The Ultra Nanotech was the greatest Nanotech supplement drink that Ratchet could buy from a special dispenser on planet Orxon. It cost 30,000 bolts and was three times more potent than the Premium Nanotech supplement, increasing the Lombax's maximum capacity of Nanotech by three. It could only be purchased if Ratchet first bought the Premium Nanotech supplement, and when combined effectively doubled his health, meaning he could take 4 more hits before being defeated.
