Breath of the Wild was a very important Legend of Zelda game for many reasons, not the least of which was because it pushed the franchise into new and exciting directions. One of these directions was DLC, which the series had never had before. In the second DLC pack, called The Champions Ballad, new dungeons, new story addtions, and items were put into the game. One of them was the “Master Cycle Zero”, which was meant to be Link’s version of a Divine Beast like the other Champions had.
However, as players really looked at the bike, they noticed it looked a bit like the Master Cycle that Link got when he became a part of the Mario Kart series via DLC in Mario Kart 8, and in the full version of Mario Kart 8: Deluxe. Turns out, that was accurate. As Eiji Aonuma himself confirmed the “borrowing” of assets from that game.
“When we were thinking about this motorcycle, we thought it should be something from the past. It’s using ancient technology. Perhaps it’s like the first Master Cycle, is how we kind of approached it. When we were making the game, we did actually borrow assets from Mario Kart, and kind of just had it run through the Hyrule world. It got kind of a test drive, really.” he said to IGN.
The Breath Of The Wild director, Hidemaro Fujibayashi, was also in on the interview, and noted that while they did take assets from the game, they made it their own “conversion”, especially since they had to shape it to fit the style of the world, and the function it needed to have in order to cross a lot of the terrain in the game’s version of Hyrule.
Either way, it’s a cool addition, and one that fans are no doubt enjoying.
