Character Lore 1: King Boo
As the name implies, he is the ruleer of the boos. He has been king since nearly the beginning of life. He does not rule over a land or a kingdom in particular but strives to take over Woodland first then the Koopa Kingdom before conquering the world.
Creation
Before he became the king of the boos, he was known as Booma, the other brother of both Hooma and Gooma. Also known as the spectral dragon or the Destroyer, he was once following Booma's pack until his questionable actions led him to be banished from the pack. In addition, all his scales were taken away by the other dragons to prevent Booma of messing with life. Though, little did they know Booma was cleverer than they thought. The spectral dragon hid one scale from the others and "left". He followed the pack from afar until the dragons found a planet to establish life. Once all the dragons went to slumber, Booma observed the planet. He recognized the signature trait of each dragon in each race. He knew which life form Hooma created. The spectral dragon wanted revenge on his brother but he only had one scale. With the only scale he had, he used it to give up on his title of god and turn himself into an immortal specter today known as King Boo.
Era of Humans
In addition of making himself immortal, King Boo retained certain powers of his former life, the most important one being to corrupt the souls of fallen people. He could become invisible and spy on everyone he saw. He did not hesitate to cause trouble and mischief but no one could see him. When certain people passed away, King Boo went to their bodies and extracted the out of them to corrupt them and turn them into boos. These boos would also be able to turn more souls into other boos. King Boo's army grew larger by the day and, once his population reached a peak, passed to the act. He revealed himself with his army to the people of the Mainland and took over it. He did not care for the seven lands or the Koopa Kingdom though. He wanted to take revenge by destroying what Hooma, the one responsible for banishing him and taking away his scales, created. He rounded up all the humans in a corner of the Mushroom Kingdom, ready to wipe out all of mankind. The unexpected however happened when the piece of land the humans were standing on ruptured itself from the Mainland and drifted away from it. The king of boos was infuriated but joyed at the same time. He wanted to deal with mankind himself but letting them starve to death would be much more satisfying for him than a quick demise. He suspected that more humans were hiding from him in the Mainland and sent boos all around the continent to find them. He even went as far as corrupting people from the seven lands if they did not obey him.
Era of Drakoopas
When the world reached year 1, a quick turn of event happened. One day, King Boo still had control of the Mainland but, the next day, a new race known as the drakoopas took over and banished him and his boos. Those new people had the power to fight the boos consistently unlike any other races. It infuriated King Boo but what infuriated him even more was that, regardless how sneaky he was to get souls, the drakoopas would always be a step ahead and foil his plan. He would have to get rid of the drakoopas first before going back to erase mankind. The king had enough but got an idea. He studied the drakoopas and posed as different members of each family to stir up trouble among the drakoopas. Since necreans could recognize him in his disguises, he did not bother to go in the Koopa Kingdom. The success of his plan was what started the Dragon War. Afterward, he waited patiently and observed as the drakoopas wiped themselves out.
Until Present
Once all the drakoopas were gone, he waited a bit longer because anarchy struck the Koopa Kingdom. He did not forget his plan to wipe out mankind but he was so glad to have defeated a race more powerful than him and he wanted to mess with the koopas. A few years later, he posed as a necrean and took over the Koopa Kingdom. He ruled over many years until Bowser showed up. He fled the scene before the necrean could capture him. During the Smith War, King Boo tried to make a deal with Smithy but failed as the otherworldly being thought lowly of the boo. King Boo tried to capture Mario once after the Smith War but was stopped by his little brother Luigi.
Today, he resides in an abandoned mansion in the middle of Woodland with the few remaining boos. He still has the power to create more of them but, with the Amariocan population having access to technology deemed life-threatening to the boos, he cannot risk another attempt to take over Amarioca.
Appearance
King Boo does not differ much from the other boos. He is only slightly bigger than his subjects. Another was to distinguish him from the others is that he wears a crown. This is his way to defend himself by fooling his enemies since he is identical to the other boos.
Personnality
King Boo is shown to be very envious, his reason why he hates the drakoopas. He is also vengeful and seeks to wipe out mankind for what Hooma did to him when King Boo used to be Booma and the drakoopas for almost wiping out his race. He has very racist opinions toward anything that is not his race. He considers the people of the seven lands as a joke while speaking of mankind's extinction joyfully. He is a very malicious and mischievous being as he would not hesitate to mess with others. He also has a big mouth and will always ramble on how he used to rule over the Mainland until "those pesky spiny turtles" dethroned him. He also has a short fuse and hates to be seen as a joke by the others. When it happens, King Boo always rant on how he would make the others pay for speaking lowly of him and mixes his words with death threats.
