Proto Ultima
“Along with the Ultima Warrior, Proto Ultima is one of several prototypes created by the Allagans in their long journey towards the completion of the Ultima Weapon. One of the most distinct differences between this model and the final is that at this point in their research, the Allagan scientists still had not discovered a means to protect a pilot from succumbing to the will of any primal absorbed by the machine, thus forcing them to employ a less-reliable artificial intelligence unit.
