Have you ever watched anime? They have naturally pink, blue, green, even gradient hair. Look at picrel, this is a 12 year old boy. He's 7' tall and 300lbs at 8% body fat. 14' feet tall if you include his hair. He can touch a cup of water and it will begin producing infinite water.
There's another anime about pirates who live on boats but they magically don't know how to swim. Yet another a man dies and comes back to life as a vending machine and gets his ass kicked by goblins until a 6 year old who is also the strongest person in the world picks him up, takes him into town, then falls in love with him. Anime is wacky and it goes way beyond some bpd goth chick dying her hair.
