These scans are from New Titans #84, part of the Wildebeast story arc. The Titans have been captured by Jericho. Nightwing spends the entire issue with his costume in tatters! He's uncharacteristically hairy here, maybe he forgot to shave? Also, the captured Titans appear to be wearing diapers, but this post mainly features their shirtless fearless leader.
Edited on 9/26/16 to replace old images with better quality scans.
