Ok, Spider-Man is a good guy so he probably wouldn't kill Darth Maul but I can guarantee you the Sith is playing for keeps.
This fight is goes down at the San Diego Comic Con. Everyone from Disney Princesses to Thanos are asked to weigh in on who they think will be victorious.
If you just want to see the fight go down, you can skip to the 6:50 minute mark where the fun begins. You'll have to watch the video to find out who wins.
