Johan Cydr
Type	Human
Role	Neutral
Home World	Unknown, first appeared in Hollow Bastion.

Dr. Cydr is a renowned mathematician and was commissioned by the The League of Abstraction to describe the patterns of heartless and Nobodyies mathematically, he is one of the leading scientists in the department of Abstract anatomy and ecology.

The Heartless Respawn Equation

$T=M(-D/L)$

where T= the time in days taken between the heartless "death" and "reformation" M= the Heartless's mass and -D/L is equal to the Ratio of Darkness and light in the subjects heart measured in Globs

A glob is a unit used to measure Darkness and light, it is equal to the minimum amount of darkness necessary to form a glob of pure darkness, hence the name, this is defined as the weight of the smallest ever created glob which is kept inside of a vault in his laboratory and weighs approximately 2.675 Kg. and since light is the opposite of Darkness than a negative glob can be used to measure the amount of light.

Nobody Type formula

Failed to parse (syntax error): {\displaystyle B₁−B₂=R(m/B₂)}

where B= body R= the globular ratio and m is a variable that represents the amount of memories that have been divided into B₂

this can be used to determine the amount of physical change that occurs to the body when it becomes a Nobody.

this formula is used extensively in the Heart regrowth hypothesis, which states that if a Nobody who's core memories were copied onto the body than if given the right conditions those memories would form into a new heart.

The formula is also used to determine the "Realism factor" of remembered emotions.

Summoning Ansem

using this equation they were able to make a rough estimate of when Ansem would reappear, and they need to capture Castle Oblivion, the location of his recreation before that time.
