Both. Wario will use his atomic farts and Bowser will use fire and burn the gas fumes. ITS A TIE!
Yoda!!
I'd bet on Bowser.
Dr. Eggman
it would be a tie because Wario is more stronger and powerful than Mario but Mario has more skills and abilities than Wario also Mario can turn into Super Mario and Wario can turn into Wario Man.
Wario will win i know he will
In a fight between Luigi and Bowser Jr, Luigi would most likely win.
Bowser
Donkey Kong has agility and brute strength, Bowser has a spiked shell and can breath fire. So using common sense Bowser should win, but due to nintendo's standard of "good guys finish first" Donkey Kong would probably win.
Bowser. Sonic sucks. And Bowser has awesome spikes on his back
Bowser. Chcuk Norris right now is an old movie star, while bowser hasn't aged in years, and he's a freakin' dragon/ monster turtle/ gorilla/ tiny Godzilla.
Donkey Kong. Donkey Kong Is More Powerful And Is Also Much More Intelligent Than Bowser. Bowser Has A Spiked Shell And Firey Breath. Donkey Kong Can Use His Clap Attack That Can Have The Wind Blowing Bowser To Some Lava.
Mario
