Ghast

A Minecraft mob that's from the nether and flies in the crimson sky's of the nether and shoots you with fireballs when it sees you in their way as they cry and cry and have lost their ghastling babies or some of them were ghastlings and grew up and became depressed, they drop ghast tears to make healing potions almost like the ghast tears were used to heal their baby ghastlings so they could stay alive and not dry up, these ghostly crying mobs will never be happy ever again and will always cry and cry and kill you whenever they see you again.
