The Chill Drive (Japanese: フリーズカセットFreeze Cassette) is a type of held item introduced in Generation V. It is one of the Drives, which are associated with Genesect. It corresponds to the Ice type.
Changes a Genesect holding this item to its Chill Drive form. Item-manipulating effects (such as Trick and Fling) cannot give Genesect a Drive or remove a Drive from Genesect.
The Chill Drive, along with the other drives, appeared in Genesect and the Legend Awakened, attached to the members of the Genesect Army, with the exception of the Red Genesect. While in the movie it was used with the same purpose of changing the type of Techno Blast, it was also the key item to tell each Genesect apart.
