Proto - behemoth ( Final Fantasy XIII - 2 ) Proto - behemoth is an enemy in " Final Fantasy XIII - 2 " . It is the final behemoth to be encountered in the course of the storyline and the strongest one , as well as the only one to count as a Militarized Unit ( the others are Feral Creature s ) . Proto - behemoth is also one of the three creatures that can be summoned by a Mimi . The Mimi is accompanied by between three and five Bamapama s ; a Xolotl is always summoned when there are two or three Bamapamas remaining on the field ; if four or five remains , the Mimi summons a Proto - behemoth ; if one or none are alive , a Managarmr is summoned instead . The Mimi itself is invincible while summoning . The chances of taming a Proto - behemoth summoned by a Mimi are so low that it can be considered almost impossible to recruit one . In random encounters , one can only find this enemy at the end of the labyrinth . When faced as a random encounter it is always accompanied by two Schrodingers . If it is defeated , it ' ll never reappear unless the player closes the Academia 500 AF Time Gate and travels all the way to the final platform again . Battle . Like its counterparts , Proto - behemoth begins quadrupedal and can transform , standing upright bipedal , healing completely and pulling a saw - blade melee weapon out of its back . In this state it uses elemental magic and powerful moves like Sunder . Strategy . It should be taken out first because if it transforms it can turn the battle to its favor , as its attacks when standing on two legs are extremely powerful , and combined with the Schrodinger ' s Deprotega spell they can deal up to 4 , 500 - 5 , 000 HP damage to the entire party . It is good to start the battle with a preemptive strike to get Haste , switch to Tri - disaster ( RAV / RAV / RAV ) to build its chain gauge high enough , then switch to Cerberus ( COM / COM / COM ) and attack until it falls . The party should also use Diversity ( COM / RAV / MED ) occasionally to heal . This is also the best strategy for attempting to acquire its crystal . Paradigm Pack . Proto - behemoth is tricky to acquire due to them only appearing once naturally at the end of the floating maze in Academia 500 AF with two Schrodingers , requiring the player to target the Proto - behemoth first and retry the fight if they do not receive its crystal , or saving and reloading , or closing the gate . Proto - behemoth is a Commando . It is easy to max out by the time they can be recruited , only requiring Essence grade materials to complete growth at highest level s ( can be bought from Chocolina ) , and a level cap of 40 instead of the usual Behemoth species ' s level cap of 70 . However , due to this , it has less potential for growth and with three red - locked abilities it loses out in the long run to a maxed Narasimha ' s stats and with its 4 ATB bars available if only Commando role bonuses are chosen during growth for both , Proto - behemoth having only 3 ATB in this circumstance . Only one Commando bonus boost is available in contrast to other higher level Commandos with a level cap of 70 or more . Its Feral Link , Sunder , hits its target plus any targets in its way . It has a maximum synchronization rate of 300 % . Its sword lets it hit opponents without the need to get close , and it can attack launched opponents without magic . After Chichu , it is the second best Armor Breaker user outside of DLC content , since other Commandos with it forgo Armor Breaker in favor of Stagger : Wound or Stagger : Drain once an opponent has been stagger ed . It also learns Bravery Feeder . Due to its three red - locked passive abilities , Proto - behemoth functions in Synergist - like fashion in critical condition . Proto - behemoth is a very powerful Commando especially for one who doesn ' t care for hours of farming Power Crystals to power up Twilight Odin , Narasimha , or Chichu .
