405.2.

Some objects have intrinsic static abilities that define the object's colors, subtypes, power, or toughness. These abilities are characteristic-defining abilities, and they function in all zones. Abilities of an object that affect the characteristics of another object are not characteristic-defining abilities. Neither are abilities that an object grants to itself, or abilities that set the values of such characteristics only if certain conditions are met. See rule 201, "Characteristics," and rule 418.5a.

405.2.

A characteristic-defining ability is a kind of static ability. It conveys information about an object's characteristics that would normally be found elsewhere on that object (such as in its mana cost, type line, or power/toughness box). Characteristic-defining abilities function in all zones.
