Trivia: Super Mario Bros. Z

  • Creator Backlash: Alvin has said that he is not proud of episode 7, as he found it too dialogue heavy and that ending was a Deus ex Machina. He also admits that Basilisx was shoe-horned into the plot and would've distracted from future battles with the Koopalings and Mecha Mario.
  • Hey, It's That Voice!: Observant fans might recognize Mecha Sonic's voice from Episode 6 onward as Cooler's, although it's just soundclips from the Budokai Tenkaichi games.
  • I Knew It: The most popular (and reasonable) theories for how Mario would be saved from Basillix involved either Shadow coming in at the nick of time or Luigi using the power of his Tanooki suit to recover from Basillix's stone gaze just in time. The first scene for Episode 9 reveals that the latter is what happens. Amusingly, some thought this theory would be Jossed due to Alvin using Luigi in that fashion for an April Fools' Day joke.
    • Similarly, this extends to portions of the fandom that expected Alvin to cancel the series due to how long he was taking with each episode after 6, especially when he kept insisting that he wanted to do 3 sagas in 15-episode installments.
  • Why Fandom Can't Have Nice Things: And you thought the Sonic and DBZ fans were already crazy. Try being a PM away from them. One feels sorry for Alvin...
    • Culminating in Alvin cancelling the series. His apology post on Newgrounds mentions that he "could blame [his] monotonous job and the impatient fans" for killing his motivation.
  • What Could Have Been: What the anime-style opening became after the series was discontinued.
    • Plot details that weren't included in the opening include: Mecha Sonic holding a tournament, a feature length episode that had Chaos as the main antagonist, the Big Bad of the second arc would be Smithy with the rebuilt Axem Rangers at his side (Smithy would have also used Mecha Sonic's parts to build an Axem Ranger Blue), and a third arc that would have featured Princess Rosalina.
