The Waluigi Arc

The Waluigi Arc (sometimes called Waluigi's Rejection or Waluigi's Rejection Arc) is the official term for an arc in the current series on SMG4's channel. It's a series of videos by SMG4 that are part of a story involving Waluigi obtained his secret power after being rejected in a Smash Bros game for far too long, thus becoming a major villain (as well the main antagonist) of the SMG4 series and ultimately taking over the channel.

Trivia

 * As a tie-in to the arc, starting with Mario SAW, Waluigi appeared on SMG4's channel banner, and as the videos progressed, Waluigi got closer and closer to the front of the banner. He is now currently in front of the disappearing SMG4 logo, and the other characters (Mario, SMG4, Fishy Boopkins, Meggy, Luigi and Bob) are fading away.
 * Despite being released months before the Waluigi Arc was even conceived, SMG4: Mario waits for pizza is canon in this timeline as confirmed by a flashback in SMG4: The Mario Convention!
 * After SMG4: The Mario Convention!, an official playlist for the arc was created in SMG4's channel.
