This is Luke before he trains with Yoda
Han Before the Battle of Hoth (not that he really changes much between ANH and ESB)
Location: Coruscant Slums (a place neither are familiar with)
gear: Lightsaber for Luke, standard gear for both.
Expanded Universe (EU) allowed. i have never read any book for this time period but feel free to pull feats from any books/comics you wish. (provided they are feats from before the set versions of the characters).
Round 1: Luke vs Han
Round 2: Chewbacca and Han vs Luke
hope this hasn't been done before, i searched google and didn't see it and used search function on Comic VIne but kept getting an internal server error.
