So if Highvolt is the guy in the blurry pic (if you have link to website it was confirmed/said please comment it) then who is Astroblast? He/she is obviously a light element, seeing how a lot of Light characters are based around Space/Electricity.
I know that the photo of High Volt seems a bit faint, but I noticed the gray gears sandwiching the SuperCharger engine pedestal. So I'm gonna say that it is High Volt the Tech SuperCharger.
