Where the real Clockwork is the sunniest man on the planet, Doppel takes a far more sinister personality - Dishonest, blunt, rude as hell, and promiscuous. Doppel takes all the hidden and buried qualities of his real self, mirrors them, and blows them out to painful degrees. While he might be nice to people he likes, make no mistake - He is a horror to be around and makes certain to be so. 

It's hard to find a moment where he's anything but malevolent and hostile to anyone who interacts with him. As such, really, it's suggested to steer clear for as long as you have to.

Stealth 

Being small isn't all bad! You can hide in corners!  You can hide in closets! You can hide behind the couch and then scare the everliving shit out of your dogs on accident!

Pickpocketing 

With a thief comes quick fingers - And this one is an absolute menace about it. The first thing he does with most people he gets to know is to find out just how perceptive they are, and the favourite way to go about it is to find out just how quickly they'll notice a missing object from their pockets.

Mirror-travel 

One of the most inherent traits to doppelgangers - The ability to travel between and to-and-from mirrors. They are also capable of entering and leaving the 'real' world for the mirror world through the mirrors, and are also capable of following people from their reflections in mirrors or glass.

Cartography 

A successful heist isn't a successful heist with the most intricate map of the layout of your house. Spends a lot of time mapping out random locations he intends to heist, or just mapping out the surroundings of the city he lives in. Just in case, you know.

Nobody knows how doppelgangers are created, though they typically happen to the particularly dishonest. They show the traits that they most would like to hide as their most prominent features to their personalities, showing a side to a person who wants to keep those parts of themself buried deep down.

And 'Doppel' has existed for longer than he can recall. 

Present day

Doppel, or as he calls himself, just Clockwork, is the 'doppelganger' to Clockwork LaFontaine - And he's existed for too long to not be jaded towards existence. He's been a part of the mirrored world of London for a long, long time, and pretty much lives his own life in the same strides as his 'original', though with stark differences in attitude, personality and outlook on life. 

When his husband disappeared from his life, and he remained uncertain of his fate for a few years, he sought out the 'real' version of London, passing through mirrors and reflections of his original self. His motives are unclear to the real Clockwork, though his intent to murder his original are clear as glass - And whatever motive he has, it's fueled by spite, malice and jadedness. 

Enjoys freaking out his real self through the use of mirror and glass reflections.

Does not own the trademark red scarf that the real Clockwork is so known for - It's an easy way to tell the difference in a single gaze.

Does not emote as much as Clockwork does - Usually just has an annoyed face or a smirk, but not much else.

Causes an odd phenomenon described as 'mirror eyes' when he possesses Clockwork - It just turns 'their' eyes into a colourful, reflective 'surface.

Married his husband far before his real self married his husband - Which is one of the points their lives differ.

Also does not have a daughter unlike Clockwork, due to children usually not having doppelgangers... Unless there's something wrong. As a result, however, he does adore to spend time with the Kirin of the real London and acts as a 'babysitter' from time to time.
