[PRE-BOX HEADCANONS]
◦LJ was made BY Jason the Toymaker
◦LJ was one of Jason's first creations
◦LJ was eligible to change his physical appearance at will, changing to whatever Isaac wanted him to look like at the time
◦LJ was supposed to be designed to cater, accept, comfort, support, and care. However, he was not supposed to love
◦Jason accidentally gave LJ the ability to love, on top of accidentally giving him the full scale of emotions including anger, sadness, jealousy, and depression
◦LJ grew to love Isaac (who was about 13 while he was just as young) romantically and he was so incredibly hurt when Isaac began ignoring him because he could feel these harmful emotions
◦LJ lost his colors because he was fading away from Isaac's mind
