Williams will make his live-action debut in the upcoming Disney+ original series Wonder Man, set in the Marvel Cinematic Universe (MCU) and portrayed by Yahya Abdul-Mateen II.

"[7] Wonder Man later appeared as a founding member of the spin-off West Coast Avengers first in a four-issue miniseries (September – December 1984), and continuing as one of the primary characters in the series' 102-issue run.

Comic book writer Rick Remender revealed in an interview that Wonder Man would be a member of the Uncanny Avengers, starting with issue #5.

Simon, desperate and blaming Stark for his predicament, accepts an offer from the master villain Baron Heinrich Zemo.

[volume & issue needed] Eric Williams becomes distraught over the apparent death of his sibling and, blaming the Avengers, assumes the identity of the Grim Reaper in an effort to destroy them.

The Grim Reaper steals Simon's body at one point,[10] and attacks the Avengers three times before Wonder Man finally returns.

[11] Wonder Man remains in suspended animation for years, and it is during this period that Ultron, the evil robot creation of Hank Pym, steals the brain patterns recorded by the Avengers for use as a template for the synthezoid Vision.

[17] After this encounter, Wonder Man was restored to true life and chooses to remain with the Avengers, aiding them against Attuma and Doctor Doom.

[19] He soon after defeats the Grim Reaper, who was intent on destroying the Vision as he was "artificial" and a "mockery" of his brother; Wonder Man at this point is revealed to have become a being of ionic energy.

[34] Wonder Man takes part in the Kree/Shi'ar War, and had his powers altered when he and the Vision failed to prevent the Shi'ar Nega-Bomb from detonating.

[37] When Avengers West Coast (renamed) disbands after a dispute, Wonder Man becomes a founding member of its successor group Force Works, but is disintegrated in an explosion during their first mission against the alien Kree.

[40] Wonder Man becomes romantically involved with the Scarlet Witch, but ends their affair during the Kang Dynasty saga, due to her residual feelings for the Vision.

Due to charges of misappropriation of funds in his non-profit organization, Wonder Man is pressured to work for the pro-registration side in the ensuing Civil War drama.

In addition to capturing renegade vigilantes and criminals, Wonder Man is instrumental in creating televised messages to educate the public and yet-unregistered superhumans about the specifics of the Registration Act.

[44] Following the events of the Secret Invasion, Norman Osborn created a new team of Avengers, effectively retiring Wonder Man during the Dark Reign storyline.

Wonder Man later appears on television, lamenting his tenure as an Avenger, claiming it was all a waste of time, and that using violence to uphold justice has caused nothing but heartache and death.

[46] Wonder Man has been seen alongside his old West Coast Avengers teammates Ronin, Mockingbird, Tigra and War Machine in battle with a new version of Ultimo.

[48] After learning that Rogers had disregarded his advice, Wonder Man attacks the new team causing some damage to their base before inexplicably disappearing.

Significantly, Iron Man notes that Simon is 'leaking' ionic energy, suggesting that his current mental condition may relate to his powers rather than being simply a matter of choice.

During conversations with Jan and Sunfire, he makes it clear has no intentions of fighting, and only wants to help use his PR skills to win over skeptical citizens.

[61] During the "Secret Empire" storyline, Wonder Man appears as a member of the Underground which is a resistance movement against Hydra ever since they took over the United States.

Zemo's treatments also granted Wonder Man virtual invulnerability, immortality, enhanced physicality likened to greater stamina, agility, speed, and instantaneous reflexes.

[67] When the Scarlet Witch resurrected him during Kurt Busiek's tenure as head writer, Wonder Man was able to transform into a state of pure ionic energy at will and back again.

[73] Other abilities begotten from manipulating his own ion energies include: emitting force or flame beams from his hands and eyes.

[75] He could potentially even give superpowers to non-powered individuals by imparting his ionic force onto them and can just as easily reabsorb it back into himself as this somewhat weakens his superhuman abilities.

He has done so several times in recent appearances; once being when he was detained by the Avengers after staging an attack on the mansion,[79] and again while battling and easily winning against the Red Hulk.

[80] Wonder Man has some limited effect on Electromagnetic phenomena as was explained to him by Hank and Nadia Pym, to that end he can absorb various forms of energy be it radiological,[81] ionic,[82] even anti-material in nature.

Following Black Skull's defeat, Ant-Man joins Robbie Reyes and his Deathlok companion in their quest to liberate the enslaved Earths from the Multiversal Masters of Evil as he leaves Wonder Man and Infinity Thing to rebuild Earth-818.

[97] In an alternate future, Wonder Man - now with snow white hair and using the alias "Hollywood" - reluctantly aids the Guardians of the Galaxy.

[volume & issue needed] In the MC2 Universe, Wonder Man is never revived after initially dying to save the Avengers, with robotic copies being utilized instead.
