need help on final boss!!!!!!!!!!!!!

Well, you need to wear power rush, at least twoof the poer up and defense up badges, feeling fine, mega rush, any health badges you have. On the first form use spring jumps, the next, use like a reg. Jump or some thing like that. On the last form, use spring jumps and supernovas. Memorize her attacks and when to block!!!!!!

Do you mean Shadow Queen? Or do you mean Bonetail in Pit of 100 Trials? I have a feeling you mean Shadow Queen. Ok, make sure you have some healing items (Good ones, too, like Jelly Ultras (Ultra Shroom + Jelly Jar(I don't know what it is called))!). Try your best to appeal as much as possible WHILE attacking. That way, you get a ton of SP. You can use Power Lift, to raise your power, and Supernova, for big hits! That is a good combination. Don't forget to use FP for moves involving badges! Try to have good dodging, too. Good dodging can get you pretty far. As for partners, use the most powerful of them (I don't have an actual opinion on the most powerful though.). It would also help to have a Charge badge and/or Charge P Badge. You and/or your partner could supercharge any attacks to make them super powerful! This helped me a lot in the last battle. I hope this helps!

Do what I did and max out your HP,FP and BP. I had beaten her on my first try.

Listen, Just equip charge badge, power up, and power bounce and use your partners as shields, keep charging up, then just before you attack, use the power lift special move (I don't think doing it twice changes anything really, it just resets it) And then power bounce. Keep doing it and get the action commands right and you'll easily win. In fact, I won in one shot like this with bonetail...

All or nothing badge helps too if you're REALLY good at action commands like I am.
