So anyway i have been getting really back into transformers and so i decided to do something tfing related to do with that. Anyway Mark since getting kicked out and unable to best his brother magic he had turned to science and more to the specific robotics and what not. So anyway he techno wizard now and able to use his powers to control technology. He has done some modification to himself such as his tail sprays nanites that will take control of person slowly changing them. Thus they become his Robo slaves who do what ever he wants. Each one able to transform into something else usually something like a dildo or a motor bike. With his eventual plan to use them in some ridiculous plot to get revenge on his brother.

Any suggestions on what should be alternate forms of furs?
