Chris R./Roy Mustang
I believe that I qualify for all of the above. Allow me to introduce myself. I'm General Roy Mustang, the Flame Alchemist. As an alchemist, I have training and a keen understanding of bioengineering, genetic studies and other such related fields, especially chemistry and biochemistry. I'm also a full General in my country's military with a bid to become leader of the military in the near future. And, of course, I have weapon training as well.
So, I'm curious, what sort of business are you looking for?
