whatever the case is Darkseid is somehow involved for sure (after seeing Desaad in season one), somehow Conner has learned a lot more about New Gods in the last five years aswell revering to the Supercycle as the New Genesphere (its original or New Genesisian name)... also the boom tube that was used transver Supercycle to Earth was also referred to as the Light's "new partner's delivery" system in s1e 'Bereft'...

But to be honest I never consider Mongul at all and it could quite possibly be him, his body shape suits the silhouette and they can shape his backstory to fit YJ storyline quite easily
