Trion has no chance against Juggernaut. Most magic users (including Gods like Chthon) use dark magic by incantations or generating the power from another source. Shuma-Gorath generates his own mystic power and can drain magical and non-magical energy from others. His reality warping powers are on a magnificent scale - Trion would have no chance.
Shuma Gorath>Cyttorak. As such he'd easily be able to take on Trion, as Cyttorak is the source of Trion's power.
Is this a joke or something? Shuma has pawned easily all three Vishanti at the same time ( three fully-fed Galactus powered beings). Demons at the scale of Mephisto and Satannish were stated to be "ticks" when compared to Shuma. Trion Juggy is strong without a doubt, but he would be basically taken apart here.
