After Mushroom Kingdom and Koopa Kingdom, we have...
✨The boos and the ghosts✨
1 & 2) King Boo, Hellen Gravely.
King Boo is the king of the Boos and their shepherd, he really wants to help his kind.
Hellen Gravely is also a pastor, but she is one of the ghosts and also King Boo's assistant.
King boo and Hellen are a couple in this AU
-> There is a difference between being a shepherd of boos and of ghosts, King boo doesn't help the ghosts, that is until he starts dating Hellen, now two help both types of ghosts.
-> King Boo is a human being and also Boo at the same time, before he died he was a normal human, after he died he became Boo, he became a "lost soul" but King Brennus saved him, after the former king saved King Boo, he turned into a little Boo, Brennus raised him to be the new king.
Brennus raised King Boo as a son, but I think their relationship is like Granny and Slendrina, they are both piscopaths. Brennus didn't know anything about being a father, he was a little cold towards King boo, after a few years King boo became king and Brennus retired as king.
-> Hellen is a human, she was born as a ghost, her parents were ghosts, when she was born her mother abandoned her and her father. Her father raised her, a few years later he remarried her stepmother, at the time her parents were dating, Helen met her half-sisters, Brittany and Selena, soon she became a great older sister, a year later her last sister to Elena. During her growing up, her father, William Gravely, taught her various spells from several books. When she was a teenager, Helen had an accident, a magic ended up affecting her skin that made her look like the one that appeared in Luigi's mansion 3, she was desperate and went to school with a hood, but someone discovered it and took off her hood and everyone laughed. She cried a lot that day.
Her father discovered that makeup could save her face, he told his daughter "You have a beautiful face" but Hellen thought she was ugly, when she became an adult, she became a shepherdess of ghosts and opened her own hotel to help ghosts.
-> King boo and Hellen met after the events of Luigi's mansion dark moon, King boo ran away from E. Gadd's laboratory and got lost in the forest, Hellen found him and was enchanted because she was his fan, she offered King boo to stay in their hotel, they then came up with a plan to capture Luigi and his friends, in the events of Luigi's mansion 3, they had a romantic atmosphere, right after Luigi's mansion 3, they helped each other escape from E. Gadd's laboratory and then began to to fall in love.
Boos are spirits that have lost souls, when they die they are lost in different places, if they are not protected or guided they are lost.
-> Boos are great helpers, they know how to do different things!
-> It's normal for boos to fall in love with other boos, their sexuality is non-binary and they can be pansexual and polyamory.
-> Because they are lost, the Boos end up becoming shy and afraid of other beings. {This is based on Super Mario Bros 3 where when Mario entered the mansion, the Boos wanted to scare him and then the plumber turns to see them and they look shy and very cute}
-> The role of shepherds is to guide and help their species, when the species is guided by the shepherd, he can become helpers, King boo's duty is to guide them so they don't end up like "lost souls".
4) King Brennus boo/Big Boo
Meet the ancient king of boos, the king Brennus known as Big Boo.
In Yoshi's island, there was an antagonist called Big Boo, when I saw him I thought he was a king, so I had this idea for him.
The idea of making Big Boo is that he is a Boo but he can turn into a big Boo or a small Boo like the others {This is based on Mario Wonder where when they defeat King Boo, he turns into a Boo}
-> Brennus was king of the Boos, at the time that Bowser's parents got married, I can say that he has been king for many years, he was known as "Big Boo" due to the fact that he was taller than most of his species.
However, even though he was king, there was a problem. He needed a successor! It was difficult to find a decent one until one night everything changed...
-> One night Brennus was walking through the forest like he always did, then he found a soul, but it wasn't just any soul, it was King boo! Brennus ran to help the dead king, he was all bleeding and full of marks on his body, that's when he discovered something, King boo had become a "lost soul", Brennus made a room for King boo and went to sleep.
The next day, Brennus and Nurse Boo went to check on King Boo, but when they entered, there was no longer a King there, there was a child, that's when they discovered it was King Boo himself, he had become a half-Boo human.
-> Brennus then saw something different in Boo, he was different from the others, so he made decisions, adopted and decided that King Boo would be the next king, over the years Brennus raised King Boo as a son, but I can say that they have an equal relationship from Granny and Slendrina, taught how to be a shepherd and much more.
After King boo became an adult, he was crowned as the new king and Brennus retired as king, now they both live in the castle.
