Invasion to Earth
It is unknown how he joined Queen Mirage. He is presented when she begins her invasion along with the other generals, but he did not appear until episode 13.
Confronting Megumi and Blue
He shows that he holds a grudge against Blue for their loyalty towards Queen Mirage so he despises Blue. Lovely fought him but he evade it. Just as he almost finished her, Fortune arrived in rage and sought revenge on him for defeating Cure Tender. His power is too strong enough for her. Lovely and Fortune work together and fight him. Their attacks force him to bring his sword but was intervened by Blue, saying that killing them won't be Mirage's wish. Phantom then took his leave and said that he will spread misfortune to the world for Mirage.
Fighting Cure Fortune
He creates several Saiarks to lure the Cures, when Fortune saw him, she followed him. Fortune fought him in rage until he brings her to his lair and they are about to duel. He easily overpowered her, de-transformed her and took her PreChanMirror, learning that Cure Tender was her sister and that she sacrificed herself to protect Iona. He then burns her PreCards and said she would never transform again or save her sister, plunging her into despair. Before he could imprison her, the other Cures arrived and Hime gave her all of their PreCards, completing her file and restoring her powers. With those new powers, she turned the tables and severely injured him with her Starlight Ascension attack. As he is about to attack again, Queen Mirage appears and interrupts the battle. He is brought back to the Phantom Empire soon after and she scolds him for attacking Pikarigaoka and the Happiness Charge Pretty Cures without her knowing, but she ultimately spares him his life.
Plotting Against Blue and Cure Lovely
After the three generals fail, Mirage calls upon him and tells him to kill Blue along with Cure Lovely, which he delightly accepts. In episode 30, he confronts Megumi and Blue. After Megumi transformed into Cure Lovely, they fought for a while before Phantom extracted Lovely's shadow and merges with it to become Cure Unlovely. In this form, he is way more powerful, even to the point of breaking Lovely's spirit and cause her to fall into despair. After her friends encouraged her to continue, she fought Unlovely once again, undoing Phantom's transformation. The resulting strong bond in friendship allowed the Cures to use the Shining Make Dresser to perform Happiness Big Bang and defeat Phantom.
