Back in school I read one book that caught my eye. It was about a man who could change his looks, nothing like werewolves or shapeshifters; he was described as having scars all over his form and would hide himself with a mask, or later on a mesh netting. He was an agent for the government or a special group. The most notable part of the book is the inclusion of the Nautilus submarine, an underwater base, and an invisible man. I don't remember the name of the book but this story has stayed with me for years and it annoys me that I can't remember the name.
Your character has many points in common with the Avenger, by "Kenneth Robeson". There are several books in the series and one might well feature an underwater base.
The Avenger was involved in an accident that left him with white hair and completely pliable facial features. And being filthy rich, he goes Batman, founding a special group to fight crime, "Justice Inc.".
