Kyle Rayner vs Any Abstract with a twist
Kyle Rayner has been granted the ability to have Perfect Will by the Presence. With enough willpower, a GL can accomplish some insane things with what has been called the most powerful weapon in the universe...a GL Ring.
Given this perfect will, could Kyle Rayner conceivably defeat most abstract entities in either DC or Marvel? If so, whom could he defeat and whom could he not defeat?
In this battle, the Presence has not given Rayner any other uber powers...only perfect will. Kyle still has all of his other regular abilities.
