You can mbb/f3 everything except anything that gets lvl 3 properties, it breaks armor, only Superman beats our lvl 3. 1&2 are beatable with that, and we only get 1 hit on all levels if you have anything that hits twice quickly before the move connects.
His grab can be jumped and punished if they try it on every knockdown. Basically you're guessing between a meaty low, grab, or overhead. guess right, and you're out. But the catch is the tick throws, which are very scary. I don't know if your char has a throw immune special, but if he does that will stop cmd grabs and our super on your wakeup.
