Unique Sci-fi Time Traveler Name

I’m writing a story about time travel. I’m having trouble coming up with names for futuristic characters, specifically the lead. He is intelligent, brave, and mysterious. I need a unique name that reflects his traits well. Thanks!

Haha. The [name_m]Doctor[/name_m]?

Seriously though, we need more information than this to help. Look at the guidance thread.
