The Yiga footsoldier's name is unknown, because the Yiga Clan is intended to be mysterious and unknown, so pretty much no one knows anyone's real name. They often have fake names, however. This one is Spike, a nickname he was given due to being...REALLY into sharp things. Like, just...Decorates EVERYTHING with sharp stuff. Lots of sharp stuff. Sells sharp stuff, can be found mumbling to himself about things he can do with all the sharp stuff...It's weird. He's kind of a weirdo.
