He appears as the secondary antagonist on the series' three-part premiere Thunder War, on which he takes advantage of the Avengers' disappearance to bring on the Thunderbolts, who (instead of protecting the New York citizens like the Avengers do) work to establish a new order, forbidding the vigilance of other heroes, much to the citizens’ secret displeasure. His plans are then foiled when Spider-Man and his friends manage to bring back the original Avengers, defeat the Thunderbolts and expose Jameson for allowing Kang the Conqueror to abduct the Avengers. Jameson was then taken to jail and stripped of his role of New York Mayor, which is passed to Happy Hogan. He was last shown sharing a prison cell with his former employees (whom he fired after accusing them for "working with Spider-Man") and panicking as his cellmates proceeded to vengefully beat him down.

==== Thunderbolts ====
A group of metahumans (and false heroes) led by Baron Zemo (in the alias of Citizen V) who were assigned to become Earth's new "protectors" after the Avengers are transported to the future. They were defeated and exposed by Spider-Man and his friends as well as the Phoenix Corps, who then exposed Jameson's crimes, brought the Avengers back to the Present and defeated Kang. This version of the Thunderbolts is based on the Squadron Supreme.
* Hyperion / J. Jonah Jameson Jr. (voiced by Wil Wheaton), Jameson's son and the second-in-command of the Thunderbolts with Superhuman Strength, Speed, Stamina, Flight and the ability to shoot Optic Blasts. In "Werefox on the Run", he is one of the three villains (along with Electro and Klaw) who are assigned by Viper to watch over Vanessa Barsi (although it is shown that Hyperion is a reluctant member; as he is shown having an obedience collar designed by Dr. Zola) until her Inhuman powers (and Werefox form) manifests when Rosy Barsi breaks through the facility and releases the Terrigen Fog. He is demanded by Viper to take Vanessa back to her cell without harming her, but only for Vanessa (who is completely transformed into a Werefox like her daughter) to bite his neck, absorbing his strength, stamina and optic blast firing and causing his muscle to expand beyond its limit and his overloaded optic blasts to disintegrate him into ashes.

After the Thunderbolts are exposed and disbanded, she appears in recurring episodes on the moniker of Thundra. In "Werefox on the Run", Thundra is among the villains who have their powers absorbed by Rosy Barsi (in her Werefox form). Rosy absorbs Thundra's strength by biting her shoulder and arm, causing Thundra's muscles to expand beyond their limit (making them too big for Thundra's boots and costume) until she is rendered unconscious and her muscles return to normal. She is later found unconscious (and naked (offscreen)) by Wasp and Tigra.

* Speed Demon / James Sanders (voiced by Jason Spisak), a professional thief and member of the Thunderbolts who developed Superhuman Speed running powers from a Speed Belt of Kang's technology. In "Werefox on the Run", Speed Demon is among the villains who have their powers absorbed by Rosy Barsi (in her Werefox form). Rosy ambushes Speed Demon and absorbs his speed by biting his legs and Speed Belt, causing his belt to speed him up and vibrate his molecules beyond his control and age him to near death, causing him to crumble into dust.

In "Werefox on the Run", Shriek was among the villains who have their powers absorbed by Rosy Barsi (in her Werefox form). Shriek was trying to kill a innocent woman and her children in a alley until Rosy (having absorbed Thundra and Speed Demon's powers) came by and attacked her before biting her neck, absorbing Shriek's sound powers, and dragging her to a nearby Hammer Industries facility, where Shriek's overloaded powers caused her to scream uncontrollably and fall unconscious as her powers destroyed the facility. And because she worked for Hydra, Rosy also took from Shriek a tracker which would lead her to her mother.
** Appearance: The same as in The Amazing Spider-Man #392 and animated after the female characters in Avengers: EMH!. Her Carnage Queen form is based on that of Mary Jane's in the Ultimate Spider-Man vs. the Sinister 6 episode "The Symbiote Saga, Part 3".

