The Outriders from Avengers: Infinity War introduced a new level of grisly into an already-harrowing film filled with devastation, violence and death. Marvel’s mindless horde -- with their multiple spider arms, leathery hide, eyeless visage and surprising lack of regard for self-preservation -- already seem like the perfect movie monsters, but they were once even more haunting.

Jerad S. Marantz, an LA-based concept artist and creature designer, revealed an early version of the beast on Instagram. “This one was pretty extreme, but during the design process you always want to see how far you can go before they reel you back in,” he wrote.

This version of the Outrider features the same leathery, yellow and black exterior and unsightly, bat-like mug. However, the teeth are far more haphazardly placed and jagged, and the color closer to sickly green than dirty white. Instead of eyes or empty sockets, this Outrider boasts the same blank space halfway down its head, with veins snaking curiously underneath. The creature’s gums are almost completely exposed and partially connect with the forehead.

The concept begs comparison to the classic design for Venom, originated by Marvel artists Mike Zeck, Ron Frenz and John Byrne as well as Spider-Man fan Randy Schueller.

According to Marantz, who also worked on Black Panther, Doctor Strange and Rise of the Planet of the Apes, this is only one of many concepts for the Outriders. Marantz has previously posted other designs on his personal Instagram.

The Outriders are considered a sister species to the Chitauri, the alien army employed by Loki and Thanos for the Battle of New York in the first Avengers film. The Mad Titan enlisted the Outriders in Avengers: Infinity War after the Chitauri failed to contain New York in 2012.

Directed by Joe and Anthony Russo, Infinity War sequel Avengers: Endgame opens in theaters on April 26.
