110.5b

The spell or ability that creates a token may define the values of any number of characteristics for the token. This becomes the token's "text."

Voice of Resurgence.  A token created by Voice of Resurgence has a text; "This creature's power and toughness are each equal to the number of creatures you control."

The characteristic values defined this way are functionally equivalent to the characteristic values that are printed on a card; for example, they define the token's copiable values.

The Scarab God. If Clone copies a token created by The scarab God's activated ability, it's 4/4 regardless what the token is.

A token doesn't have any characteristics not defined by the spell or ability that created it.
Example: Jade Mage has the ability "{2}{G}: Create a 1/1 green Saproling creature token." The resulting token has no mana cost, supertypes, rules text, or abilities.
