Trigon is one of the most powerful threats in the DC Universe, but he only seems to ever bother the Teen Titans. Now cosmic tyrants seldom suffer other cosmic tyrants who can rival and threaten them, so it's curious that for all the time he's appeared in DC Comics, Trigon has never run afoul of such cosmic peers as Darkseid, the Anti-Monitor, Parallax, or Imperiex. Wouldn't Trigon perceive these entities as rivals/threats who must be confronted and eliminated? For that matter, wouldn't those entities also treat Trigon as a threat that must be dealt with? For some reason, their paths have never crossed.
