Broken Base: There are some fans who really didn't care for Peach in this comic. The implication that a female character can only be strong if she's Rambo in a dress rubbed some the wrong way. Plus some also see the scene in which she threatens to blow up herself and her friends just to kill the Koopalings as her Moral Event Horizon.
Writer/translator Leslie Swan, who worked on the Super Mario Adventures comic, has voiced two female characters in the Mario series: Peach and Mona from WarioWare. Now note the sequence where Peach shows up as part of a pizza delivery, matching Mona's employment in Twisted. Better yet, the delivery was made by Yoshi, making him a Pizza Dinosaur.
Inferred Holocaust: Try not to think about the implications of dozens of Boos, complete with a Big Boo, who can't be stopped by staring at them, and have no problem leaving their abode even in broad daylight. And they're still on good terms with Bowser. Hopefully they won't take advantage of this.
In the first Mario vs Wario comic, Mario is revealed to be only 20-something years old (It's been 20 years since he saw Wario, last time he did they were small children), long before Super Smash Bros. Melee confirmed that he is 26.
Bowser has a Magikoopa as an advisor, four years before "Kamek" was introducednote "Kamek" is the name used for all Magikoopas in Japan..
This comic was also the origin of "Weegee" (used here as Mario's affectionate nickname for Luigi), long before the Mario Is Missing! memenote Or the Mario and Luigi RPGs, for that matter. In the second game, if Baby Luigi is knocked out, Baby Mario will cry out "Weegee!!"..
The Koopaling's hairstyles were reused in Mario & Luigi Superstar Saga, keep note that this was during the debut of Super Mario World and the Koopalings hadn't received their updated looks yet.
