King Slime

Almost as recognizable as their more basic subjects, King Slimes have been in most of the DQ games. They have a big crown, a chubby face, and are often first encountered when multiple slimes merge into one. They used to be the biggest and baddest of the slimes, but the games have added whole other tiers of slime above them and now almost every commonly used slime has a king version. They're still the only ones who have their crown be an iconic piece of equipment though.
