Adam Warlock: Marvel’s Golden God of the Galaxy
Likely Debut: Guardians of the Galaxy Vol. 3
Adam Warlock’s debut in the MCU has been teased since that very intriguing post-credit scene inGuardians of the Galaxy Vol. 2, but it looks like Warlock will be unleashed in the Guardians’ next adventure.
MCU fans were recently over-joyed to hear thatWill Poulterwill be portraying Warlock inGuardians of the Galaxy Vol. 3and given the character’s power and story potential from the comics, Warlock could be a game-changing force for the MCU’s future.

She-Hulk: A Not-So Hulking Hulk

Soon after Moon Knight joins the MCU, fans will be on the lookout for Jennifer Walters/She-Hulk (Tatiana Maslany) to make her debut in her upcoming tv series.
Although She-Hulk isn’t as massive or mean as Bruce Banner’s (Mark Ruffalo) Hulk, she’s able to retain her emotional control and intelligence while still being a lean and swift fighter making her the perfect foil to Bruce. The potential for a modern MCU Hulk film is greater than ever with She-Hulk’s upcoming introduction.

Blade: Marvel’s Vampire Hunter
Although we know thatMahershala Aliwill play Blade in an upcoming solo film, which recently got a director inTassam Bariq, recent rumors have said that we could see him sooner.

Fans with good ears heard Ali’s voice talking to Dane Whitman (Kit Harrington) inEternals’ second post-credit scene, as confirmed by directorChloe Zhao, and now rumors are pointing to both having a surprise appearance inMoon Knight. It would certainly be a moment that fans would love and makes sense given how closely tied the two characters are in the comics.
Ironheart – The Next Iron Hero
Likely Debut: Black Panther: Wakanda Forever
One of the most highly anticipated aspects of the nextBlack Panthermovie is the debut of Riri Williams (Dominique Thorne) as she becomes the hero Ironheart.
It’s unclear how Riri will exactly fit intoWakanda Forever’s story, but she will likely get her suit fromShuri (Letitia Wright), one of MCU’s best non-super powered heroes, and perhaps we could see her in action before she leads the upcomingIronheart.
Ghost Rider: The Spirit of Vengeance Rides Again
Of all the characters rumored to appear inMultiverse of Madness, the rumors surrounding the possible debut of Ghost Rider have been the most enticing and realistic.
RELATED:Gabriel Luna Reveals What Happened to the Ghost Rider Spinoff
With the MCU aligning more with darker, horror-centric heroes recently, Ghost Rider’s introduction would fit right in, but the big question is: who is it? Will the rumors ofNorman Reeduspossibly portraying Ghost Rider be true? WillGabriel Luna’s Ghost Rider fromAgents of SHIELDbe re-introduced? It’s a genuine toss-up, but the Spirit of Vengeance will ride again in the MCU…eventually.
Nova: An Intergalactic Crime Fighter
Based on the way that the Marvel cosmos is being expanded in the MCU, the introduction of the Nova Corps’ super-powered leader Nova must be imminent.
Kevin Feigehas expressed interest in bringing the character into the MCU and with Nova Corps already being introduced in the first Guardians movie, it’s very possible that Nova could debut inGuardians of the Galaxy Vol. 3, especially with the ever-expanding cast of Vol. 3.
