'boom' a huge fist that seemed to emerge from nowhere hit the ground where Raiden was originally located, if not for the special bodysuit he wore that increased his reaction speed and agility he would have been hit by that strong punch that tore a hole in the floor of the street.
The suit was a prototype made by the institute using some of the knowledge zero had sneaked into some of the researchers head, when zero knew Raiden was to be part of the group she had gone back to get the suit from the Institute and remodelled it.
It was covered with fragments of electrically charged metal that were very susceptible to changes in the magnetic field, this made it easier for Raiden to call lightning just by moving any part of his body.
