Warning: This is going to be a long post as it covers the comics and the MCU.
People may come out of the woodworks and claim Xavier/Riri is "forced," "strange," or "came out of nowhere," but I think that's a sign they:
A) just want something negative to say to an otherwise healthy, trope-subverting, and complementary black love.
B) likely haven't read Ironheart's comics.
Xavier and his dynamic with Riri (friendship first with romantic seedlings) is not new.
Xavier is a person vital to Riri's world, wellbeing, and character development. He is one of Riri's very few grounding agents. He helps explore, deconstruct, heal, challenge, balance, and build Riri the individual (black Chicagoan teenaged girl), rather than "Riri the super genius superhero" or "Riri the arrogant troublemaker."
As Eve Ewing (writer of Ironheart Volume 1) wrote:
“Riri has always had trouble with friendship. As a young kid she was pushed ahead in school really quickly, she's sort of weird and has trouble with social cues, she's really awkward, and has often felt alienated from other people her age because her life has been so different from theirs. And, of course, she lost her best friend [Natalie] in a brutal, traumatic way.
Xavier is there to provide some regular-person perspective—not as a Super Hero, but as someone who is from where she's from, who is caring and who has her back and helps keep her grounded. And he challenges her to do something that doesn't come easily to her: building and nurturing a friendship.”
Xavier and Riri's dynamic is comfortable and close already because, besides Natalie, Xavier is Riri's closest friend.
Xavier had known and lived by her since they were little kids. So, of course, the show would convey the two have familiarity.
Xavier has already been lightly teased to have a special, possibly love-line like connection with Riri.
Xavier's first appearance is greeting an awkward Riri back at home. Ironman reveals she writes about him in her diary and that Xavier had "taken notice of her." Ironman calls this "promising" and starts to vet him out.
The obvious setup is obvious.
Xavier comes to know that Riri needs people in her corner. From then on, he sets out to remedy this. Two examples are in Ironheart volume 1, issue 3. Xavier points out that the Champions should be there to help Riri rather than plain him and he reminds her that Ronnie is doing what a loving mother does.
In Ironheart volume 1, it's set up that Riri is hard to get through to. She is closed off, still grieving Gary and Natalie, and feels as though people truly don't see her.
Right after this, the person who wakes Riri up is Xavier.
Xavier is the forming answer to this lack Riri has. Xavier sees her.
Riri is complicated, defensive, guarded, emotionally constipated, and rough around the edges. Riri is not an easy person to break through to. Many have tried, only few succeed.
Xavier was able to get through the iron-clad armor Riri wore because of how much they related. Xavier helped jumpstart Riri's character development.
Riri pushes people away. Riri does not really reach out to you, you have to reach out to her.
On the other hand, Xavier is the loyal, kind, and caring type who hangs on and pursues contact. Xavier is rather down-to-earth and with emotional maturity; a stark contrast to a more neurotic, wound-up, and emotional wreck Riri.
In other, more simpler words, Xavier is the golden retriever to Riri's black cat.
Xavier and Riri always related and connected.
Ironheart volume 1, they talked late through the night because of it. They have a fun banter. Riri gets to be what she is: a kid.
Just as Xavier supports Riri in her endeavors when no one else is, and vice versa.
"Iconic." Ring a bell?
At the same time, Xavier doesn't leave Riri at her facade. He tries to get to the real heart of Ironheart.
Riri here adorably repeats what Xavier said to her, even when he was off the phone already. She was trying to get herself acclimated to something now so foreign to her: a friend.
She now has someone who isn't just for a today interaction. She has someone who wants to and will be around.
Xavier understands Riri. He knows her complexities, her language.
That is a fact Riri even knows. She figures she doesn't need to say what she means to Xavier.
He'll get it.
Because he gets her.
When things weigh heavy on Riri, and she can't see her way through it, the person Riri can't help but go to is Xavier.
Xavier is a connection and steady presence Riri needs. He simultaneously is an emotional laxative and challenges Riri. He has her confront what she needs to confront, think about what she needs to think about. Even if it is uncomfortable.
Xavier can also disagree but still hears Riri and is unconditionally there for her. He constantly asks if Riri needs anything of him since his first appearance. He cares about her, even putting himself on the line or giving up so much of his time-energy to help her and those she loves in any way possible (e.g., he helped clean her wounds, fight zombies, detective work, him staying over to not leave Ronnie alone then getting up to defend her despite his own fear, and so on).
In the beginning of Ironheart's first run, Riri is flying a kite with Gary and Natalie (two very important, close, and beloved figures in her life). In the end, Riri flies the kite with Daija and Xavier.
Xavier became one of the figures Riri holds dearly to herself. Riri is healing, and Xavier is apart of that.