== Stan Lee Cameos ==
As in most Marvel movies and TV shows, Stan Lee also makes posthumous cameo appearances in several episodes of Avengers Unleashed. Some cameos are silent and inaudible. Others have dialogues done via archive audio dialogues from previous cameos TV shows, films and video games.
* In "Thunder War, Part 3: Avengers Reassembled", Stan is seen among the angry citizens who proceed to confront J. Jonah Jameson once he is exposed for his true schemes. Just as Jameson vows revenge, Stan appears and shuts him up with a punch in Jameson's face before saying: "You're not gonna be in 'mint condition' after this!" and, while seeing Spider-Man and his friends proceeding to stop Kang the Conqueror and the Thunderbolts, he says: "Good luck, Spider-Man. Excelsior!". Those lines are said via archive footage from Lego Marvel's Avengers and the Ultimate Spider-Man vs. the Sinister 6 episode "The Symbiote Saga, Part 3" respectively.
* In "Sinister Venom", at the moment Peter Parker is preparing his room in the Avengers Tower, he includes several pictures of himself with his friends, family and most memorable Spider-Man fans. Stan Lee appears in two pictures: one with Peter Parker (as Spider-Man), the other with Peter (in his civilian guise) and Mary Jane Watson. At one point, Steve Rogers and Tony Stark (who were inspecting Peter's room) acknowledge these pictures, with Stark replying: "Heroes like the Avengers are among the good guys. But men like this one are among the best guys.".
* In "I'm Only Inhuman", he is among the citizens who admire Ms. Marvel training under Spider-Man's instructions. He is heard saying: "Wow! Nice suit.", on which he admires Kamala's costume design. Those lines are said via archive footage from the online version of the 2017 Deadpool short .
* In "Project Ultimate", he is shown in a store talking to Cindy Moon, who went there to buy a cheerleader uniform for Anya Corazon, while Peter Parker was training Miles Morales. He has two lines: "Smiling Stan Lee at your service." (when Cindy first encounters him in his store) and "It always fits. Eventually." (when Anya asks if her uniform will fit in her). Those lines are said via archive footage from Lego Marvel's Avengers and Spider-Man: Into the Spider-Verse respectively.
* In "Avengers Academy" - Stan Lee is shown watching and listening to Hercules' argument with Captain America and Iron Man from a buiilding. At the moment Hercules accidentally smacks a car nearby, an angered Stan is heard yelling: "Don't make me come down there, you punk!" at Hercules. Those lines are said via archive footage from Spider-Man: Homecoming.
== Soundtrack ==
The soundtrack consists of theme songs from the Avengers films in the Marvel Cinematic Universe and The Avengers: Earth's Mightiest Heroes!. The opening title song is a short reprise from the theme song played in the track "Assemble" in the 2012 film.
== Event Details in the Series ==
While this series is a reboot to The Avengers: Earth's Mightiest Heroes! and Avengers Assemble, the show also features an original story on which the episodes, unlike most of the ones in Avengers: EMH!, are not adaptations to comic book arcs published for Marvel, although some elements in both Marvel and DC Comics are used.
* Aunt May is married to Gwen's father George Stacy, making Peter and Gwen step-cousins.
* Betty Ross (who was General Ross' biological daughter) is reimagined with the surname Lockwood, and is introduced as Ross' adopted daughter instead of biological.
* Ultron is created by Arnim Zola during World War II era instead of Hank Pym or Tony Stark in modern era. The villain becomes depicted as a Dark Lord who was sealed away for decades waiting for revenge on humanity.
* Eddie Brock's grudge with Green Goblin happens after Goblin torments him for one “really bad day”. This moment is a homage to the DC Comics' Batman graphic novels A Death in the Family and The Killing Joke.
* As in Ultimate Spider-Man and the New Avengers and its second alternate story, Felicia Hardy / Black Cat is introduced as a fully heroic character rather than antagonist or anti-hero.
* Also as in Ultimate Spider-Man and the New Avengers and its second alternate story, the Phoenix Force is an entity which is split between its two halves: Light and Dark.
* Typhoid Mary being the Green Goblin's love-obsessed accomplice mirrors Harley Quinn for the Joker in DC Comics.
