Class 5 faust. this one is made to mimic Grand Arms Shinobi. Class 5 had great ability and it was not uncommon for them to have their own customised faust to go along with their design motifs.
Another class 5 faust this one was made to mimic a smaller Sturmtiger. Showing the kind of ability that could be put into a class 5 faust, this one is capable of producing its own units. In this case reflective faust and teleporting missile pods.