All of what I went over has been translated to the 2025 Ironheart show. They didn't randomly conjure Xavier and his relationship with Riri. Every aspect of their relationship is in the blueprint; it's at the heart of Riri's story. The comics are your answer to practically everything you observe in the series.
Xavier is so "regular" instead of another superhero or famous guy
That's the point. Xavier is a foil character.
Riri's main problem is self v self. She needs to unpack her damage. The problem is that Riri actively suppresses and neglects that side of her.
Riri doesn't want to feel her hurt → she shuts down.
Riri doesn't want to be small → she inflates herself to be big – maybe too big for herself to handle.
Active, loving figures stemming from her childhood, coming from the same place she came from (e.g., Xavier and Ronnie - we can add Natalie/N.A.T.A.L.I.E. too), address this. They nurture her bruised humanity. They provide her with normalcy, a home, anchoring, and fulfill all the shades of love (respectively). They embrace the parts of her she otherwise doesn't let show.
It's why Xavier and Riri specially speak in lax, blerd code to one another.
Their shared interests was one of the things that allowed them to bond. Yes, it will be conveyed and a notable staple to their dynamic.
Xavier had always repeatedly been the first person Riri calls for help. It's why Riri expected – anticipated – him in episode 5.
There is a reason why Riri contacts him to help her out of an awkward situation in episode 1. They wanted to organically introduce their dynamic from the get-go.
It is in the comics. Xavier became a trusted someone Riri would fall back on and call. For good reason: he would always show up.
It's why Xavier and Riri are so close.
Riri's hackles are the least raised with him because he knows how to defuse her. They have an unspoken language because they know each other. Xavier and Riri carry this understanding and generally open line with one another. It's why Xavier has "Riri is hiding something" or "Riri did something" senses. It's why Xavier said he thought out of everyone, she'd understand him. We see Xavier constantly and consistently support Riri. Riri also reciprocates, spending some of her first paycheck to get him new headphones so he can work more effectively.
It's why there was a point to convey Xavier frequents her home ("Go home Roger").
That wasn't a random detail slapped in by the series. Xavier canonically comes over where Riri is and hangs out. He visits her home. He does not do that to be annoying (he says how he could leave the moment he thinks Riri seriously wants him gone in Invincible Ironman). He also does that because Riri is the kind of person who is hard to catch and would lock herself away, throwing away the key.
Hence his, "I'm glad I caught you."
It's why we see Xavier being emotionally sensitive and empathetic with Riri.
Xavier purposefully, gingerly, guides Riri to confront her grief and gives her tools to grieve properly. And he could do that, because he loved and lost Natalie, too.
It's why Xavier was the one to effectively answer Riri's question of if she was a "good" person, with a phrase that mirrored her own description of herself (but more positively. Riri called herself a complicated creature while Xavier calls her a complex person).
I must stress this: Xavier is like Riri. It isn't just with (now) losing Natalie, but he too has some awkwardness. He has genius, ingenuity, and ambition he is not quite supported (or as understood) in. He comes from the same streets and experienced brutality (being a victim himself in Ironman (2024) issue 5, which Riri rescues him from).
So no, he doesn't just sympathize or feels pity for Riri like she's his charity case. He empathizes.
It's why Riri acts awkward, shy, or tentative with Xavier, at times in the series.
Not only is Riri socially awkward and reserved to begin with, but she always had her .exe crash with Xavier. She starts lamely saying "uh" or not knowing what to do with herself.
It's why, besides Ronnie, Riri gives Xavier the protection watch, with him being included in, "the people I love" line.
The only difference is that Xavier's surname is no longer "King" but "Washington," as they made him the younger brother of Natalie. A choice I did not see coming, but it only ironically strengthens his tether to Riri and the later trio of Natalie, Riri, and Xavier. It gave Xa and Ri another something to relate to each other, and specifically each other, about.
Another thing: it unlocks higher stakes and a new storyline.
With All That Being Said
Xavier is an important, cemented supporting character of Ironheart. He is a refreshing change of pace, too! Normally, the guy is the focal point and allowed to be heavily flawed or zany, while the girl nurtures and is acting as a love interest.
Ironheart flips this right on its head. Riri is the lead firecracker, Xavier is the accompanying cooling balm.
I don't care if someone doesn't care for him or "ship" them for whatever. That is their prerogative. You can just prefer them platonically (after all, that's the foundation of their relationship: they are friends first before anything.).
But to dismiss, twist, and invent problems to hate him or his connection with Riri (yet ironically graft his characteristics into other characters for Riri shipping... 😭) all because you hate he is a guy and an apparent love interest is odd. The vitriol directed to him is mad weird and immature in my eyes, to say the least.
