Volthoom has straight up stated that Hal has more willpower than frigging central power battery and used his willpower to unravel the entire universe from start to finish.
At full throttle he has even stalemated Sinestro (One of the strongest Lanterns ever who has even tamed life entity with willpower AND broken a GL ring THRICE with sheer willpower) amped on fear of a planet AND Parallax entity.
Nekron thing is total PIS, considering Johns himself established Black Lanterns aren't even reanimated corpses, but facsimiles. Hal shouldn't have been able to do anything, because that wasn't supposed to be Hal.
Not the first time Johns has retconned himself, though.
