It's been well over a decade since players have seen a 2D platformer for the Wario series. One of the last entries came out in 2007 under the development of Suzak called Wario: Master of Disguise.

The plot revolves around Wario's jealousy of a TV thief named Silver Zephyr. He decides to create a helmet that will allow him to enter the TV show and, upon successfully doing so, steals the thief's disguise. This game took a more puzzle-oriented approach to the platformer with players being tasked to move with all other buttons as they complete actions on the touchpad.
