Like a blank clockwork 

This is the oc I made to ship with your oc sona 

They will help sona with work and work for her she was made to help sona with inventions and such. They can be male and female they have a male form or can just switch their genitalia so they can have babies or make others preggo so yeah

She doesn't really have a face other then that but the clockwork face can switch to show different things and her hands can turn to weapons and tools
