"If you think about it, this guy qualifies as this young character's Weird Uncle, because he's technically siblings or something akin with their parent or ancestor" is such a great trope
A list of arguably Weird Uncles in my fandoms: + Wei Wuxian (JL's mom's shidi) + Eriol Hiiragizawa (Clow's reincarnation (Li) & mitosis with Fujitaka (Sakura)) + Ouryuu Zeno (doubles as the dragons' brother and great-great-etc uncle) + FMA's Father (Hohenheim's cloned body, thus homunculuncle) + Aang (Zuko's great grandfather's homie's reincarnation)
so Sad it didn't come to me in the manga serialization days of fandom because I'm confident I could've made the joke sonewhat popular via livejournal icons
hey Kiri, isn't this list antagonic in some level for the nephew or niece's POV in most examples? yup! that's part of the goodness of the trope! because they're not the Weird Uncle only in the personality sense, but also because the uncle logistics are bound to weird them out if they think about it
I also simplified WWX's uncle levels. he's the boy's uncle first by being the adoptive brother of his mom and maternal uncle, but his soul also was resurrected in the body of one of his paternal uncles, making him a Double Uncle
