Top Five of your Personal Favorite Head Canons! Can be for Kon or DC or whatever else you like.
omg i forgot i still have a couple of these to answer from the other day!!! sorry for the delay, instead of brain i only have swiss cheese
sexually fluid kryptonians!! kinda inspired by the left hand of darkness and also the blue-banded goby (a species of fish that can undergo sex changes many times over their lifetimes), in combo with the way new krypton establishes that there isn't really much sexism to speak of in kryptonian society (the main problem is classism). like, i know geoff johns wasn't trying to imply that kryptonians don't have the same binary concepts of sex as humans do, but. My City Now. theyre sexually fluid and have a lot more variation in combinations of secondary sex characteristics than humans do + much less visible sexual dimorphism. BOOM. lets get funky with it B)
kon has a lot of scarring after his death and resurrection. he got preeeetty brutalized - he was impaled in several places and his right hand and left foot torn off, and his right eye looked pretty fucked up too! lets give him lots of scars where the regeneration matrix had to reattach his hand and foot and also where he got impaled. and some vision problems.
kon gets very into fibercrafts after moving in with ma and pa kent! he doesn't expect to, but it turns out to be really good ttk practice, plus he can be helpful by letting ma rest while he mends pa's torn old jeans, and also maybe he likes it when she pats him on the head and praises his neat rows of stitches. he particularly gets into making bobbin lace with ttk, and sometimes sells lil lace bookmarks and doilies at the farmers markets alongside all their produce!
along with kon's glasses and some of his clothes, tim took one of kon's tiny, half-finished (now never-to-be-finished) lace projects, carefully sealed the edges, and sewed it into the inside of the oyl costume, just over his heart. he left it there when he left the oyl costume behind; he was spiraling and felt he didn't deserve to wear it anymore, and didn't want to taint it with his exploits in the red robin suit.
kon's hair is Like That in early tt03 bc the night before he started at smallville high, he got really in his head about having a secret identity tied to superman's secret identity and what if he blew it and what if he got superman's family killed and [further catastrophizing], until he had a certified Teenager Moment and hacked off his curls because that way he'd look less like superboy. ma neatened it into something manageable but it was bad. it was so bad. he started growing his hair out again normally after that initial cut. it was a Giant Rapunzel Mane when he came out of the resurrection matrix, but because he'd just been lying on it the whole time it was also pretty tangled and matted, and he had shit to do (i.e. a fight to win), so he just sheared most of it off to shoulder-ish length with a blast of heat vision and zoomed off, and worried about getting an actual neat haircut again later.
