(File 20) King Boo – The Ruler of Mischief

SUBJECT DESIGNATION: King Boo – “The Ruler of Mischief”

CLASS: Type V Hierarchical Specter (Cognitive / Leadership Variant)

CONTAINMENT STATUS: Freed from portrait; current location mobile within mansion

THREAT LEVEL: Extreme (Strategic Manipulation / High-Risk Aggression)

IDENTIFICATION

Full Name (During Life): Unknown; spiritual entity self-designates as “King Boo”

Apparent Age: Unknown

Gender: Male-equivalent spectral entity

Post-Mortem Appearance: Large, floating, semi-luminous apparition, distinguished by exaggerated features, glowing crown, and ethereal grin. Exhibits capacity for size alteration, cloaking, and teleportation. Surrounded by lesser Boos, which respond to his commands.

BIOGRAPHICAL RECORD

King Boo is a unique Boo-class entity who claims dominion over all subordinate Boos within the mansion. Charismatic and manipulative, he has demonstrated advanced strategic thought, planning multi-layered traps, and capturing high-value targets, including Luigi and Mario.

It is theorized that this iteration of King Boo may incorporate residual essence from a corporeal being—potentially the soul of Bowser (hereafter referred to as “Dry Bowser”), who perished in lava in prior events from an alternative timeline. This fusion may account for unusually aggressive and revenge-focused behavior, as well as enhanced psychic coordination with subordinate Boos.

Unlike typical Boos, King Boo demonstrates:

Conscious long-term planning

Tactical orchestration of multiple entities

High-level memory retention from both spiritual and potential corporeal origins

CAUSE OF DEATH (THEORETICAL ANALYSIS)

N/A: Boos are inherently spiritual; no corporeal death has been documented.

Hypothetical Origin:

Possible integration of Bowser’s soul into a Boo-form via a magical anomaly during the lava incident, creating a hybrid entity (“Dry Bowzer”) manifesting as King Boo.

Released from painting containment following Prof. E. Gadd’s experimental procedures in the mansion.

Result: Entity exhibits autonomous decision-making, tactical aggression, and pronounced malice toward living intruders.

PARANORMAL CHARACTERISTICS

Behavioral Pattern: Strategic, territorial, and manipulative. Commands subordinate Boos with telepathic influence. Exhibits selective aggression based on perceived threat or value of the target.

Manifestation Site: Mobile; most frequently observed in large-scale haunting events within mansion corridors, towers, and vaults.

Activity Cycle: Increased activity coincides with high-value intruder presence; active regardless of time of day.

Notable Abilities:

Command of Subordinate Boos: Telepathic control and coordination of multiple lesser spirits.

Invisibility and Intangibility: Can phase through walls, become fully invisible, or alter perceived size.

Poltergeist Manipulation: Can move objects, open doors, and trigger traps remotely.

Fear Induction: Emits a psychic aura that induces terror, hesitation, and disorientation in living intruders.

Teleportation: Instantaneous movement across large distances within the mansion.

PSYCHOLOGICAL PROFILE

King Boo exhibits characteristics of high-level intelligence, charisma, and cruelty. Motivated by vengeance and dominion, he is highly manipulative, exploiting fear and curiosity to achieve his objectives. Likely possesses residual emotional trauma from his hypothesized corporeal origin (Dry Bowzer).

Unlike typical Boos, he retains long-term memory and shows signs of personal vendetta and strategic foresight, suggesting a cognitive complexity rare among spectral entities.

CONTAINMENT PROCEDURES

King Boo remains uncontained following release from previous portrait experiments. Current containment strategies are under development, including:

Deployment of ghost traps calibrated for high-intelligence Boo-class entities.

Utilization of subordinate Boos to predict and restrict movement patterns.

Continuous monitoring via mansion-wide spectral sensors.

Engagement is limited to trained personnel with Poltergust-class containment devices.

Emergency Protocol:

In case of a large-scale intrusion or capture attempt, deploy mobile containment barriers and coordinate with subordinate entity neutralization. Direct engagement should be avoided unless high-level intervention teams are present.

NOTES FROM PROF. E. GADD

“King Boo isn’t just any ghost. He thinks, plans, and remembers. Whatever he is now—it’s not natural. I’ve never seen a Boo with such cunning or vendetta. Treat him like a general, not a poltergeist. And never, ever let him corner Mario.”
