It seems the fated time is here at last. We, the three Mage-Sisters, will bring this battle to its end... ONCE AND FOR ALL!
~ Zan Partizanne before the Three Mage-Sisters fight the heroes together.
The Three Mage-Sisters, also known as the Jambastion Mages, are a team of three Mages led by Zan Partizanne who are members of the Jambastion Cult and followers of Hyness. They are the secondary antagonists turned playable characters (as of the Wave 3 update) in the game Kirby Star Allies and the main antagonists of the sub-game, Heroes in Another Dimension.
Prior to the start of Star Allies, the Mage-Sisters were normal girls who were on the brink of death due to an elemental hazard: Francisca was caught in a blizzard, Flamberge was trapped in a fire, and Zan Partizanne was struck by lightning. Hyness came to their rescue and granted them elemental powers of ice, fire, and electricity, respectively. In gratitude for their rescue, the three became Hyness' followers.
Kirby Star Allies
After Kirby defeated Meta Knight, the Jambastion Mages landed their Jambastation on Planet Popstar. Kirby went to fight them, defeating Francisca first, followed by Flamberge, and finally Zan Partizanne. After her defeat, Zan uses her powers to destroy the Jambastation to take Kirby down with it, but he and his allies manage to escape.
Kirby later encounters Francisca and Flamberge again on different planets and discovers they are gathering Jamba Hearts for a nefarious purpose. After defeating them, Kirby follows them to their base where he finds their master, Lord Hyness, conducting a mysterious ceremony. As he approaches the dark officiant, Zan Partizanne appears and blocks his way before engaging him in a fight.
After being defeated, Zan begs Hyness for his help, only for Hyness to cast her out of the way and fight Kirby himself. After being defeated once, Hyness summons the three mage generals to him and hypnotizes them before draining most of their life force to revitalize his own. Hyness then engages Kirby again, using the Jambastion mages' bodies as weapons and shields against Kirby.
Defeated again, Hyness turns his attention back to the ritual and discovers the Jamba Hearts are not enough to finish it. He then chooses to sacrifice himself and the three Jambastion mages to complete the ceremony and summon Void Termina.
After being sucked inside Void Termina, Kirby finds the Jambastion mages, along with Hyness, trapped inside it. He releases the core, ejecting everyone, including the Jambastion mages, out of Void Termina.
Heroes in Another Dimension
Following Void Termina's defeat, the Jambastion mages and Hyness survived and found their way into Another Dimension, in search for another vessel to summon Void Termina again. After Corrupt Hyness is defeated, Zan Partizanne comes to his aid. Blaming Kirby as the one who brought the Void to corrupt Hyness, she rallies Francisca and Flamberge to avenge their master and destroy Kirby. Despite their power, Kirby and allies are able to best the Mage-Sisters and defeat them.
If Kirby had collected at least one-hundred of the one-hundred and twenty heart pieces in the four Dimension levels, he can create a giant Friend Heart to cleanse the three sisters of the Void, returning them to their senses. They instead use their powers to rid the Void and bring peace to Another Dimension. They create a large warp star for Kirby and friends to ride back to their home dimension and wave goodbye before comforting Hyness when he wakes up. After this, the Mage-Sisters become a singular Dream Friend.
Super Kirby Clash

All three also appear as individual stickers that can be bought from Magolor's Shoppe for thirty Gem Apples each.

Kirby Star Allies - New Final Bosses & Secret Ending (Solo Kirby)
The relationship between the mages is never stated in-game, although Hyness' pause descriptions refer to them as "sisters", though this could mean that they are members of a sisterhood rather than biologically related, as in the original Japanese description they are referred to as nuns.
Kirby Star Allies is the first Kirby game where religious themes (being Christian, due to the Mages' theme/battle music "Prayer Song to God) aren't censored in the US/PAL release. This has likely to do with cultural and societal changes in the West.
If the Mage-Sisters are purified, they will appear in the audience during the credits of "Heroes in Another Dimension".
Soul Melter EX reveals reveals part of their backstory; the reason why the Mage-Sisters are so loyal to Hyness despite him abusing them is because he once saved them from certain death, giving them magic abilities and a new purpose in life.
Fuse Man from Mega Man 11: Gears of Fate moves around his room in a similar manner to how Zan Partizanne typically moves.
After obtaining the true ending of "Heroes in Another Dimension", there is a random chance that the Mage-Sisters replace the Waddle Doo, Waddle Dee, and Burning Leo in the game's Sound Test.
