Mostly deals with puppets but is able to use the normal subsitution jutsu/ shadow clone if needed.
Has two puppets, named: Odokemono (meaning Joker) and Kouhi (meaning Queen). Mostly uses Odokemono.
There are countless weapons hidden in Odokemono seeing as he was made by none other than Sasori.
Fuyuko does have a Kekkei Genkai called "Mind Speak" and it works like this:
What this is, is a powerful tool that is able to distract the enemy, and/or find them. The Katsu clan is able to basically read minds and communicate with their minds. All they have to do is see a picture of the person they need to connect paths with, and they are able to. During the time that they are connected to another person (it does not have to be another Katsu member, it can be with anyone and they are still able to communicate), they become unusable. Meaning, they are not able to fight or defend themselves. Their attention much strictly be kept on the open pathway, and nothing else.
So, if she is ever connected to someone, she's useless, so she rarely uses it when she's alone.
Though, she has had training and can defend herself with Taijutsu when her puppets are not out
What Odokemono can do/looks like: Odokemono looks almost like the Joker from Batman. Dawning the same facial expression. There are countless weapons within him and he has nozzles on each of his palms, allowing fire and water to come out of them. (( Yes, like Sasori ))
Kouhi: Kouhi usually always has her eyes closed, and she has long black hair. She also has the weapons inside her, and the nozzles, though they are used differently. She is able to produce electricity with her palms, symbolizing the chidori. When she opens her eyes, they are ingaved (Which Fuyuko did as a tribute) with the Sharingan. Symbolizing that she cares for the Uchiha clan.
