Frank Adversego is a cyber-security expert.
He is one of the very best. Just ask him, he'll tell you.
Granted, he is a genius and truly is phenomenal in his field and actually getting better as time goes by but when we first meet him he is considerably (well, completely) full of himself and carries a pretty large chip on his shoulder about the fact that other people might not see just how great he is.
If that all makes him sound terrible, then good. He is pretty terrible.
When we first meet him.
He will improve very quickly after things start happening to him. He will pretty much always be pleased with himself and prone to slapping himself on the back a lot but he stops being such a jerk and becomes a fascinating character to follow. Add to that the fact that he is always meeting interesting people that throw him off now and then, though he rights himself well enough, and you have interesting dialogues.
Most importantly he keeps getting involved in all things cyber-related which, considering how much the Internet controls things today, is pretty much everything. In the first adventure there are people getting into the most protected data storage and deleting file; removing them from existence. The second is even more frightening with the elections being more and more electronic and easier for manipulation by the ultra-gifted. Another will talk of the power grids and how interconnected, through the Internet, they are. One deals with artificial intelligence and how safe is smart computers. And the latest craze of cyber-currency gets attention as well.
All this means that Adversego will be a very busy man.
