- Advice and Trust: Asuka liked Shinji, Rei cared for Shinji, and all of his female classmates had a huge crush on Shinji... and Shinji was completely clueless about it. He never ever noticed. It changed over the story, though. He accidentally got a hint Asuka was throwing herself at him and they got together... which eventually led to Rei spending more time with them AND all of their classmates deciding to chase him actively, much to his surprise and disbelief.
- The grown-up and ponified Godzilla Jr. seems to be flirting with this trope in once he ended up in Equestria during the crossover story The Bridge. In his new unicorn form, he's no Prince Blueblood but has a degree of Tall, Dark, and Handsome to him by some mares' standards. Despite his Gentle Giant persona, he's lived his life so far without even giving romance a thought. When a guard named Blade Dancer starts flirting with him, he has no idea what she is doing and is somewhat creeped out. This is taken to its logical conclusion when Godzilla Junior gets plopped into the middle of the Mermare capital, where he is the only male for miles. Naturally, just about every mermare (with the exception of his escort) wants a piece of him and aren't afraid to let him know. Even the queen of the mermares is interested! However, given this is Godzilla, he doesn't understand their strange behavior around him and unintentionally manages to cause much accidental humor in the process. Somewhat downplayed however, in that he's gotten better at understanding the idea of romance, he's just still not very good at picking up romantically oriented cues. Also, the queen is at least aware of his interest in another and doesn't want to interfere, although she's not against trying to woo him if his interest changes...
- Between books 1 and 2 of the Broken Bow series, Armani Dove attracts the attention of several wood nymphs due to his connection with Artemis.
- Children of an Elder God: Shinji is a really thick and oblivious chick magnet. In a scene, he's watching Rei trying to talk Asuka into sharing him... and he thinks that they can't possibly want a threesome with him.Asuka: And I'm not sharing my boyfriend with you!
Touji: Damn, Shinji, a lot of guys would kill for a deal like that,
Shinji: I'm sure they weren't actually talking about sharing me.
Rei: We were.
- Le Commencement du Diable Blanc revolves around the formative years of Gambit whose smile is already a weapon of mass seduction. Unfortunately for his young admirers, his eleven-year-old self is firmly stuck in the Girls Have Cooties mindset and females swooning and blushing in front of him comforts him in the assumption that the fair sex is inherently crazy.
- Fate/Black Dawn: While Shirou is finally aware that he tends to attract women in the general sense, he is still absolutely terrible about recognizing when it is actually happening. Morgan comes within a heartbeat of dragging him into her bed (hell, when he was first summoned he found herself in her bed), and he never notices until she just flat-out does it. Even then, it takes him a while to realize she is falling in love with him rather than just using him.
- Clueless Dude Magnet example in Hetalia: Axis Powers fanfic Gankona, Unnachgiebig, Unità. Italy has no idea that Germany, Japan, and Prussia are attracted to him. Or so it seems...
- Hero Academia D×D: Izuku (much to his astonishment) is attracting pretty girls like honey attracts flies. As of Chapter 19, no less than ten girls have clear crushes (or more) on him, and he's bound to get even more attention as time passes. Ddraig tells him it's because he's more attractive than other males due to both the Boosted Gear and being part dragon.
- In Incarnation of Legends, Bell is this despite his Harem Seeker and Rescue Romance goals. Due to his Country Mouse naivete, he never recognizes the effect he has the opposite sex with his pure-hearted Nice Guy and Always Save the Girl attitude. Even when the Valkyries are metaphorically and literally trying to seduce him into joining them, he can't even conceive the idea of dating them all at once because he respects them too much. Lampshaded by Kojiro when Bell turns Nyx into a blushing mess.Kojiro: Wooing divinity? So young, yet so ambitious. [chuckles and scratches his chin]
Bell: [frantically waving his arms with a Luminescent Blush on his face] I-I was just being nice!
Kojiro: I know that. That only makes your potential so much more terrifying. [shakes his head with an overly dramatic sigh]
Bell: What are you talking about?!
- Izuku Midoriya is this in My Huntsman Academia. Due to spending the last thirteen years of his life as a laughingstock among his peers for wanting to become a Huntsman despite being a Moon Child, he's become thoroughly convinced that no girl on Remnant would ever want to date him. Because of this, he's utterly oblivious to the fact that his warm and understanding personality is winning him the affections of the many gorgeous girls around him, including Weiss, Pyrrha, Yang, and Blake. In the latter case, he even encourages Blake to ask out a guy she describes as "good", "kind and just", and "a stand up person", assuring her that this guy would definitely say yes if a pretty girl like her asked him out on a date. Meanwhile, Blake is wondering if the gods are trying to make her die of embarrassment with his cluelessness. His belief is further reinforced by the fact that he's considered "plain-looking" compared this more typically Bishōnen peers like Ren and Shouto. This is in spite of the fact that Izuku is lean and muscular with six-pack abs that happen to be mesmerizing for his female friends to look at.
- Shinji in Neon Genesis Evangelion: Genocide doesn't get that he is amongst the popular boys of his class because he has quite the "cute factor" with the girls, being Tall, Dark, and Handsome as well as having Innocent Blue Eyes. His old subconscious belief that everyone hates him still makes him paranoid.
- The One I Love Is...: Shinji drew women wherever he went... and he had absolutely no idea about it. He was genuinely shocked and surprised when Rei gave him chocolates and when Hikari told him that Asuka was in love with him because he was completely oblivious to their feelings and to the hints Asuka constantly dropped.
- A side story of Pokémon Reset Bloodlines establishes that even when he was a kid, Ash was very popular with girls, but never noticed their affection. In the present time, he still remains this way to a degree, since he's unaware that his female companions all harbor a degree of attraction towards him. However, after the Sabrina arc, this is no longer in effect with Ash no longer being clueless and expressing interest.
- Roxas in A Song of Fire, Ice, and Hearts fails to understand that his good looks and heroic behavior have made him very attractive in the eyes of almost any woman (and some men) he meets, chief among these admirers being Sansa Stark and Myrcella Baratheon.
- A running gag in Sunny, Moonie, Twily is the existence of a support group for stallions and mares unwittingly rejected by Twilight Sparkle. Apparently, she takes all flirting literally, and nobody has ever successfully managed to ask her out before she mistakenly assumes they're there for her Lovable Sex Maniac roommate. The one pony that was going to ask her directly was preemptively recruited into the group on the assumption that he would have been rejected, much to his frustration. And then it turns out there's another group for those unwittingly rejected by Sunset Shimmer...

- White Sheep (RWBY):
- Due to his earnest nature and habit of giving girls honest compliments on their looks, Jaune gets a lot of girls interested in him. He never notices them, partly because he grew up without any girls around but his sisters, who gave him a rather skewed definition of normal. Ruby, Velvet, Pyrrha, Blake (sort of), Emerald (a little), and Neo (a lot) all end up with crushes on him that he remains completely oblivious to. Ironically, he mistakenly believes that Yang is interested in him due to taking her promise of "it's a date!" literally. His behavior on these "dates" is so charming that she ends up falling for him despite her best efforts.Yang's brow twitched, and she vaguely remembered Summer once warning her about boys who made her heart race without meaning to. Those were the ones you needed to watch out for, or so Summer had said. They were dangerous, and could make you think dangerous things without meaning to.
- Ren not only has Nora (his Childhood Friend who Cannot Spit It Out) crushing on him, but also slightly Blake, definitely Jaune's sister Lavender, and even High Leader Sienna Khan of the White Fang. At the end of the story, Jaune comments that he's glad he's not in Ren's situation, with multiple girls chasing after him. Weiss smacks him upside the head.
