This is Vortex's EM Wave Change form, a fusion between him and Poly, his partner and Wizard. His design is based on early concept art of Acid Ace and his right arm is based on the new Star Force Mega Man's arm seen in Mega Man Star Force 3.

Do you find something strange EM Wave Change in the 21st century? Well, Poly is from another dimension called "Vespa" whose science and technology is hyper-advanced, so it makes some sense.
