Mario & Dax: Epic Tag Team Takeover

Mario and Dax: Epic Tag-Team Takeover, known in Japan as 'Kaburamu! Mario to dakkusuchīmuappu' (カブラム！マリオとダックスメガチームアップ) is a 3D multiplayer platforming video game developed and published by Novascopic Digital Networks and Nintendo, marking the first time both company's have ever collaborated together (each individual company currently compete in the video game market with their respective consoles). The game is a crossover between Novascopic's The Heroic Quest of Dax, with elements of the popular Super Mario series mixed in.

The main plot of Mario and Dax focuses on the Beast of the Sword (from THQOD), Ganderous, teaming up with Bowser for plans to destroy the worlds of Skyland and the Mushroom Kingdom. Their power creates a rift in which Mario, Luigi, Yoshi, and Dax have to defeat in order to restore order.
