Characterizations

This post serves as a notepad for characterization choices I've made regarding Leon. These can very quickly change based on future dlc and expansions upon the Katana ZERO world.

The Facts
He's missing is right arm below the shoulder.
...Which makes him left handed.
He can aim and shoot a rifle with one arm.
The concept art shows him as quite muscular.
He wears the NULL project clothes, minus cape and hat - all this implies he's a military man.
He is the only one outside of manufacture who can make Chronos - implying he's a chemist.
He threatens to kill anyone who is at the door of his domain.
His only regret is that the experiment failed - this implies he's low or no empathy.

The Characterization
Touch averse
A psychopath rather than simply low/no empathy - is consciously aware of attachment, feels them less
Gets lost in his work very easily, to the point he forgets to shave or sleep
Speaks in a very calm and collected voice, generally sounding disinterested
Speaks carefully in a measured cadence, typically to ensure he is understood
Tends to keep his face quite neutral and collected. He'll smirk if he feels confident
