dang nice, looks like an early final fantasy boss

He is a transformation of the player character Vincent.
It looks like behemoth, but it is not actually behemoth.
The name of this beast figure is Galian Beast.

After transforming, he fights as an instinct as a Berserker.
The transformation cannot be solved until the battle is over.
(Even if it is petrified, it becomes a stone statue as it is.)

OH GOD THAT'S RIGHT i totally forgot about that! I haven't played that game in so long.

could one choose to make the transformation perminet because this is something i would refuse to change out of

It's Vincent's Galian Beast! Amazing work!
