***Spoiler Alert***
He couldn't, he was only able to do that because the aetherial prison he tried to trap Bahamut with left a lot of aether floating around. This combined with the prayers from all the people, infused the nearest person (that would be Louisoix) with the power of a primal, in this case, of rebirth, Phoenix. And because him being infused with so much aether, he was stronger than Bahamut for that moment. In T12 he has just a remnant of the power he had back in Cartenau, because he gave up that aether after impaling Bahamut, thinking he was successful.
