What can Thanos do with a GL Ring?
Senario:
3 Unknown Lantern came to cross path with Thanos, he defeats one and see the ring ran off as the Lantern dies. He became interested and captured the remaining 2.
Thanos, being Thanos, subdued the 2 rings and and learned their power source and how to manipulate it.
With 2 ring equipped, he decided to invade the Central Battery.
Thanos has 2 weeks prep.
Can the LANTERNS defend their own?
PS. CURRENT LANTERNS AND GUARDIANS.
