First one is that Golgotha, Etrigan's child (Etrigan himself descended from Trigon) one shot Michael and he claimed that both of their powers have the same source, so the same applies to Trigon.
All that is already a stretch, but it falls apart when you notice he just killed a random angel. It's never said to be Michael.
And then there's the later part where Belial, Trigon's son, imprisons Lucifer and turns him into a dog. The big issue here though is that this was early New52 Lucifer who clearly wasn't a continuation of the Vertigo one (at least not at that point), so he has no real big feats.
