Legolas is a Prince of Mirkwood. The best archer in Mirkwood for that matter. He is MUCH MUCH more accurate than Robinhood. Legolas can kill him even without his bow!
Everyone knows how much stronger elves are than men and Legolas is a skilled warrior which makes him more deadly. Sorry, but RobinHood has NO CHANCE WHATSOEVER agaisnt any elf, expecially Legolas! Go Legolas!
