Fox McCloud
Okay, let’s get past him being a fox. But our furry, space-traveling hero carries some core damage that many humans can relate to. Fox’s father issues are what make him passionate. His galactic endeavors are driven by that deep void, and are the source of his firmly rooted compassion.
JC Denton (Deus Ex)
The nano-augmented hero is intelligent and idealistic. He strongly believes he is helping the world, and has the tools to make the task of being a Doctor easier. He can become invisible, change his immunity, or use night vision if he needed to.
Professor Layton
Professor Layton is one of those heroes that probably has less than six degrees of separation from all the previous Doctors. The English gentleman already fits the bill solving crime, and had a taste of time travel in Professor Layton and the Unwound Future.
