Blue Alloys are members of the Fighting Alloy Team that appears in the Wii video game, Super Smash Bros. Brawl, in the mode Multi-Man Brawl. They can be collected as trophies, just like all the other alloys. Their attacks are the same as Zelda's, but without Special Attacks. They can be used as playable characters using hacks.
Blue alloys appear as skeletal versions of Zelda, with a long pony tale sticking out of the back of their sphere like heads. Like all alloys, they have big white spheres where their faces should be, and other ones for fists and heels. The team's characterized wire sphere is located in the middle of their bodies.
