Clash, essentially created in a laboratory in 1914, was only eight years old when he was sent to war... 

Clash is a 22 year old-- harsh German accent (occasionally punctuated by a few German words )  that comes across with a guttural growl, owing to the fact that he's half behemoth. This deep, throaty quality adds to his intimidating presence. Despite this scary persona, he is more gentle natured and even sentimental to other people's situations. He often has shorter lines as he's not too talkative. Whether it be out of shyness or being reserved.

It's expected that some computer edited will be added in to make his voice sound more monster-like. Without it being so campy.
