7. Qward (DC)
Qward is a planet in the Antimatter Universe - which is a virtual opposite to the standard DC Universe - and is a direct result of cosmic tampering wrought by the Maltusian scientist known as Krona. It became a haven for the deposed Green Lantern known as Sinestro and has remained as such ever since. Sinestro took control of a group of Weaponers - Qwardian natives who forge weapons - and had them fashion a powerful ring for him, which functioned similarly to that of a Green Lantern ring, with the notable exception that it utilized yellow energy and was powered by fear. Qward's landscape is harsh and notably tinted yellow, with vast rocky mountain ranges and lava pits being the generally obvious terrain, while the yellow power battery (which fuels the yellow rings, pictured) is a focal point on the planet. The coolest thing about having Qward on the big screen would be seeing the Weaponers, the army of yellow lanterns, potentially the Anti-Monitor, as well as the landscape, but it would also mean we had expanded the DC Cinematic Universe extensively, which could only be a good thing.
