These two are both pretty powerful creatures who can end whole planets! Galactus is far better known and he’s almost a household name. Trigon has a lot of potential in the New 52, but at the moment, I don’t think that he could defeat Galactus. Galactus is just too powerful and he has the feats to back it up. His energy projection abilities are far superior to Trigon’s, which definitely gives him an edge. Galactus wins.
