Hyrule Castle

Hyrule Castle is the seat of the Royal Family of Hyrule in the The Legend of Zelda series. It has appeared on several occassions in which the Mario series has crossed over with The Legend of Zelda series.

Super Smash Bros. series
In Super Smash Bros., Hyrule Castle appears as a lengthy stage based off of how it appears in The Legend of Zelda: Ocarina of Time. In single-player mode, Hyrule Castle is the first stage the player battles on. During gameplay, a whirlwind appears about every 30 seconds; any character caught in it is blown upwards, and sometimes out of the stage if sufficiently damaged. The castle also has a little shack at the far right end of the stage, which may act as an additional platform. This stage serves as Link's home stage in the game.

In Super Smash Bros. Melee, a similar but much larger stage called Temple takes its place. Hyrule Castle, in its The Legend of Zelda: Twilight Princess incarnation, also appears in the background of the Bridge of Eldin stage in Super Smash Bros. Brawl and Super Smash Bros. for Wii U.

In a Nintendo Direct that premiered on June 14, 2015, Masahiro Sakurai revealed that developers have been working on porting Hyrule Castle (along with Peach's Castle) into Super Smash Bros. for Nintendo 3DS / Wii U as downloadable content.

Mario Kart 8
In Mario Kart 8, Hyrule Castle appears as part of the Hyrule Circuit course in the The Legend of Zelda × Mario Kart 8 downloadable content pack. As the castle is surrounded by Zora's River, racers access it by gliding from Hyrule Field to the castle's roof. When racers enter the castle, they drive down a curved staircase into a large chamber that houses several Rupees and the Master Sword resting on the Pedestal of Time, surrounded by several stained glass windows. If racers are able to hit all three Spin Boost bumpers on the way down the staircase, a small Boost Pad ramp appears in front of the Pedestal of Time; if this ramp is used, racers can get an additional speed boost by touching the Master Sword. When exiting the castle, racers drive over a bridge and onto a path leading into Hyrule Castle Town.
