Cyborg's can be called Overclocked and during the duration some of his moves are either faster, recover quicker, or add more block stun. Some ideas are: faster dashes/walk speed, his missiles could come out faster to make them more useful to allow for block string mix ups, his grounded fireballs have a faster recovery speed, grapple comes out faster, and maybe his giant fist special adds enough block stun/is plus enough to create block strings.
Then during the regen time maybe he can't use his grapple or something like that.
