Like, nothing outright contradicts tier 4 Mario going by final bosses that he beats the snot out of and the consistent enough feats of said bosses that he'd power scale to due to them being story based feats stuff like sustaining and collapsing starry sky realms ex: Luigi fighting King Boo in Luigi's Mansion: Dark Moon and Wario fighting Black Jewel in Wario World.
In my opinion, for tier 3-A Mario and above? Story wise it creates a really long list of inconsistencies. I can go through this list lol
- Mario 2, pretty sure its just all just in Mario's dream in the original. He's just lying in bed lol. Not really sure if we count the doki doki version XD
- SMG, Mario and Peach being protected by Rosalina's shield from a blast that threatened the fabric of the universe; something that would create an inconsistency if we want to scale them directly to this showing of the Grand Stars' feat in the first place. Also, Mario being unable to break Rosalina's shield with his stomp attack, same attack that could tank the above blast if he's equal to or above that tier.
- Super Paper Mario, they were basically killed by Jaydes in the alternate ending, when the Void was scaring her at its current state. Bleck after obtaining the power to destroy a universe called Mario a "weakling" after knocking him out and after Mario stomped and failed to break his barrier.
- Mario Party 6? - never played it rofl
And in any sense we treat everything but Super Paper Mario as under the same universe but they are canon to each other due to dev statements so it would mean trying to be consistent across those games.
Although powerscaling Paper Mario to 3-D Mario is ok if you wanna use Paper Jam, but even so the shared universe should be different regarding the paper one and the 3-d one
