Defeating the final boss in PATAPON 2 requires pure concentration and strategy. It seems awfully difficult with the first five tries and if you lack the ability to analyze this beast, it’s very hard to who. With the strategy and analyzation part, i’m going to help you with that.
I just finished the game today with so many trials and errors to memorize and fully understand the nature of that boss. Here’s what you need:
Equipment. You need a well optimised army of a hero in a Tatepon type, Toripons, Dekapons and Robopons. Equip a stew to boost up attacks.
Sequence. You begin with moving your army for about three forward marches and do the Pon Chaka (charge) and Pon Pon (attack) song simultaneously. Remember that it’s also only THREE forwards in case the boss moved away to the right and disappeared. If the beast moves away, charge up and attack him as he approaches you (always charge-attack, charge-attack) that’s one Pon Chaka song as the screen is on the beast. If the beast blows that sleep breath to you, do the Pon Chaka immediately because he’ll transform into that “grabber” form. You’ll be doing Chaka Pon twice to make them move back and if you’re doubting about the distance, do the Pon Pata (move away) after one Pon Chaka. If your hero gets grabbed, just quit and retry. But if you follow this tip well, you will not have to lose any of your troops.
IMPORTANT: make sure that ALL of your moves are done in PERFECT RHYTHM. That will enable your invincibility with your Tatepon hero. Errors and imperfection in pressing buttons will terminate your chances of winning this boss. And if you get your hero eaten up, you’re really dead.
Whatever happens, don’t give up. Just concentrate and perfectly do the keypressing. And follow my tips to avoid getting any of your allies taken by the “grabber”. You can defeat it without losing any patapon while maintaining an undamaged HP. Goodluck, gamers! May you reach Earthhend!
