Ant-Man and the Wasp: Quantumania – 7 Characters William Jackson Harper Could Be Playing

The first trailer for Anti-Man and the Wasp: Quantumania was recently released, and Marvel wasn’t long with even more information with the news that William Jackson Harper is also set to join the MCU in the upcoming Phase Five film. Harper is, of course, best known for his time playing Chidi on The Good Place and Marcus in Love Life. He’s been among the lists of actors fans have been wanting to see in the MCU, and he could work well in several ways, whether a comedic hero or a charismatic and thoughtful villain.

Ant-Man and the Wasp: Quantumania will suck audiences back into the Quantum Realm and give Jonathan Majors his full introduction as Kang the Conqueror after playing He Who Remains (a variant, in Loki). That alone is drawing fans’ attention to Ant-Man and the Wasp: Quantumania, but this news adds to the growing hype and excitement. Many fans already have an idea of who Harper could be playing, but he’d excel as various characters. Given the story and scope of Ant-Man and the Wasp: Quantumania and William Jack Harper’s many talents, here’s who he’d be a good fit for.

Mr. Fantastic (Reed Richards)

In reaction to this news, there’s one major consensus among the fans. Based on the sheer amount of comments, tweets, and posts, most think William Jackson Harper could end up playing Mr. Fantastic in Ant-Man and the Wasp: Quantumania. He was previously portrayed by John Krasinski – in another case of social media fan-casting – in Doctor Strange in the Multiverse of Madness, but since that was the Earth-838 version, some think it was a one-time gig.

Ant-Man and the Wasp: Quantumania is directly linked to Avengers: The Kang Dynasty, but many fans theorize it’s also connected to Fantastic Four as it will introduce Marvel’s First Family. Harper would make for a great Mr. Fantastic as, like Chidi in The Good Place, he can emulate pure intelligence with an awkward nuance, and, in this case, it can be amped up with Reed’s characteristic arrogance. Harper’s Mr. Fantastic is someone many viewers would be very invested in seeing grow and evolve across the future of the MCU – it could be casting on par with Robert Downey Jr. as Iron Man.

Goliath (Tom Foster)

A strong option many should consider is that Harper could be playing Tom Foster (aka Goliath). He is the nephew of Bill Foster, the first Goliath (played by Lawrence Fishburne in Ant-Man and the Wasp). Like his uncle, Tom can grow to immense sizes with all the strength to match, making him a powerful superhero. His inclusion in Ant-Man and the Wasp: Quantumania would make sense, though, given the trailer showing that the film primarily takes place in the Quantum Realm, Tom’s part might be reserved on the tail-ends.

Interestingly, Tom Foster has a bit more of an anti-hero edge than his uncle as he’s fought against the Avengers at times. This was in response to Bill Foster’s death during the first Civil War storyline, after which Tom blamed the Avengers. He would join up with Simon Williams (aka Wonder Man – who, himself, is getting his own Disney+ series, presumably in Phase Six) as part of the Revenger. By introducing Harper here as Tom Foster, they could eventually adapt this conflict later down the line.

Doctor Doom (Victor von Doom)

As the case is strong for Harper to play Mr. Fantastic, so too is the case for his foil and archenemy, Doctor Doom. Now that Kang is here, he is by far the most popular and important Avengers villain missing from the MCU, and many still assume he must play a big role in Avengers: Secret Wars like in the comics. As such, fans are counting down the days till they see him in the MCU – with some theorizing it’ll happen at the end of Black Panther: Wakanda Forever – and in any case, Harper would make for a great Doctor Doom.

Harper could give Doctor Doom a charisma and a personality that is classic MCU (and something lacking from previous portrayals). He’d still be domineering and immensely clever, but there would be a compelling nature that could allow viewers to appreciate the character even more. It would be a surprise to see Doctor Doom in a film where Kang is already starring, but it could be done in a post-credits scene – perhaps the two villains strike up a deal to work together, leading into the Avengers films.

Kang Variant (Nathaniel Richards)

As he played He Who Remains, Jonathan Majors will most likely play other variants of Kang the Conqueror in the MCU, whether actually in Ant-Man and the Wasp: Quantumania or beyond. However, if they do want to go with a different actor for one of them (such as William Jackson Harper since as shown in Loki and Spider-Man: No Way Home) not all variants share the same face. Specifically, Harper could make for a good Scarlet Centurion.

Scarlet Centurion is interesting among the plethora of Kang variants as there are several variations on his story, so there are fun things the MCU could do with him. He once ruled over Ancient Egypt as Rama-Tut, but upon meeting his ancestor, Doctor Doom, he restyled himself as Scarlet Centurion. Another more recent comic – Kang the Conqueror #2 – says Scarlet Centurion was made when a younger Kang was enslaved by Rama-Tut.

A logical way to overstep these complex and confusing origins is just to have Harper play Kang’s son, Marcus Kang aka The Scarlet Centurion. As Ant-Man and the Wasp: Quantumania is at its core about Scott and his relationship with his daughter, Cassie, having Kang and his son feature would add some more depth to that narrative.

Arcturus Rann

The MCU is ripe with opportunities to focus on obscure and deep-cut characters. That’s what Werewolf by Night and She-Hulk: Attorney at Law did, and it worked in spades (so Ant-Man and the Wasp: Quantumania could do the same). As such, William Jackson Harper could be playing one of the Micronauts, and more specifically, Arcturus Rann. The Micronauts is a team of heroes based on a series of toys who operate in the Microverse, and Arcturus Rann is their telepathic leader. They could be the group of people shown finding Scott and Cassie Lang in the Ant-Man and the Wasp: Quantumania trailer.

The big issue with this is the question of rights. According to CBR, Hasbro Studios owns rights to the Micronauts, and, as such, Arcturus Rann (this also applies to Bug who many hoped would be part of the Guardians of the Galaxy). However, Marvel’s dealt with rights issues before with Sony over Spider-Man, and it worked out in the end, so there’s hope it can be done again. Since the Microverse was adapted into the Quantum Realm, the Microverse could also be rebranded too. This would be a fun way for Harper to play someone completely unexpected which could help expand the MCU even more.

Ant-Man (Eric O’Grady)

As with the case of Kang, there might be multiple Ant-Mans in Ant-Man and the Wasp: Quantumania. However, as opposed to variants, it could introduce Scott Lang’s successor, Eric O’Grady (and William Jackson Harper could be a good fit). This is a role quite dissimilar to what Harper is well-regarded for, so it would be a fresh opportunity. Eric O’Grady is the third Ant-Man, and one of the major characters associated with Scott Lang and Hank Pym still missing from the MCU.

O’Grady was a low-level SHIELD agent and a morally dubious man who got his hands on one of Hank Pym’s suits, eventually using it to become the Irredeemable Ant-Man. Based on the film already seems jampacked with characters and storylines, but adding him in here would allow him to feature more predominately in the future.

Quantum Realm Citizen

A very likely possibility, despite all the grand fan-casting, is that William Jackson Harper isn’t playing a major superhero or villain, but rather a prominent supporting character in Ant-Man and the Wasp: Quantumania. This could put him as one of the denizens of the Quantum Realm, whether he’s part of the crew that finds Scott and Cassie, he’s working for Kang, or he lives among the residents in Chronopolis and/or wherever Bill Murray’s character is residing.

He might not have long-lasting implications for the rest of the MCU, but he could still make a big impact on the audiences as a minor character, especially if it’s as comic relief. However, he is someone of prominent and popular notoriety, so many fans are expecting him to play someone of the same standard in the MCU. If that’s the case there might be many disappointed reactions saying they wasted someone talented like William Jackson Harper.
