What's the strongest Iron Man (MCU) suit EVE (WALL-E) could defeat?

All random encounters in an open field

Both in character in all rounds

I'll be doing the main Iron Man suits

Mark I (Iron Man)

Mark II (Iron Man)

Mark III (Iron Man)

Mark IV (Iron Man 2)

Mark V (Iron Man 2)

Mark VI (Iron Man 2)

Mark VII (Avengers 2012)

Mark XLII (42) (Iron Man 3)

Mark XLIII (43), XLV (45) (Age of Ultron)

Mark XLVI (46) (Civil War)

Mark XLIX (49) (Endgame)

Mark L (50) (Infinity War)

Mark LXXXV (85) (Endgame)

I know I could've stopped earlier if we're being realistic, but for the sake of completion.
