The Japanese official Pokémon site updated with information on this event. Genesect's Techno Blast attack changes type depending on the item that Genesect is holding. In total, it can have four different types, which are:

• Fire Type (when Genesect is holding the Burn Drive)
  
  
  


• Electric Type (when Genesect is holding the Shock Drive)
  
  
  


• Water Type (when Genesect is holding the Douse Drive)
  
  
  


• Ice Type (when Genesect is holding the Chill Drive)
  
  
  

The special Drives that are needed to change Techno Blast's type can be obtained when players take Genesect to the P2 Lab. There, they will be challenged to a battle by a Team Plasma researcher and if they win, the researcher will give them two out of the four Drives. Pokémon Black 2 players will get the Burn and Shock Drives, while Pokémon White 2 players will get the Douse and Chill Drives.
