## Personality

After regaining his mind Boo swore his loyalty and allegiance to Cha Yeon-woo. Boo was shown to be angry when a group of players came to kill his master to the point of seeing death to not be enough to punish them as he considered his master to be a god. Also, whenever Cha Yeon-Woo give Boo more soul beads to eat in order to become stronger his loyalty to his master deepen and. Boo consider Cha Yeon-Woo to be a generous master for giving him more soul beads.

Later as the story progresses and Boo begins "regaining" his intelligence, his loyalty to Yeon-woo has only increased further and him becoming increasingly fanatical in his loyalty to him that had borderlines on the religious. As seen where he displayed immense sadistic glee at tormenting his master's enemies and later expressed extreme outrage at anyone insulting or getting in Yeon-woo way and has made a point of swearing immense pain and suffering to them for their transgression against their master.

Later in order to further strengthen Boo, Yeon-woo had him devour Leonte to further increase his power, making Boo ecstatic due to having the chance to absorb the power of a low high Ranker.

Boo was shown to be one of the more basic of the Spirit Familiars of Yeon-woo, Having been shown to still more or less retain his original simple speech pattern of broke words despite his growth under Yeon-woo. However despite this, it was indeed noted and observed by Brahm that Boo by the time of the fall of Walpurgisnacht had already obtained the necessary intelligence and consciousness of his former life as a Magician. Having been shown to have regained his knowledge of his prior life and has begun displaying similar magical research interests as Brahm and showcased more sentience than before.

Boo was noted by Shanon, Rebecca and Hanryeong to be a perfectionist when setting up his work space, having been stated by them to have been very bossy and specific when having them build his laboratory and was stated by Shanon to be in fact be very evil and only ever acts polite in front of Yeon-woo.

Boo has also shown to have begun expressing more emotions than before, having been seen to have developed a somewhat antagonistic/childish relationship with Shanon and has showed annoyance with him due to him tattling about his activates and true nature to Yeon-woo which shows his former self as Faust the Philosopher.

As seen during Yeon-woo's battles against Triton, Iron Lion, Necropolis, Devil Army and later All-For-One, Boo himself has begun displaying more of his original personality as Faust, mixed together with his new sense of loyalty to Yeon-woo. This is seen where he takes intense personal pleasure in killing and slaughtering all of Yeon-woo's enemies and sadistically enjoys toying with them first in battle using his magic. As seen from his fight against Doctor Doom, Boo has now become aware of his previous identity as Faust and has already begun regaining his memories and knowledge as him.

## History

### Background

Boo's exact story or even his previous identity prior to his death is unknown, but Boo was once a powerful Witch Doctor Magician and was stated by Brahm, in accordance to his overall abilities, powers and intelligence in magic as a Undead, was once a powerful Ranker who had power comparable and equivalent to the Nine Kings that currently rule over the Tower.

Later it would be revealed that he was originally Faust, the Dispiser of Light/ The Black Alchemist, one of the most powerful Rankers to ever live within the tower and one of its most legendary Magicians.

During his lifetime, Faust was one of the very first Rankers to come to the Tower and soon made his mark in its history as being one of the founders of the *Demonic Studies* Magical Research Field along with De Roy, where he became one of the First Rankers to have made a deal with a High Class Demon, Maphestopheles and became infamous for his use of Dark Magic. Faust would also study Alchemy and from his pact with Maphestopheles, he gained information and knowledge to create a Philosophers Stone and wrote down his finding within the Emerald Tablet, which would remain within his laboratory centuries later.

Upon being given souls to feed off and his growth during Yeon-woo's early days climbing the first few Floors of the Tower, Boo was shown to be one of the most powerful of his minions to assist him in his endeavors and showed to have already been shown to cast powerful large scale spells with little trouble.

Later after seeing Boo's continued growth, Yeon-woo was surprise to learn that Boo's true power was actually equivalent to that of the "Nine King" of the Tower after it was revealed by Brahm that Boo was not "learning" and "gaining" new powers but he was in fact simply "regaining" and "remembering" his original abilities from before he was killed.
