Dreamy Mario

Dreamy Mario is a clone of Mario that appears in Mario & Luigi: Dream Team. He was created by Antasma to defeat Mario and Luigi while he watches over him doing so with Princess Peach in his grip. He serves as the first boss fought in the Dream World, and is identical in appearance to Mario if the purple cloud that surrounds him is not counted. As he is created at the start of the battle and destroyed at the end, he has no overworld sprites.

Battle
In battle, Dreamy Mario will primarily attack with a herd of weak clones by having them charge at Mario, who can dodge them by jumping or stepping out of the way. If the main clone is stomped during this attack, the attack will instantly stop. Any clone Mario ends up stomping, either by counter-attacking or directly attacking will fly back at Mario from the top right corner of the screen after the turn, at which point they must be dodged again through jumping. Like Beta Kretin from Mario and Luigi: Bowser's Inside Story, whenever all the clones are defeated, Dreamy Mario will spawn a complete new set of clones and try to shuffle itself amongst them to avoid direct attacks from the real Mario; if Dreamy Mario is directly attacked by Mario, all the clones vanish, but Dreamy Mario will immediately recreate the clones and reshuffle itself in the mass. Occasionally, Antasma will directly attack by laying out a stream of coins interspersed with fireballs and the occasional Mushroom, which Mario can use to heal himself. Antasma can also attack by having Mario chase after him while he sends out waves of invincible Mario clones running towards the player; as the attack goes on, Antasma will begin to create streams of purple gas to obscure a vertical line of Mario's view and hence make it more difficult to spot (and jump over or avoid) approaching clones.

Mario eventually manages to destroy his 'dreamy' counterpart, but ultimately the battle does not accomplish its intended purpose of retrieving Peach: Antasma uses his sonar beams to blow a hole in the floor all the way to Dream's Deep and flees down said hole with Peach, closing it soon after. The hole's closure would mark the last time the bros. would see Peach until they arrived at Dream's Deep.
