These are two of the most powerful heroes on either side, and it would seem that in a fight it's their powers who would match up against each other pretty well. In the one corner you've got the Vision, aided by the Mind Stone, who's capable of firing off extremely strong energy beams and has a super durable android body. In the other corner you've got Scarlet Witch, who is capable of all kinds of mind sorcery, including telepathy, telekinesis, and even mind manipulation. Will that work on Vision? Only one way to find out. She's also capable of firing off some pretty great energy blasts of her own, so the two should be able to go toe-to-toe. Another reason this is an intriguing fight is because in the comics the pair are actually a couple. They fell in love while fighting for the Avengers, got married, and even had a couple of kids (although of course happiness didn't last for too long). That could be a road they eventually go down in the MCU - heck, maybe they're already on the way there at the beginning of Civil War - so there should definitely be an extra bit of spice to this one. Who will win: Draw - they'll realise their true feelings for each other and stop fighting to go have weird android babies.
