In the Yu-Gi-Oh! manga, their stats were multiples of 100. The night terrain concealed PaniK's monsters, but did not affect their ATK or DEF.
In the video game Yu-Gi-Oh! Duel Monsters, the Field Spell Card "Yami" boosts their ATK and DEF by 30%. To preserve the stats they had in the manga, the original ATK and DEF of these monsters (except "Reaper of the Cards") were modified so that after the boost by "Yami", their ATK and DEF would approximate the values they had in the manga; then, unlike other monsters in the game, the stats of these monsters were rounded to the nearest 100 after receiving the boost from "Yami".
In the anime, the night terrain boosts the ATK and DEF of these monsters by 30%. The same values as the video game Yu-Gi-Oh! Duel Monsters were used, but unlike that game, their ATK and DEF were not rounded off.
|Card||Base||Base + 30%||Manga|
|Castle of Dark Illusions||ATK||920||1196||1200|
|Reaper of the Cards||ATK||1380||1794||1800|
|King of Yamimakai||ATK||2000||2600||2600|
- Manga "Barox" was shown to have 2000 DEF in some scenes, but 2200 in others; later printings changed to always be 2200. The non-manga DEF is based on the 2000. In Yu-Gi-Oh! Dark Duel Stories and Yu-Gi-Oh! Duel Monsters 4: Battle of Great Duelist (which both use the manga stats for these monsters), this monster has 2000 DEF.
- The boosted DEF does not match the manga. 1930 may have instead been chosen to contain a reference to gods of death.
- Manga "King of Yamimakai" was shown to have 2000 DEF in some scenes, but 2300 in others; later printings changed to always be 2300. The non-manga DEF is based on it having 2000 DEF. In Yu-Gi-Oh! Dark Duel Stories and Yu-Gi-Oh! Duel Monsters 4: Battle of Great Duelist (which both use the manga stats for these monsters), this monster has 2300 DEF.
Reaper of the Cards
The stats of "Reaper of the Cards" may have been chosen so that the digits in the ATK and DEF become 1-3-8-0-1-9-3-0, which, when read variably according to goroawase pronunciations, can be interpreted as himitsu yama, ikusare (秘密山、行くされ), similar to "go to the secret mountain", a possible reference to gods of death in Japanese folklore.
