Steelbeak is FOWL's top agent, and a hired hand for the Villain League. FOWL's High Command trust him enough to let him do whatever he wants, letting him use all their resources for his crimes.
The past of Steelbeak is a complete mistery. Not only is unknown his real name, as well as how and why he got his steel beak. But one can guess he have done some dirty work to achieve his high position on FOWL, as well as all of his money.
Steelbeak has his own henchmen known as eggmen. They mostly wear a yellow uniform and a egg-shaped helmet. Steelbeak will send them in numbers to do the job, dealing with it himself only if really necessary. He doesn't mind doing the dirty work by himself, but since he is the boss it's him who give the orders.
Steelbeak is cool, elegant, calm and collected. He is calculated, suave and smooth with every move he makes. However, he is not one to expect the unexpected, and he knows it, which is why he tries to plan ahead as much as possible. When he runs out of options, he runs away until he figures out what to do next, which doesn't take very long. He is also very self-confident and sarcastic, hardly losing his temper.
