Vs. Mega

In certain bonus challenges of Mario Kart Tour, the player must race against a mega-sized driver. These challenges are titled "Vs. Mega" (also written as "vs. Mega") followed by the opponent's name. The default title of this type of bonus challenge is Vs. Mega Bowser, with Bowser most often acting as the giant opponent, although many Vs. Mega bonus challenges have featured other opponents, including Dry Bowser, Donkey Kong, Wario, King Boo, and Metal Mario. Hammer Bro, Nabbit, and King Bob-omb made their first appearances in the game in this bonus challenge.

Mega-sized drivers have the ability to crash the player upon contact and pass through certain obstacles unfazed (as drivers can do in regular races under the effects of a Mega Mushroom), while also being able to produce items without relying on Item Boxes. Additionally, they can throw Bowser's Shells and Giga Bob-ombs backwards. In some Vs. Mega challenges, the player must also race against a number of regular-sized drivers beside the giant opponent. To clear a Vs. Mega challenge, the player must finish the race in first place.

As with regular races and Big Reverse Race bonus challenges, Vs. Mega challenges require the player to pick a driver, kart and glider from their own roster instead of giving them set items to use like most other bonus challenges. They can also select the speed class, which determines the difficulty of the challenge; for instance, higher speed classes may present additional opponents or add stronger items in the mega-sized opponent's item pool. The speed class also affects the number of Grand Stars the player earns from the challenge upon clearing it: one Grand Star is awarded for clearing the challenge on 50cc, two for 100cc and three for 150cc or 200cc. Vs. Mega challenges often appear in the last cup of the tour.

The following is a list of Vs. Mega bonus challenges sorted by course.
