ok now for the art that's gonna be a pain to tag. Designs for a lot of Xylos! Ft. Headcanons! In order (though it is obvious), MHO!Flex, SNO!Xylo, SCP!Xylo, OoO!Xylo, OZ!Xylo, and FO!Xylo (more info below drawing bc i wrote a lot)
Most of the xylos are actually average height (with flex being a bit shorter bc he's a teen, and oz being taller bc he's an actor and thus is probably a bit taller bc most actors are conventionally attractive) in this drawing, they just look short bc i hc FO!Xylo to be an absolute giant at like 8 feet tall bc he's a robot. I also hc him to be AroAce Agender bc he's a robot in the apocalypse, i don't think he even knows what gender and sexuality are. Also OoO!Xylo gets a tail and big ears bc i said so. Flex is A-posing bc i drew him before i decided to start posing them and then just, couldn't be bothered to re-draw him, so i didn't. This drawing is in my more sketchy style, where the sketch and lineart are one and the same with no clean-up before coloring, i use this style for a lot of my drawings where i'm just designing characters so i'm not focusing on getting details perfect and instead am focusing on getting the designs to work
