As an Alternste Form, you are accepting that you may be needed in any chapter that the normal form of your character is in. You essentially act as a secondary character, as you may be needed randomly for any lines. This role is treated with similar importance to the normal version of the role, so please consider this an extention of that role.

Whenever he transforms into his "true form", his pride and ego further increases, as he makes his personality reflect his mighty appearance. He can also act more mature and serious in this form, and present a more aggressive and threatening side of himself. Despite that, he's still the same Pixiu as usual, and can still act childish and shameless while in this form.

As the larger version of Tianlu, one main factor for casting will be how closely this voice can gel with whoever we end up casting as Tianlu. This means that Auditions here will be impacted by the casting of that role.
