Then, should I bring up a theory?

Penny was supposedly a real girl, but was slowly dying away. So, in order to preserve her soul, her father created a robot in her likeness. With the help of Jimmy and Co., they were able to transfer Original Penny's to Machina Penny's body. This Gynoid, however, lacked one thing: the original Penny's memories.

To cope up with this loss, Penny's father and Jimmyborg made her into a weapon. Complete with that knife pack.

I guess Penny's appearance and death to the story, and possible up and coming appearance is... Vytal... to the plot.
