Numbering in Z/X

In Z/X -Zillions of enemy X- TCG, several Z/X shared the same title with numeral in their names. These titles were collectively referred to as "numbering name" (ナンバリング名) in official sources and often held a significant importance in the story. Most of the holder of these titles already possessed it since their introduction in story. But some of them also gain it later through the course of the story, especially for newly introduced titles.

In the card game, these titles were mostly one-off occurrence per characters (e.g. only one card with the title for a given character) although the holder may also retain the title on several cards in rare case. Cards with the titles often benefit from support given by other cards that specifically refer to the titles in its ability.
