Ohh, I like to think about Killer's hair length being the same as princess bubblegum from AT, in those episodes where she has the long hair and the classic dress
Had to look it up, but I can definitely see him having a tendency to lean towards longer hair.
I also have a headcanon that a human or humanized Color would have had hair as long as Jinx’s from Arcane, when her hair was let down and let out of its braids, in the Void.
Two decades without the means to cut it or take care of it means it grew extremely long—probably also thinned considerably due to the lack of upkeep, toxic amounts of stress, and lack of sunlight—likely grew very dirty and tangled, knotted and excessively frizzy and probably even heavy.
His neck still aches under the imaginary weight of it sometimes, and the feeling of hair brushing against his elbows and especially his waist or knees is massively triggering. He’d carry a comb around a lot, just in case, whenever he worries about it.
Because his scalp still burns from the phantom aches of when he tried to obsessively run his fingers through his hair and detangle it, often getting so frustrated and stressed he ended ripping out chunks of hair.
