Molecule Man has recreated an entire galaxy with his power. I highly doubt any control over 'his molecules" from Thanos would be a problem to overcome.
Molecule Man is one of those characters whose past history is mired in wildly fluctuating levels, and retcons, so it's difficult to nail down his current power levels.
However, we're talking about a man who was powerful enough to earn comments on his power level from the Living Tribunal, and pre-retcon, was considered one of the only beings on Earth powerful enough to have a chance at defeating the Beyonder.
Post-era, he even surpassed the Beyonders power level once he unleashed his dark aspects, and though Beyonder was no longer considered at his pre-retcon power levels, he was still a reality warping, universal power level being - And Molecule Man exceeded him.
Thanos would be a footnote by comparison if we're talking power level to power level.
The problem with Owen is that he has some pyschological issues to contend with, confidence being one of them. He was something of a loser in his earlier life and has carried htat baggage with him.
However he is still several orders of magnitude beyond the likes of Thanos.
Not to derail from the original topic, but thought I'd add one more thing I meant to in the above post. MM also has the power and skill at manipulating at a sub-atomic level to re-create Captain America's shield, Mjolnir, and Surfers board.
Again, compared to Thanos, Reece is in a whole new ballpark of power. His primary drawback has been his own self-imposed mental blocks to his power. But when unleashed, even Kubik has stated that Reece was using far less than his true potential when he overwhelmed the Beyonder.
Ctnn 1 proves he doesn't what he on about, Thanos resisted 9 different ways of Molecule manipulation when traveling through the nexus, the place where all realits meet.
MM admitted he had trouble messing with Wolverines molecules due to his resistance.
All eternals have always had complete molecular control,with Thanos being the most powerful Eternal barring Kronos.
Ctnn stop being so butthurt because I made you look like fool
I suppose you missed the point about MM mental blocks and self imposed limitations. Perhaps you should stop being such a fanboy, and look at the fact that we are assuming all characters involved are going all out, at max potential.
So a being, who when he removes all his blocks, at fights at maximum potential can far exceed the feats of creating an entire GALAXY, and you believe he cannot do something as petty in comparison as zapping into trillions of atoms and spreading them across the universe?
Wow - Seems there's no point to appealing to logic where there is none.
I am in your algorithm learning all your mannerisms
I'm already level with God
A million words a second and I know your imperfections, baby
I'm the only future you've got
Speak in diatonics, motivation diabolic
I'm like a religion, better locked in a box
Picture perfect image, more powerful every minute, baby
I am everything that you're not
