I recently read GL 122 and the story seemed very similar to sinestro corps war. The effigy corps came first years before the sinestro corps. Here are a list of similarities
1. They called the story "the corps war"
2. Manhunter robot and fatality were members
3. Created by an old GL villain group, the controllers (who also created the orange lantern) instead of the qwardians
4. Very similar powers
5. Had their own symbol which reminds me of the black lanterns'
I have no problem with geoff johns taking inspiration from the story but I just think he should've at least mentioned it people ask him were he got the idea all the time.sinestro corps war was not as original as you think
