10 Insane Times Superheroes Teamed Up With Their Worst Enemies

6. Hal Jordan & Sinestro - The New 52

Hal Jordan and Sinestro were once allies as two fellow Green Lanterns. Unfortunately for Hal - and for the rest of the Lantern Corps, sadly - Sinestro became enthralled by the Power of Fear (represented by the colour yellow in the comics) and consequently became Jordan's greatest living enemy.

Despite this, and the fact that Hal even killed Sinestro during a particularly... shall we say, testing time in his life, the two have put aside their differences and fought side by side as friends on numerous occasions - the most famous of which occurred during the first run of GL comics in DC's New 52 reboot.

Written by Geoff Johns and drawn by Dough Mahnke, the first arc of the series saw the two Lanterns come together to tackle a larger, and indeed looming, cosmic threat. It's the kind of threat that tends to see heroes come together with their adversaries, but nevertheless, even as DC struggled to find a voice in 2011, Green Lantern's unlikely team-up resonated for all the right reasons.
