Although it had been rumored that Captain America foe Arnim Zola would make an appearance in "Ant-Man," when the film arrived in theaters last year, he was nowhere to be found. However, thanks to newly surfaced concept art, we now know that Toby Jones' Hydra scientist was initially set for a cameo.

The illustrations, by concept artist Josh Nizzi, depict four potential versions of Zola, with robotic bodies projecting Jones' face on chest monitors, a detached display, and as a floating holographic head.

Jones was introduced as Zola in 2011's "Captain America: The First Avenger," and reprised the role in 2014's "Captain America: The Winter Soldier," where he was revealed to have transferred his mind into a computer system in 1972 following a fatal diagnosis. His mainframe was seemingly destroyed when he triggered a missile attack designed to kill Captain America and Black Widow.

Zola was purportedly intended to appear in the "Ant-Man" prologue, set in 1989, alongside Michael Douglas' Hank Pym, John Slattery's Howard Stark, Hayley Atwell's Peggy Carter and Martin Donovan's Mitchell Carson. Nizzi's illustrations depict Zola's robotic body sitting at a table, so it's easy to imagine him in that S.H.I.E.L.D. meeting room.

Directed by Peyton Reed, "Ant-Man" stars Paul Rudd, Evangeline Lilly, Corey Stoll, Bobby Cannavale, Michael Peña and Michael Douglas. The sequel, "Ant-Man and the Wasp," is targeted for release in 2018.
