Leviathans cannot go through the portal. Only spiritual beings can. Leviathans are physical beings. EmpyreanSmoke said so himself.

Zachariah did say that. He said God was the general. It was in the season 5 premiere.

Leviathans negate angelic power by cutting their connection to Heaven. How the hell will they do that when angels are in heaven itself?
