A Yiga footsoldier who... strangely hates mighty banana's till death. She traveled far, FAR away from the Gerudo Yiga clan hideout to reach Eldin, where she plans to... throw as many bananas as possible into Death Mountain's pit. She really felt like an outcast in her own clan. Unfortunately she couldn't accomplish her journey due to the Divine Beast Rudania going nuts. She still follows her own Yiga duty to hunt Link down, and if she succeeds maybe Master Kohga and the other Yiga's could accept her more as part of their clan...
They will resist if you ask the reason of their deep hatred for banana's, because typically other Yiga's would tell her she's childish. Fuz can be very sensitive to criticism or comparisons, she is desperately seeking for the approval of others. Outside her job, Fusie is a curious person and wonders if she can have a new life in Kakariko village, but it would be too risky because the Yiga clan doesn't like betrayal and consequences can be deadly.
