Basic Action Super Heroes!

If a character is hit by a damaging Mighty Success, is it a valid tactic to Yield Advantage to a Mighty Success (thus making the attack an ordinary success) and then attempt a Parry?

I would say yes; but remember the Parry Roll has to exceed the attack roll, so that is a real gamble.

Yeah - I realise it's a desperate idea but, heck, it might just work
