Clockwerk from the very first time before he became teh killing machine we know.
I remember when we start to see in the first game about how clockwerk appears in every different timeline, the first is in ancient Egypt and what i like is that being an egyptian makes sense for this character, since he has knowledge for preserving himself if he wanted to live forever, such as putting inside the jars some of his organs, so here is like he replaced his hand with a metal claw, as in the beginning of becoming Clockwerk.
Also his physic gives him the sensation of soemone who works out or eats well to live longer.
I hope you like this pic of Clockwerk in his early years.A pic i forgot to post up here in FA, enjoy :)
