Mitch 1M keeps enhanced strength and flight as his default abilities:

And mind you, that "enhanced strength" already puts base Mitch at a level where he can casually palm a punch from Superman, and then rock him with a punch of his own:

Only thing I would note is that it does take *some* degree of time for Mitch to shuffle through powers if the above defaults aren't enough. He has to activate the Resurrector device, 'die', then resurrect with a new power of his choosing.
That said, the above process doesn't take long at all. Mitch was able to do this in the time it took Superman to blitz him from a short distance away:

And again in the middle of a sentence:

Team's best chance is to disable the Resurrector device at the onset, imo. Granted, Mitch can still 'die'/power-shuffle/resurrect very rapidly the old fashioned way:

...But that takes [slightly] more time and is less consistent, at least. /shrug
