I really enjoyed this arc, but I enjoy those time-funny ones that have the plan stretched across many years. This also introduced Manitou Raven into the league, along with his wife. Because he was so powerful, JLA really didn't seem to know how to use him, thus he drifted over to JLI, then back to JLA, then died and possessed his wife (creepy!) who was sleeping with one of the other JLA (*sigh*) but he was totally cool with that (huh?).
The wife, whatever her name was, then seemed to basically fade away as they couldn't figure out what to do with her. I can't even recall what happened to her.
