70 hp (max hp 150)
This dark version of Peach isn't too bad... yet. She'll get much stronger in a
different form; this will just be a warm-up. Although she has 150 HP, give her
about 70 damage and this part of the battle will end. So... my recommended
party is Mario and Yoshi. She'll be doing some pretty strong attacks (about 8
damage or so) but still not that much of a concern. My first attack during this
fight was Supernova, which did 15-16 damage. What I did after that was use
Power Bounce and Stampede, until I got 4 SP.
Art Attack works REALLY well here, believe me. Since Peach's body isn't really that big (taller than Mario though =P) you can circle around her several times and do 15-18 damage even more than Supernova. Eventually she'll switch to her true form. UGLY but that's not the problem. You can't harm her now; focus on trying to defend yourself although don't waste your Ultra Shrooms trust me. Just continue as you are and keep yourself alive. She'll drain your HP and the audience while you can't hit her that's not nice.
SHADOW QUEEN II hp 150
Art Attack doesn't work as well as it did the previous time, because there are three enemies and she's MUCH bigger this time. So start off by using Supernova with 16 damage to her and her stupid hands. Yeah, they'll try and suck you and your partner's HP while she restores it and uses even stronger attacks. The hands shouldn't be that much of a priority though. Anyway once you have the hands out of the way attack the Shadow Queen with every inch of power, since she has the second most HP of any enemy in the game. She WILL bring those damn hands back, but they're not really too annoying. For the partner for this battle, anyway my recommendation is Koops for the first half Vivian for the second half. Koops's fourth skill is just plain invaluable while Vivian's Fiery Jinx and Veil abilities will help in the second half of the fight. While you mow through the hands try and protect yourself while putting on Power Bounce almost every turn. Eventually the Shadow Queen will replace the normal Hands with Dead Hands. Don't even look at these although it's good if you use Koops/Vivian and use your strongest attacks to take them out with the Shadow Queen. By now, she'll be weakening anyway. At that point use every single thing you have left all your Ultra Shrooms and everything (my Mario had 55 HP at this fight, by the
way). Use Veil when the Shadow Queen charges herself up, and you shouldn't have many troubles.
shadow queen 3 you can go for it good luck
