Dreamy Mario
Dreamy Mario (Called D Mario in PAL versions) is a clone of Mario who is a boss in Mario & Luigi: Dream Team. He is identical in appearance to Mario but has a purple colour and is stronger.
Battle
When fought in Dream World, Dreamy Mario uses several attacks such as running into Mario, copying Mario's attacks (inclusive using items), making clones of himself and making his damaged clones charge at Mario.
Clones attack the same as Dreamy Mario, but when they are attacked, they will charge in Mario at high speed, and as it must be countered with the hammer and they come immediately after each other, it's almost impossible to avoid this attack.
Dreamy Mario can only be damaged using perfect attacks, and he can heal himself with 18200 HP (all his HP) whenever he wants. Also, using unperfect attacks or Dreamy Mario's attacks can instantly kill Mario and since you can't use easy mode, this battle is harder than ever.
