Nightmare observed the contents of his crafted dream, he was negligent in adding the King of Boos to his little takeover project for the sake of keeping his profile low from the others that know Luigi. If he survived all those world-ending events in one piece, then he must have had incredible help other than that brother of his.

But what puzzled him more is how he even survived the first night, that fool at most can only follow instructions and requests. Nothing more!

He paced around in his warehouse, now becoming more and more like a camouflage mansion since it's been his base of operation for a while.

He debates whether he should add Boo to the list or simply let him stay within the confines of that old professor's container.

He thought for a bit until a fatal realization hit him. That professor would most likely convince Boo to fight him with Luigi. He remembers how possessive Boo is from Luigi's memories, what are the chances that he won't come after him too for simply laying hands on his living rival.

He made his decision, he will capture the King of Boos. He will be made a fine tool like the first two that he hijacked.

And so he dissolved into mist and traveled to the professor's lab.

King Boo floats in a circular path within the confines of his transparent containment for an immeasurable time, feeling incredibly frustrated that some other being is capable of doing what he can't do. Successfully defeating Luigi while in his best shape.

He began analyzing the wounds that Luigi received on the day when he first encountered that creature, he remembers deep claw marks on his thighs and thrashed wounds on his head. Did the creature first slow him down by wounding his legs and stun him with a strike to his head? Or did it attack Luigi with an ambush attack and lock him in a tight coil like a serpent?

There are so many possibilities that could have happened, so many new ways of attacks that he can use against Luigi in the next fateful time that they will meet.

All of a sudden King Boo paused, why had the lab become so quiet. This place that he calls prison was never quiet, from the constant whirring of the machines to the chattering of the ghosts. It's a small hub of rebounding noises that he had gotten used to for many years, mainly because he lived and ruled over a huge portion of ghosts and boos in the world, such noise has become nothing but background sound for him. It's something he never noticed,

never noticed until now.

He spun around to look at his surroundings, and the first thing he noticed was that everything was pitch black, the only sources of light left were the overhead display that was used to illuminate him like a gallery prize and his own ghostly aura.

He attempted to call out to the other ghosts, to get some sort of sign that he wasn't completely alone. He kept calling and calling.

Eventually, his calls became yells, he needed someone, someone to respond. Even if it's Hellen Gravely or .

Soon he stopped, panting from the effort, his tongue hanging out like a puppy that just finished a long energetic run.

Suddenly a voice spoke, "Seeing you so helpless is quite entertaining I must say."

King Boo immediately turned towards the source of the voice and was startled to see a pair of red ruby eyes fixed on him.

…Was this the same creature that attacked Luigi?

As if reading his mind, the creature responded "Yes, it is I. The one who easily overpowered that green twerp in a few moments which you can't even do for 20 years."

Hearing that, immediately snapped him out of his shock and he replied angrily in a loud voice.

"WHO DO YOU THINK YOU ARE? INSULTING A KING LIKE ME!"

He puffs out his chest in an attempt to show dominance, the eyes did not seem to be impressed.

"I can insult you in any way I want" it replied calmly. "Because I'm going to be your King soon ."

This stumped King Boo for a second, this thing will force him to serve it? The idea was so absurd that it made him cackle with jest, it can't be serious, can it? How could something that refuses to even show its appearance could possibly rule over someone like him?

However, before he finished his laughing fit, he felt a painful shock that shot through his body so abruptly that it made him choke on his own tongue for a moment.

His laughter soon became a coughing fit as he attempted to relieve himself from the momentary shock that he just felt.

"Had enough yet?" it taunted.

King Boo looked up, his face twisted into a snarl as he glared into those ruby-colored eyes.

"You won't ever enslave me!" He sneered.

The eyes narrowed,

"Oh really? Shall we test that theory then?" It replied in a daring tone

King Boo immediately noticed claws coming towards him, centimeters by centimeters, inch by inch.

He pressed against the transparent container in an attempt to get away from it, but to no avail. It draws closer and closer to capture him.

He spun around and urgently bang on the glass container that holds him, desperately trying to break out and escape from the approaching doom.

But alas, he heard a clunk that signifies the claw's grip on his container and snapped it from its holding place, and dragged him into the darkness.

He soon lost consciousness and joined the ones before him who experienced the same fate as he, his soul soon undergo an irreversible transformation that will soon change everything about him and the mind of the one that he is sent to hunt.
