Dr. Light was intrigued by this technology and, shortly after his encounter with the Ikaruga, integrated the technology into his own technological marvel: Megaman.

Megaman fought two seperate battles with this 'polarity shield.' The first was with a new enemy which, as a good test to the shield, fired completely opposite weapon polarity than what Megaman was used to.

Megaman's second battle was with Bass, who also had obtained a polarity switching chield of his own. When Megaman defeated him, Bass hinted that there was more to come. A short while later a lab was found which appeared to be experimenting with the technology. Could this be what Bass was referring to?"
