Yes. Major Force is possibly the most killed villain in the DCU....
*Superman/Batman as you noted, he is drained to nothingness.
*Battle for Bludhaven where Monarch/Atom Drains & absorbs him completely.
*Green Lantern 60 - Guy cuts his throat. Dead.
*Guy Gardner:Warrior - Guy uses a singularity bomb on him that implodes him to nothingness.
*Green Lantern - Kyle decapitates him and sent the head into deep space.
There's maybe more than those examples but each one of the above represents a very final end for the character.
...in the first issue of Blackest Night that just came out, we see Hal and Barry looking at the Justice League villain morgue and who is there? Major Force (see scan). Are the editors even trying any more?
