No, Guardianship/Z-Tokens are non-transferrable. Guardianship/Z-tokens cannot be transferred from one character to another, or from one account to another. Guardianship/Z-Tokens cannot be transferred from AdventureQuest to any other Artix Entertainment LLC game.

Since a Guardianship upgrade or a Z-Tokens purchase is a one-time payment, not a monthly fee, it simply is not appropriate to be able to transfer Guardianship/Z-Tokens.
