While doing a fight club I try to use facts that I know when comparing two fictional figures. I also use a set amount of canon when it comes to the fighting potential and abilities of the two brawlers, in this case I'm using Jim Carrey's "The Mask" or Big Head for the comic fans meaning only things Stanley Ipkiss did in the Mask movie is canon in this fight, and the more violent version in the comics won't be used here. As for the Zohan, the only known source of this comedic character is Adam Sandler's movie, "Don't Mess with the Zohan" so I'll be using things the Zohan did in that movie as reference, if there is another media the Zohan is in, let me know but it won't change the out come of the fight either way. Also the person who wins the most categories does not win the fight, this is just a look at advantages and disadvantages each character has. On with the fight.
The Mask vs. The Zohan
WARNING possible spoilers and chaos WARNING
The Zohan as crazy as he is actually has a style of fighting. I'm not sure what the term is for his style, but he has one unlike the Mask who has cartoon antics and mayhem. Zohan can do the foot uppercut, an absurdly long flying kick, and can do a chant that breaks the sound barrier and causes more crazy things to happen. The only reason that the Zohan doesn't win this category by a landslide is that if Stanley so desired it, he could become a black belt cartoon style while the Mask. Given the Mask would do more gags while trying the fighting style, so Zohan would still be better but the Mask could catch up.
Zohan can raise goats, cut hair, and do nearly anything including making a weapon out of any object nearby, similarly to the Mask. Zohan's skills are less cartoon and more practical even in the heat of battle, which again the Mask is close behind on this category as the Mask can make a simple car into a death trap if he do desired, though the Zohan does have far more experience in the art of battle then the Mask does.
Yes the Zohan has that earth shattering chant, however the Mask has a little horn that can do the same exact thing but more focused, and he can do it quicker when need be. The Mask can pull anything out of his pockets including a hammer, guns, car parts, and probably more but those are examples in the movie. If the Mask wants to, he can also shapeshift and be anything and can literally force people against their will to dance, and he can do this to so many people that he could produce his own stage show to distract enemies when need be. Zohan has more potential in actual fighting, but the Mask has super powers that warp reality while Zohan only has super strength and speed. The Mask can also be riddled with bullets and live while the Zohan has to catch them.
The Mask can literally pull anything from his pockets as well as make anything nearby a weapon, while Zohan can make things nearby a weapon it isn't to the extent the Mask can make things into a weapon.
The Zohan has no trouble killing people while Stanley Ipkiss as the Mask... from the movie... killed no one. His inner desire isn't known for being a killer unlike his comic book counterpart Big Head. Zohan would easily kill the Mask long before the Mask would kill the Zohan, so expect a bit more ferocity from the Zohan himself, though in the long run Zohan isn't a bad guy and often doesn't kill if he doesn't feel a need to do so either so he isn't too far ahead here.
The Mask unfortunately is near indestructible, and is far more the invulnerable. While Zohan is more of a practical fighter, the Mask warps reality. Most of the moves Zohan can do the Mask has a counter or just simply bends reality to do it better or more like a cartoon. Even Zohan's most powerful move is something the Mask perfected without hesitation. Throw a grenade at the Mask and he simply eats it and blows the smoke back at the Zohan. The Zohan tries to use a sign post as a weapon and the Mask turns it into a large sunflower. The Zohan can even call for help and the Mask would make that help do a dance. Eventually however, while the Mask wins the fight in the long run the two would probably become friends and the Mask would show the Zohan the glory of the zoot suit.
