#Media Origin (Alteration Needed)

CategoryAlteration Principle
D&D general (goblin·orc·troll)generalized·close to public domain — original name or altered (e.g., Goburin)
D&D proprietary (Mind Flayer·Beholder)alteration mandatory (Brain-Eater·Many-Eyes)
Tolkien proprietary (Hobbit·Ent)alteration mandatory or avoid use
comic·novel media (specific characters)alter + borrow only the motif
film·game (specific weapons)alter + only the motif

#Alteration Principle

  1. Name: alter in Chinese characters or Korean.
  2. Appearance: borrow only the motif. Change the exact appearance description.
  3. Ability: reinterpret in core-rule format. Not the original ability as is.
  4. Source notation: an academic-citation format such as "orig: D&D Mind Flayer" (where possible).

#§ 1.5. Integration Handling of Core Same-Name Yoma

When a name overlaps with a yoma that already exists in the core 08-02 Yoma Bestiary, the principle is integration into the core and deletion (a matter of internal consistency, not an IP issue).

Old LocationNameCore EntryHandling
55-08-01Nine-Tailed FoxLord-grade (Tamamo-no-Mae)delete — core integration
55-08-03NueElite-gradedelete — core integration
55-09-01GakiMinion-gradedelete — core integration

A separate naming alternative ("Chinese Nine-Tailed Fox," etc.) is also possible, but for the 4, integration is recommended.
