamps - was the site of a Decepticon facility under the command of Deathsaurus. Its function was to unlock the then-thought-lost cloning ability of the Insecticons. Using Dirge and Buzzclaw as bases, Deathsaurus was indeed able to produce a horde of Virulent Clones, but he ultimately destroyed the facility in an attempt to kill a captured team of Autobots.
