Batman is off to a good start in the this new Rebirth continuity, at least beefcake-wise! In Batman: Rebirth #1, we see a scantily clad & sweaty Bruce wait doing pull ups using the Wayne Tower helipad. Holy fanservice, Batman!
In Crisis on Infinite Earths #11, a bare-chested Superman from Earth Two wakes up from a nightmare. Special thanks to George Gustines for this pic. Please visit his awesome Facebook Byline Album & follow him on Twitter: @georgegustines.
It's Battle of the Spidey clones in Spiderman: Redemption #1! Kaine (the 1st clone of Peter Parker) tracks down & attacks a shirtless Ben Reilly (another Parker clone also known as the Scarlet Spider).
Secret Origins Annual #3 is a Dick Grayson beefcake extravaganza! The whole issue is basically Dick having an extended nightmare while bare-chested in pajamas, drawn by various artist! Enjoy. Edited on 6/20/18, images replaced with better scans.
