The real cal howard said:
I don't think Goku can find out what abilities Mario has, just how strong he is. Not to mention that this sealing was a one time thing that he did on an opponent he was prepped on. You guy are forgetting that this is Goku. He's not like for example, Zelda, whose entire M.O. revolves around sealing.
Goku can use his Ki Sense to determine Mario's strength. Goku's Info Analysis is what will inform him to what abilities Mario has, and how they function.
Goku's "prep" was the knowledge that he couldn't win the fight by power alone, that he needed to do something else to win the fight.
You are oversimplifying Goku's character just like
ShadowWarrior1999 did if you think that Goku won't seal Mario. If there is a character that Goku can't win by his own merits, he will desperately find another way to win, whether it be fusion, sealing, et cetera. Goku has done this numerous times both within canon and non-canon material. I can list them if you so desire.
And it doesn't matter how often or how many times Goku is willing to use his sealing. Mario lacks the resistance and therefore will be affected by the ability.
Goku might not have a wall of text on his profile, or have hundred of game-breaking abilities at his disposal.
What Goku does have, however, are specific abilities and the right skills that can give him the edge needed to win this fight.
His Ki sensing and Info Analysis will lead to Goku realizing that he can't beat Mario with his own strength and that being touched by such a being's attacks would mean his certain doom, so therefore he will attempt to dodge Mario's attacks.
His greater mobility (true flight, teleportation, et cetera) and Mario's limited range due to his stature and the fact that all of Mario's abilities are projectiles that can, in fact, be dodged will lead to Goku being able to dodge Mario's attacks.
Goku's greater fighting skill, martial art's genius, and character mentality will lead to him realizing that the only way to beat Mario is to seal him like he did Omega.
Mario's lack of sealing resistance means he will be affected by Goku's ability.
To reiterate my vote, Goku wins this 8-9/10 times.
