Towers (called Fortresses in New Super Mario Bros. Wii) are a type of level appearing in New Super Mario Bros. sub-series. They are more or less the equivalent of the Fortresses from Super Mario Bros. 3 and Super Mario World. Unlike most Fortresses, in which the player may have to progress from left to right or vertically, Towers exclusively feature vertical direction. One appears midway through every world (except for World 6 and World 8 from New Super Mario Bros. as well as Rock-Candy Mines from New Super Mario Bros. U, which have two). The challenge of Towers generally depends more on traps and obstacles than enemies.
Starting from New Super Mario Bros. Wii, some worlds have no towers whatsoever. World 9 of New Super Mario Bros. Wii, the Special Worlds of New Super Mario Bros. 2, Peach's Castle and Superstar Road of New Super Mario Bros. U are examples.
New Super Mario Bros. Boss Fights
At the top of every tower, there is a boss fight with Bowser Jr., who becomes increasingly more difficult as Mario (or Luigi) reaches each Tower. When Jr. is defeated, he gets back up and jumps off-screen (and out of the Tower). Additionally, the first time Jr. is defeated in each tower, a brief cutscene ensues on the map, showing him running with Princess Peach to the Castle of that world. Some worlds have 2 towers.
New Super Mario Bros. Wii Boss Fights
At the end of the fortresses, there is a boss fight with the Koopaling of that world. After defeating it, it flees to the castle at the end of its respective world for a rematch. In the last tower, instead of a Koopaling, Kamek is fought instead. After defeating him, he flees to the Airship. However, he is not fought there again.
New Super Mario Bros. 2 Boss Fights
At the end of every tower, there is a boss fight with a group of Reznors. After defeating them, the Koopaling of the world swings in with Princess Peach in hand, except for World 6, when the game just cuts to the world map.
New Super Mario Bros. U Boss Fights
At the end of the first six worlds' towers (excluding Rock-Candy Mines' second tower), there is a boss fight with a Boom Boom, who, after Acorn Plains, has Kamek enhance it's abilities. After Grinding-Stone Tower, the bosses of the towers Screwtop Tower and Slide Lift Tower are replaced by Boss Sumo Bro and Kamek respectively.

Super Smash Bros. for Wii U
A tower, particularly the Slide Lift Tower level, appears as one of the variations of the Mushroom Kingdom U stage in Super Smash Bros. for Wii U, featuring two moving platforms that derived from said level. Like the other sections of Mushroom Kingdom U, different obstacles such as icicles and Water Geysers appear as stage hazards.
