He is a prominent military general who contributed to Nathaniel Adam's transformation into Captain Atom and later becomes a supervillain after transferring his brain into Shaggy Man's body.

Eiling appears in The Flash, portrayed by Clancy Brown, and Justice League Unlimited, voiced by J. K. Simmons.

In the latter series, he is a member of Project Cadmus who later transforms into a monstrous form reminiscent of Shaggy Man using a World War II-era super-serum.

Wade Eiling first appeared in Captain Atom #1 (March 1987) and was created by Cary Bates and Pat Broderick.

After he betrays the team to their intended target, Rick Flag detonates a bomb implanted in his head.

Through his deliberate transformation into "a huge, hideous, grayish monster with superpowers", Eiling "embodies the ugliness of militarism".
