The Needletron is a created by Marcus when he infiltrates the school blood drive & uses the "pierce" Metavirus to infect a syringe & a trolley of medical equipment. It is used to infect humans with a virus to turn them into machines. Its data is uploaded onto a Viratron Beta Upgrade to create the Needletron Upgrade. It was deleted when Bree & Chase hit it with two charged slashes from their Binocular Sabers.
