9. Sinestro: Green Lantern
If you saw 2011's "Green Lantern" you should remember that Hal Jordan's arch-nemesis Sinestro started off as a Green Lantern himself. If you saw "Green Lantern" you should also know that we have support group meetings for those harmed by the film every Tuesday and Thursday but that's not the point.
The point is that during DC's New 52 reboot, Sinestro was re-inducted into the Green Lantern Corps in Hal Jordan's spot. You may recognize this as being just the worst of ideas. And you know who else did? Sinestro. This created a pretty enjoyable dynamic, with Sinestro and Hal playing the part of resigned buddy cops just trying to get the job done without having to deal with the other too much. Also, we get to watch Sinestro's old allies get weirded out by his new choice of ring and attire which makes me smile every time.
