King

Caldia's Orb is an orb formed in Caldia, the island of magic users, to contain the most evil of evils, and thus was locked away in Caldia's floating palace. After influencing both Phantom and Diana with its thoughts, Caldia's Orb was freed by the two, and the three together formed the Chess Pieces with the Orb as King. The Orb entered Babbo for Phantom to use as a weapon, and after Phantom's death possessed Danna's body as a new host with which to control the Chess Pieces. While awaiting Phantom's revival, the Orb concocted a plan to conquer both MÄR-Heaven and Earth alongside his Queen.

Caldia's Orb's only thoughts are those of pure malevolence, though, ironically, hates the human race for such sins as well. The true form of the evil that is the Orb is an eyeless corpse wielding a scythe, a perfect form for something of such impurity. The anime shows the Orb having other abilities, such as strangling enemies without touching them in a manner similar to The Force from Star Wars, and immediately killing those who touch its deadly aura. The Orb, following the defeat of Phantom, decided that all of the Chess Piece soldiers, outside of itself and Diana, were useless pawns and massacred all of them, the only survivors being those who already abandoned the Chess.

The next step to total victory the Orb devised was the annihilation of Team MÄR, killing all of its members outside Ginta and Jack. Following Diana's defeat, the Orb challenged Ginta and revealed its form of Danna. Though at first discouraged to fight his father's body, Ginta eventually managed to use Babbo to draw the Orb out of his father and put Danna's soul back in its rightful place. In the manga, the Orb then entered Babbo and battled Ginta, who entered Babbo as well, and was defeated right there, its remains a magic stone for Babbo. In the anime, the Orb escapes to Earth and begins wreaking havoc.
