Mario vs. Wario

Mario vs. Wario was a comic seen in Issue #44 of Nintendo Power and later reprinted in the Super Mario Adventures comic. It also appeared as a PDF file at the American Wario Land 4 website. The plot was about Wario, seeking revenge for Mario's "dirty deeds" such as including tricking him onto pulling up Piranha Plants in the garden, Thwomping him, and always being the Sheriff in their games of cowboys. Wario was especially furious about when they played cowboys. In their youth, they played cowboys 1,256 times. Mario was the sheriff 1,255 times. Wario was the sheriff once. And the one time Wario got to be sheriff, Mario made fun of him. When Wario mails the letter, his revenge plan is set. Mario receives it and he, too, has flashbacks, remembering all the incidents Wario remembered, but his opinion is quite different. Mario sets out, but is confronted on the way by many of the bosses from the Mario Land and Wario Land series. A humorous incident, for example, occurs when the Octopus boss from Turtle Zone in Mario Land surfaces in front of him, threatening him. Mario tells him that he should be in saltwater, not freshwater as he is now. The octopus sighs that he has, as a matter of fact, been feeling sickly, and Mario pours some salt in the water for him. But suddenly, he realizes that it was actually sugar, causing the octopus to faint. When Mario reaches the castle and pushes down the door, he finds Wario awaiting him. Mario realizes that Wario is a lot bigger than he is! After dodging his rivals enraged attacks, Mario notices a plug in Wario's overalls. He pulls it, shrinking the blown-out Wario back to size. Wario starts crying, calling Mario a "big bully". Mario cheers him up by pulling out what they used to play, cowboys! Mario immediately christens himself Sheriff and begins chasing Wario around the room, as Wario screams that he'll soon get his revenge.

Mario vs. Wario: The Birthday Bash
A second Mario vs. Wario comic was published in the magazine a year later, in issue #56.

Story
Princess Toadstool's birthday is coming up, so she sends an invitation to both of Mario and Wario. The two of them wants to give her a perfect present for the special occasion. Suddenly, the two remembered that while Toadstool, Toad, Luigi, Wario and Mario were on their way to the park, the princess saw a Samus Doll and expressed it was cute. Mario and Wario both wanted to buy the doll and give it to the princess as a gift.

When Wario reached the store, he found out that the doll was bought by a guy with a big black mustache. Wario was sure it was Mario and then, he bought a jack-in-the-box toy and asked the store owner to wrap it just like his present. The next Sunday, Wario and Mario went to Toadstool's party. While the Toads were decorating, Toadstool asked Wario to help her. When he did, she asked Mario to get the door. When Mario ran off, Wario swapped the two gifts. Then, he gave the princess "his" present. Upon opening it, Toadstool discovered a Jack-in-the-box with the toy inside of it popping out and scaring her. Strangely, the same happened with Mario's gift.

The two started fighting and than figured out that the one who bought the give wasn't one of them. While Toadstool was crying, Luigi calmed her down by giving her a gift. Upon opening it, Toadstool discovered a Samus Doll and said that it was the perfect gift and rewards Luigi with a kiss on his cheeks.
