Lord Royal Highness (also goes by LRH) is the leader of the lost city of Atlantis. He appears in the episodeAtlantis SquarePantis, as Atlantis' ruler that greetedSpongeBob and the crew. He is usually happy about being the ruler, and has a positive attitude, until SpongeBob and Patrick pop the world's oldest bubble. This infuriates him and he orders the Atlanteans to seize them. He also appears clumsy, because he fell down the stairs to the royal palace. He has had visitors before because he says that people don't usually stay with the tour that long (as long as SpongeBob and Patrick did). When he finds Plankton, "A Talking Speck", as a replacement for the Bubble, he is no longer angry. He is voiced by famous British rock vocalist and musician David Bowie. His skin is blue and his brain is clearly visible. As for his lips they are large and red, his nose is similar to Spongebob's. His hair is orange and his left eye is color green while the other one is blue.
When SpongeBob and Patrick (mostly Patrick) pop the world's oldest living bubble, he sends his army to kill them.
