Apokolips now. 🙁 IMO, Darkseid's worst showing in awhile. and the only one in recent memory with no extenuating circumstances or PIS. Great arc for Supes and the Aegis, bad arc for DS. Only upside is it showed DS can control souls.
Someone, I think it was illagrok, mentioned Identity Crisis and Deathstroke. IMO, that's one of the few things in DC you have to give almost everyone a pass for. Slade gets a pass on alot of shit that could be considered PIS on closer scrutiny. So losing to him isn't really a low showing.
Orion during Morrison's run on JLA. One of the few things that 'The Mad Scotsman' really botched.
