YMMV / The Fantastic Favio Bros

• Anti-Climax Boss: LeTony and MaCavio merge into their ultimate being... but are so unable to function that they instantly fall over and are defeated.
• Big-Lipped Alligator Moment: In one scene of A Powerful Foe, Tony approaches Favio to warn him about the presence of alcohol at the party - with a sword sticking out of his back, and obvious signs of pain. Once the camera switches angles the sword is completely gone and never mentioned again.
• Early-Installment Weirdness: Due to the series' start as a pair of school projects, not much was set in stone early on. LeTony in particular didn't have his iconic voice in the first movie (more closely resembling his actor's actual voice), while the second movie had him sporting a fur coat instead of his iconic leather jacket (which, oddly enough, was in the first movie). The third movie would combine the outfit of the first with the voice/personality of the second, which would stick with him for the rest of the series.
  • The cast was also much different back then. Bububaba was built up to play a more major role as an overarching villain, but would fall off in prominence after another voice-only cameo in "Salvia is Not Our Savior". MaCavio was another example, being a main cast member in the second movie and was foreshadowed to come back at the end of the third, only for that to not pan out. Both examples are due to the two-year gap between "A Powerful Foe" and "Salvia is Not Our Savior", and once the latter was released it solidified into the modern Favio/Tony/LeTony/Boom Mike quartet that the franchise would stick with.
  • The naming scheme of the cast was meant to be "bootleg" versions of Mario characters (Favio = Mario, Tony = Luigi, LeTony = Waluigi, etc), but this trend would later drop off, with characters like Boom Mike and The Chrises having no Mario equivalents.
  • The production value of the movies would also amp up significantly in the gap between the third and fourth entries.
• Like You Would Really Do It: Tony accepting drugs in a health movie? Yeah right.
• What Could Have Been: A movie based on counterfeiting money had started production. Aside from a scene of Boom Mike counterfeiting money with some green crayons (and subsequently using them as napkins at a pizza restaurant), not much of the movie was made.
  • Another movie involving the Favioverse equivalent of Peach was in production, but only a small portion of it was filmed, which has since been lost.
