Super Mario: 10 AMAZING Features That Only Appeared Once

10. Mario Vs. Luigi Mode - New Super Mario Bros. DS

The Super Mario Bros. series has had a bit of a hit-or-miss record when it comes to it's games' bonus features, which is strange given the fact that they hit the big time during the very first title.

New Super Mario Bros. for the DS brought with it a couple of unique bonus modes players could run through once they were tired of the main storyline. Most of the mini-games from Super Mario 64 DS returned again, however the highlight was undoubtedly the Mario Vs. Luigi mode two players could take on.

The game mode features both Italian plumber fighting it out for stars, and can take place across five specially designed levels based on some of the themes from the main game.

The mode is absolute chaos, side scrolling wildly and requiring players to either jump or ground pound on each other to steal stars.

Power ups such as Stars and Mega Mushrooms are thrown into the mix, adding to the mayhem and making this one of the most addictive features in any Mario game. Making use of power ups and two screens as well as multiplayer action, it's baffling to think this awesome feature never returned.
