[MCU] If Stark used all his battle data from fighting Thanos to create a Thanosbuster suit, what do you think that armor would be like?

If Earthman Stark could singlehandedly build a suit that could go toe to toe with the Infinity Stones, I'd have to think Thanos was pulling his punches. How do you tech around the ability to stop time? Or the ability to manipulate the very fabric of reality.

Is there any suit Tony could build that Thanos couldn't immediately overcome by turning the power off? Turning into a fine Gouda? Mind wiping Tony so he thinks he's a set of mahogany drawers?

He phoned it in during the final assault on the Mind Stone, being about as unimaginative as one could get given the power at his command and yet barring a moment of shock/respect at Cap holding him up, he didn't even break a sweat.

If Thanos is anything more than comatose, you can't build around that. Tony can't win, Thanos would have to lose... pretty much intentionally.
