In one of the latest episodes of the CW's BoJack Horseman aired its final season in early 2020.
Unfortunately, asexual characters are few and far between on TV. As it is an underrepresented sexuality in media - albeit it slowly increasing - people have recognized various characters as also being on the asexual spectrum. These characters are considered inspirations as they helped viewers realize their own sexualities.
Spooner - Legends Of Tomorrow
Legends of Tomorrow is one of the best sci-fi shows with LGBTQ+ main characters and in one of the recent episodes, Spooner comes out as asexual. Despite not initially knowing her orientation and blaming it on her encounter with aliens at a young age, Zari 2.0 helps her and explains the definition of asexuality.
Spooner's eyes lit up to know that she wasn't alone in her feelings. And asexual viewers across the world have been rejoicing in the recent representation and applauding the CW for their first asexual Arrowverse character. Fans are already eagerly waiting to see how Spooner's story and identity develop.
Crowley & Aziraphale - Good Omens
Though the main characters of Good Omens creator Neil Gaiman has clarified the characters' genders by stating that they are ethereal and celestial beings that cannot be tied to gender or sexual orientations.
The two characters, whether they are romantically in love or not, have helped others realize their own sexualities. Neil Gaiman himself "wouldn't exclude them as ace, or aromantic" as they are a retired angel and a fallen one. Crowley and Aziraphale do not experience things the same way as humans but that doesn't stop fans from hoping for confirmations of their asexuality, gender-fluidity, and possible relationship in season 2.
Data - Star Trek: The Next Generation
Among others such as Odo, Quark, and Seven of Nine, Star Trek: The Next Generation's Data has also been heralded as an asexual icon. He is an excessive and literal example of asexuality as an android who is incapable of human emotion (until Star Trek Generations), hormones, or sex drive. In spite of the negative connotations if the character were canonically ace, many fans have discovered their own orientations through Brent Spiner's character.
Data was always looking to get closer to humanity and hopefully achieve it himself. Under external forces, he has a sexual relationship with Tasha Yar and seeks to have new experiences in a romantic relationship with Jenna D'Sora. Data's character has unwittingly given a voice to the ace community and has shown what it can be like for asexual people to be in a relationship with those who are allosexual or non-asexual. For this, he remains an icon.
Raphael Santiago - Shadowhunters
A lot of the time asexual characters make one-off appearances, like Florence in Shadowhunters, Raphael Santiago did not disappear after he explained to Isabelle Lightwood that he's "just not interested in sex" and he never has been - even before becoming a vampire.
Despite the flawed execution of asexuality in Shadowhunters - considering Raphael's antagonism and addictive relationships - it has had a positive influence on the ace community. It demonstrated how allosexual/asexual relationships are possible as well as helping viewers feel more seen and understood through the representation in such a popular show.
Daryl Dixon - The Walking Dead
Though Daryl Dixon is also non-canonical, he has been ace-coded by the actor Norman Reedus and the creator of The Walking Dead, Robert Kirkman. The show's writers withheld Reedus' character from having any romantic or sexual relationship with anyone for over nine seasons. While this has annoyed fans who ship Daryl with Carol or even Connie, the character has helped many people understand their own orientations.
Despite the romantic relationship he had with Leah in season 10, many still view the character as romantic asexual since the two have never kissed or been physically intimate at all on-screen. Asexual viewers still hope that, with the final season yet to air and a Daryl/Carol spin-off in the works, it will at some point be made official and help further asexual representation.
The Doctor - Doctor Who
Sexuality and gender can shift throughout a person's lifetime, so when one is capable of regenerating, that fluidity becomes an even greater possibility. Various incarnations of the famous science-fiction doctor, both classic and revived, have helped fans enormously understand their own identities.
Though the Doctor's lack of sexuality began in the classic era as a way to engage children and teenagers, it doesn't stop modern fans from reading the Doctor as ace. Though no two doctors are the same, they all share the same trait of not necessarily seeking out potential relationships. The Doctor proves that life can be exciting, thrilling, and fulfilling without needing romantic or sexual partners.
Sherlock Holmes - Sherlock
There is perhaps no one less interested in romantic or sexual relationships than the great Sherlock Holmes. He is far more interested in solving cases to care about any of that. BBC Sherlock's television predecessors, and even the literary works themselves, show that Sherlock Holmes has no interest in sex with anyone.
Fans may ship him with Irene Adler or John Watson or even Moriarty, but many find a non-sexual solace in the uninterested consulting detective. That is also in spite of Steven Moffat's insensitive comments to The Guardian that if Sherlock was asexual, then there would be no fun or tension in that - as if criminal drama were to disappear because of his lack of sexual desire. Nonetheless, Sherlock Holmes has been considered an asexual icon since the character's inception and has helped people across the world and the ace spectrum.
Caduceus Clay - Critical Role
Caduceus from Critical Role's Campaign Two is an asexual and aromantic firbolg cleric. Taliesin Jaffe decided his character was ace/aro while creating him but wanted it to come up organically. Throughout the campaign, Caduceus alludes to his disinterest in sex and romance until episode 114 where he specifically states that he is "not into anybody."
Caduceus's asexuality was met with much positivity from fans who had been relating to him before the reveal. While it is rare for asexuality to be represented, it is even rarer for aromanticism to be shown in media as a lack of romantic tension is considered dull. Viewers and the ace community alike already consider him an iconic representation.
Castiel - Supernatural
Fans have speculated on Castiel's sexuality from his first appearance in Supernatural in season 4 and whether he would be with Dean. Castiel often had to remind his friends and others that he is a celestial being that does not conform to gender or sexuality the way that humans do. He is capable of emotions and forming attachments but seemingly rarely experiences sexual attraction.
The only occasion that Misha Collins' character has demonstrated this is when he was human and sleeps with April - who unfortunately ends up being a reaper that wants to (and does) kill him. While sexual interest seems little to non-existent, his ability to love is enormous and genuine. Castiel is not just defined by his relationships whether they are platonic, familial, or romantic - he is a brilliant character in his own right. And he has helped many people in the SPN family to learn who they really are.
Spock - Star Trek: The Original Series
Star Trek has been at the forefront of fandom culture since the original show's inception; including pairing and fanfiction. While some have learned more about their orientations due to Kirk and Spock's seemingly more-than-platonic relationship, fans have also been able to identify themselves thanks to the alien character Spock who at times can come across as asexual.
People continue to adore the character and aces often find similarities in themselves and Spock's unmistakable traits: comion, loyalty, and devotion to logic. Moreover, fans find themselves identifying with the Vulcan's logical approach to sex - Pon Farr every seven years - and Spock's personal disinterest in romance, sex, and ionate emotions many years later.
