Dealing with Enemy reversals

Kens 236A is negative on block and the follow up leaves a gap that loses to supers, instead of losing to the supers keep a eye on your opponents bar and don't move your dog, if they go for something you can RC and block safely. Doing this also protects the dog from getting hit in some cases.

Very important to learn the safe jump timing with j.A/j.B with Ken, this gets around a lot of reversals. Also knowing how to 1A4 to block reversals works as well.

Dealing with rolls: Koromaru 5C is really good at punishing rolls, 2C can too but dog positioning matters like if the dog is next to you 2C can work.

Counter Reversals:

All of these reversal excluding Minazuki counter super can be triggered and avoided by using Koromaru to take the hit for you, in other words if you use the dog as a meaty and keep yourself in a position to punish you can consistently punish people for going for this answer.

Minazuki counter super is mind gamey. It triggers and punishes you if the dog hits, there is no avoiding it once it catches you or the dog. But if you know the player intends on going for it. (Usually they get a bit passive and are carefully watching your dog so he can catch it) You can do more...interesting things, you can actually play your frame disadvantage around this, again be careful with your dog use once he gets awakening.

Keep in mind this is just a general way of dealing with reversals.
