This is kind of a mismatch, as detailed above. Probably not appropriate to vote/debate it as such.
Incidentally, about Protagonist's speed....
Speed: Normal Human with
Massively Hypersonic+ to
Immeasurable reactions (Can consistently react to his Digimon and other Digimon attacks throughout the game)
Is he able to travel as fast as he can react? Can he move across the battlefield at MHS+ speeds?
According to this calc, Ash can lift
4164.09 kg:

If Protagonist can only move about at Normal Human speeds, if Ash could just find a big enough sheet of metal (Or light enough stone), he could squash Protagonist; Normal Human movement speed is 5 to 7.7 meters per second.
So if Ash could just find something roughly 5 to 7.7 meters wide and long to swing from overhead onto Protagonist, he'd be able to splatter him like a bug under a flyswatter. (Minus the handle of the flyswatter.) Assuming the swing takes only about 1 second, Normal Human wouldn't let Protagonist move far enough to get out of the way.
Problem is, huge sheets of swingable objects aren't exactly common to find, & I'm not sure it's not really in-character for Ash to fight like that.
(Also, I'm not even sure something that big & thin would be sturdy enough to survive the swing, nor if something that big would actually BE withing Ash's Lifting abilities.)
And also that the tier difference means Protagonist probably can't hurt Ash anyway, so mismatch, lol.
