Thanos vs The GLC
Thanos vs The Green Lantern Corps!!!
Thanos has taken control of the entire 616 universe using the Infinity Gauntlet. The Living Tribunal appeared to stop this at the end but, Thanos had anticipated this and using the Gauntlet manipulated Reed Richards and other great heroes and minds of Marvel into altering the ultimate nullifier to banish LT from the 616 universe. It worked but before LT was banished he was able to take the time gem from the gauntlet. He then traveled to the DC universe and spoke with the guardians about helping him restore order in the 616 universe. He explained that they would be best able to help him since all the gems were useless in the DC universe and directly on anything with the quantum signature of the DCU. However the gems are still fully effective on everything from the 616 universe, where the fight will take place. He informs them that he was able to take the time gem from Thanos before he was banished. So he will not be able to travel back in time to stop the guardians from forming the corps or the lanterns from gaining their rings. They of course agree to help him with the use of their corps. Afterwards the entire Green Lantern Corps travel to the 616 reality and fight Thanos with the Infinity Gauntlet.
So can the entire Green Lantern Corps take on Thanos with the Infinity Gauntlet if the gauntlet is missing the time gem?
Remember the Infinity Gauntlet has no direct effect on anything from the DC universe but, it can still manipulate anything from the 616 universe they are fighting in.
