Well, let's see. Caprice's "vectored air shield" is a straightforward usage of Maxwell's Demon. Basically, if you can control the motion of air molecules you can do all sorts of neat things, like making sure they hang around near you when you're taking a stroll through the otherwise airless vacuum of space, or (as in today's comic) having them all rush in front of incoming bullets, causing them to slow to a halt and fall harmlessly to the pavement. Handy, eh?

Meanwhile, this being the future and all, Benjamin's pistol is of course a railgun. A metal slug is super-accelerated by a pair of electromagnets, and next thing you know blammo! Before you can say "Strategic Defense Initiative" our hero is turning the attacking army of robots into scrap metal. I suspect there's more to say about this gun but I'd better keep it under my hat for now.
