Royal Guard Slime

Royal Guard Slimes are a variety of slime summoned by the King Slime (and only the King Slime, no other slime bosses) upon defeat. They are a stronger version of the Slime Mercenary and appear to be a humanoid being (double height and length though, as to make them more intimidating) wearing a suit of darkly colored armor and holding long swords, with the same color scheme as the armor. Two will be spawned when the King Slime is killed, and the number of the RGS's spawned shall be two (Monty Python reference. Comment if you get it.). They have different armor designs helmet-wise (one helmet looks like a viking helmet, the other kind of looks like the helmet of Sauron from Lord of the Rings.).
