How do you counter Kenji & Mico? (+ how do you dodge Kenji's super?)

Ever since I started going against Kenji & Mico I barely win any 1v1s with them like what do you do if you're not a tank!! Mico can get close easily and when he does it's just over. Kenji has his stupid health regeneration thing I don't even know how it works but there's nothing I can do to kill the guy, and how do you even dodge his super? Everytime he supers I feel like it's fucking guaranteed to hit I almost never get out of it without taking damage
