"Trigon's Seen Better Days" from Titans vol.2 #2 (DC, 2008) by Judd Winick, Joe Benitez and Victor Llamas
And so has this franchise. I guess it's convenient that the Titans can keep shuffling between Teen Titans and just Titans, getting cancelled and going back to #1 each time. This is the series that was turned over to some villains after they killed the Atom, Ryan Choi. Somebody still needs to explain to me what the hell DC was doing there. Not just with the Atom's death (because they sure didn't put Ray Palmer to good use after that), but with using the Titans brand to create a low-rent Secret Six or Suicide Squad.
