I'm conflicted on this. On one hand energy absorption is indeed Michael's entire thing. On the other hand, I still think he'd really struggle with fighting Met, even if his powers hard counter Met's.
The major issue he'd come across is control. The control over their Monster Energy that living targets have is an issue for Michael. If a living monster or superhuman is equivalent to or weaker than him in power he can forcefully rip energy from them, but the energy is a mere trickle. Met is most certainly not weaker than Michael. And even if Greater/Apostle spawn shenanigans lets him manage to pull Monster Energy from Met despite him being a Level 3, it's been firmly established that Met is really good at manipulating his own power. Good enough that he learned to manipulate his electricity at range when he charges something. Whatever he'd get would be scraps.
I can't see him winning, but whether he can put up a decent fight is up for debate. There are some interesting questions that make me think he might have a chance. While Michael struggles with internal energy sources, he notably doesn't seem to have any issues with external energy sources that have been thrown at him, like ranged attacks. This is to the extent he could eat attacks from a C rank at Level 1 despite them being Level 2 equivalents. Since Level 2 is where the shenanigans really start for Greater/Apostle spawns, I still think he'd tank any ranged attacks Met tries outside of the highest output ones like the Lightning Dragon. While Met would no doubt figure this out damn near immediately, being an experienced combatant from Michael's family, I do question if the lightning he uses as a passive defence counts as easy to absorb external energy. Furthermore, does Met's electricity count as natural energy, supernatural energy or both? Depending on which, the fight could tilt surprisingly closer to equal Michael and Alice's favour.
Michael has some of the nastiest powers in the entire game with bursts of radiation potent enough to not only hurt a Level 3 MC but also stall their extreme regenerative abilities, a large pre-existing energy stockpile going into the fight, enough skill that he was dodging lightning at close range back when he was a mere human and is backed up by someone who can theoretically hold their own for a while and has abnormally high attack potency. Instead of being a one-sided beatdown, this might just turn into a high-stakes uphill battle for Michael and Alice. They're still totally screwed if they let Met get even one good hit as he could probably fold them like laundry with sheer physical strength alone, and something's going to have to save them or give them a chance to run. But unlike normal Level 2s both are abnormally strong and Michael is near definitely capable of wounding Met.
