An artist's rendition of the Shrike creature from the Hyperion universe. Credits for the 2D design: https://www.reddit.com/r/Hyperion/comments/1ho36we/i_finished_the_first_two_books_recently_and_i/

The Shrike, also known as the Lord of Pain, Avatar, Angel of Final Atonement, Angel of Retribution or Angel of Retribution from Beyond Time, was a legendary and seemingly indestructible being of incredible power and strength, and of dauntingly imposing appearance, who was created in humanity's far future and sent back.

This is the second version I created as a 3D model, one of the most realistic, with the creature characterized by its four arms and many spikes.
