His name came to me during a play session. Someone happened to use the word "improglio", and the character name popped into my head. With a name like that, he had to look alien, and I think a soldier with a beret and triple rhino horns accomplishes that. He certainly looks like someone from whom I'd willingly take orders.
There were several types of beam rifles to choose from in the character editor. I like his choice of the Rune Soldier rifle. Doozy's Remarkably Reliable Rifle was also cool looking.
