Twilight Odin Twilight Odin is a boss in " Final Fantasy XIII - 2 " . He is the physical manifestation adopted by chaos , utilizing memories of the Eidolon Odin , and is fought by Serah and Noel in the Vile Peaks 10 AF and 200 AF after attacking a patrol ship full of Academy soldiers . After defeating Twilight Odin in the Vile Peaks 10 AF , the party receives the Twilight Fragment Alpha , and by defeating Twilight Odin in the Vile Peaks 200 AF , the party receives the Twilight Fragment Beta . " The malevolent Twilight Odin is the ' dark shadow ' that enveloped the Blitz Squadron in the Vile Peaks , 10 AF . " Datalog . " This entity exists outside time and can manifest in several eras at once . The source of its power , however , is but a single fragment , and the loss of this crystallized memory would weaken the shadowy being across every age . " " The creature known as ' Twilight Odin ' appears as a shadowy twin of the original Eidolon . In truth , it is a formless being of chaos that seeped into the mortal world from the Unseen Realm . This malignant force used a crystallized memory found in the Vile Peaks as a mold , and assumed the form of Odin . " " The memory belongs to a certain l ' Cie who saved Cocoon . It was in the Vile Peaks that she first faced and overcame the equine Eidolon warrior . " Battle . Twilight Odin heals its debuffs with Esuna . Constantly inflicting Wound damage will cause Twilight Odin to cast Thunder - elemental magic on itself , which both heals damage and restores Wound damage . If enough time passes Twilight Odin will use Zantetsuken to kill Noel and Serah ; should either of them survive , the Eidolon will use Zantetsuken again to ensure the battle ends . Strategy . Good paradigm s for this battle are : The player should start with an offensive paradigm , and get the chain gauge started , switch to Tri - disaster and stagger Twilight Odin . As soon as he is staggered , the party should switch to Bully and debuff him . Buffs on the party are not essential , although they may help . The party should switch back to Cerberus and land as many attacks as possible before the chain is reset . This should take Twilight Odin to half health , after which the procedure can be repeated . Facing Twilight Odin the second time , it is possible to debuff him from the start . It is best to start with Bully until Twilight Odin is fully debuffed . It isn ' t necessary to continuously reapply the buffs after Odin heals them . The party should switch to Tri - disaster and stagger him , switch to Cerberus and land attacks on Odin until the stagger ends or he dies . It is good to use a Feral Link ( if possible ) and full ATB moves just before the stagger gauge returns to normal . Paradigm Pack . Once Twilight Odin is defeated in the Vile Peaks 200 AF , he will join the player party as a Commando . His development is slow at first , but his stats ( particularly his HP ) rapidly accelerate during the last stage of development . He is expensive to develop , requiring 269 monster materials in total to reach level 99 . Once he reaches his maximum level , Twilight Odin is one of the most powerful monsters . A disadvantage is that he has slow animation speeds , especially when casting magic ; he also requires decently wounded enemies to deal a good amount of damage , due to his Bloodthirsty auto - ability . Twilight Odin ' s Blitz attack does good area - of - effect damage , so it is best to use him in a - W formation paradigm . His Feral Link is good for recruiting monster crystals as his Zantetsuken Feral Link gets close to 999 % synchronization when performed perfectly . Twilight Odin is a one - of - a - kind monster . If the player releases him or infuses him into another monster , the player will be unable to obtain another Twilight Odin unless they have downloaded Snow ' s DLC episode , in which a Level 99 Valfodr has Twilight Odin as a rare drop . Other appearances . " Final Fantasy Trading Card Game " . Twilight Odin appears in the " Trading Card Game " on a single card . His card is part of the " Thunder " set .
