Braska ' s Final Aeon ( Final Fantasy X ) Braska ' s Final Aeon is the last boss of " Final Fantasy X " the player can lose against under normal conditions . Although Yu Yevon is fought afterwards as the final boss , it ' s impossible to die in that battle short of self - incapacitation , making the battle against Braska ' s Final Aeon the last challenge in the storyline , and is often considered as the " true " final boss . Battle . The player starts the battle with Tidus , Yuna and Auron . Braska ' s Final Aeon is fought in two stages . Upon taking enough damage , it will draw out a gigantic sword and gain a new ultimate attack . Braska ' s Final Aeon is flanked by two Yu Pagoda s that remove statuses and use Power Wave to heal Braska ' s Final Aeon for 1 , 500 each time and increase his Overdrive gauge . The Pagodas each have 5 , 000 HP and can be killed , but will return a few rounds later with increased health equal to the amount of excess damage by their finishing blow ; for example , if they start off with 5 , 000 HP and are dealt two attacks worth 2 , 700 and 2 , 600 respectively , they will revive with 5 , 300 HP . Braska ' s Final Aeon has an Overdrive gauge that fills as he gives and receives damage , and when he is healed by the Pagodas . Tidus can reset the gauge by talking with a Trigger Command , but this can only be done twice and should be reserved for the battle ' s second half . Jecht Beam can cause petrification , and his standard attack can shatter a petrified character . The Triumphant Grasp Overdrive will cause heavy damage ; during the first form it also inflicts the Zombie status . When faced with an aeon , Braska ' s Final Aeon will use Jecht Bomber as an alternate Overdrive , which can do up to 4 , 000 HP damage . He has a skill that can cause Sleep , Poison , Darkness , and Silence simultaneously . In his second form , Braska ' s Final Aeon will draw a mighty sword from his chest , and spikes that resemble wings emerge from his back . He will hit all party members at once , delay their turn slightly , and do more damage than before . Though not directly named , his sword swipe is called Blade Blitz in the game ' s data files . When Braska ' s Final Aeon ' s HP falls below half , his Overdrive will change to Ultimate Jecht Shot , which can hit all characters for around 5 , 000 damage . Against aeons , he continues using Jecht Bomber as an Overdrive . Braska ' s Final Aeon is vulnerable to several status ailments , most notably Zombie . Strategy . With Celestial Weapon s and the Break Damage Limit ability players who decide to do those sidequest s before entering the final stages will find the battle easy . To protect against petrification , the player can equip Stoneproof armor . It is best to kill the Pagodas off at the same time , as the remaining Pagoda will spam Curse and other nasty spells . Since the Pagodas initially take their turns right after one another , it may be effective to cast Slow on one of the Pagodas separating their turns and minimizing the effectiveness of their Power Wave . Jecht Bomber can be reduced to a quarter of the normal damage by using the aeons ' Shield and further by using Cheer . When Braska ' s Final Aeon enters the second battle phase and starts charging for Ultimate Jecht Shot , Tidus should use his Talk command . Keeping the party members ' HP up is vital . Buffs such as Protect , Haste and Regen are useful , and if Yuna has learned Auto - Life , it will also help . Using Stamina Tonics to double the party ' s max HP is good , especially when coupled with Break HP Limit . Doublecasting Flare and Ultima and using plenty of Overdrives will prove effective . Possibly the easiest strategy is as follows : Yuna should have finished her Sphere Grid path and started on a new path by this time . If she is taken down Tidus ' s or Auron ' s path , she can quickly develop her strength attribute , which magnifies her aeons ' strength . If Yuna has Anima available it can potentially destroy the Final Aeon ' s second form in just two hits , by inflicting up to 99 , 999 damage per hit . Even without Anima , Bahamut ' s Overdrive , along with a couple of regular attacks , should dispatch of this boss , provided Yuna ' s strength attribute is at least 28 . Shiva ' s Overdrive is also potent , with damage figures around 40 , 000 not being unusual for an average - stat player ( providing the player has upgraded Lulu ' s Onion Knight with the Venus Crest first ) . Though it may take a few tries , the player can Poison the boss , and Auron ' s " Break " skills can take effect as well . Braska ' s Final Aeon is not immune to Zombie , so if the player uses Zombie Attack the Yu Pagodas will damage it rather than heal it , although the Yu Pagodas will also remove these status ailments on their turn . An easy way to deal a lot of damage fast is to get Rikku to mix two Wings to Discovery to make Trio of 9999 , which makes every attack do 9 , 999 damage . With this Tidus ' s Slice & Dice should deal ~ 50 , 000 damage , and Wakka ' s Attack Reels can take out a whopping 119 , 988 HP . Rikku herself can use a Gem , which will do another ~ 50 , 000 damage . For those who wish not to use gamebreaking methods , a common approach is to Doublecast Flare or Ultima with a high Magic character who does not have Break Damage Limit to keep the Yu Pagodas dead by consistently hitting them for exactly 9999 , while minimizing the hazard presented by Braska ' s Final Aeon himself through use of Power Break and Protect , and perhaps Cheer . With maxed stats and use of the Celestial Weapons , the battle can be won in three hits ( one - hit kill for the first half and two for the second ) . If this method is taken , the Yu Pagodas can be ignored , as they will never get a turn . Other appearances . " Dissidia Final Fantasy " . Braska ' s Final Aeon appears as Jecht ' s EX Mode .
