So, this is most likely the most usual attire for fussel: nothing and his labcoat.
This thing is loaded with all kinds of syringes and his trusty injector gun, as well as flooded with Fussel's nano technology, used for forcing new forms onto (un)suspecting victims!

While not being a tfee himself, he enjoys transforming others and watching them change.
If you encounter this skunk, while he's wearing this labcoat and you want to hang on to whatever species you are right now? Run.
