Undine

Undine (ウンディーネ) is the Summon Spirit of Water, also representing one of the four cardinal elements of the Tales games. Undine has appeared in several games of the series as characters and cameos, and she may be able to be summoned through the Undine arte. Undine is opposed by Volt, the Summon Spirit of Lightning. In Tales of Rebirth, Undine is replaced by Shaorune, the Sacred Beast of Water. In Tales of Graces she is replaced by the spirit Syan Deem.

Appearances
Undine is the Summon Spirit of Water. As the series progresses, her appears leans more toward the merperson; her original Phantasia appearance is that of a sword-wielding sprite.

Tales of Phantasia
Undine appears as a tall woman wearing blue flaps and cloth over her body with a sword. Found in the Limestone Cave, she is one of the first four Spirits that the party must face before they can meet Maxwell, the Lord of the Four Elements. She initially fights the party because they woke her up, though after defeat she assents to making a pact. It is through her power that the party is able to reach the sunken city of Thor. Undine requires the Aquamarine Ring to forge a pact, granting Klarth F. Lester with the power to summon her in battle with the Undine arte.

When fought, Undine primarily acts as a caster. She brings into battle with her various monsters and proceeds to cast various water-element spells, such as Ice Needles, Ice Wall, and Ice Tornado. She can also strike enemies with her sword and send a cutting wave from her blade across the screen.

Tales of Destiny
Undine can be summoned through the consumable item "Wendiene" (a clear mistranscription of Undine's own name, as it bears the same katakana in the Japanese version), which is described as an ancient weapon capable of calling forth the water spirit.

Tales of Eternia
Undine represents one of the Greater Craymels and one of the Primary Craymels of Inferia. The Water Craymel governs the use of all water element spells. Undine makes her home in Undine Stream. With her steely personality, she is the first Greater Craymel encountered and tests their will. It is her power which lets the party survive the intense heat of Efreet Gorge, and when Efreet refuses to help, she forces him inside the Craymel Cage. Undine can be summoned through the Undine arte.

In battle, Undine fights using her trident. Her main attacks are her Spear of Baptism (洗礼の矛槍), which sends a stream of water across the screen if unblocked, and Subterranean Divide (峻別の伏流), in which she sends out a small-range projectile. She can also cast Spread.

Tales of Destiny 2
Undine is a cameo appearance in the Hi Ougi Aqua Rimms (アクアリムス).

Tales of Symphonia
Undine, the Maiden of the Mist, appears in an amphibian-like form, with completely blue skin and "clothes" that seem fused to her skin and is one of the Sylvaranti Summon Spirits. Residing on a small island known as "Thoda" famous for its geyser, she is the Summon Spirit of Water. She is able to be summoned through the Summon: Water (降霊召符・水) arte, which will display Undine's name after the arte's name.

Undine's main method of fighting is casting Spread. She will also strike with her sword if possible, and she can cast Aqua Edge without a casting time.

Tales of the Abyss
Undine is mentioned in one of the texts of the library in Daath, with her name used to represent the fourth day of the week, Undineday, and the third and tenth months, Undine Decan and Undine Redecan respectively. The spear "Undine" names her as the aggregate sentience of the Fourth Fonon, the Fonon of Water.

Tales of Vesperia
The Entelexeia Belius is inadvertantly turned into a spirit while Rita Mordio attempts to control Estelle's powers using her apatheia. The spirit has control of all waters, and asks Estelle to name her. Estelle promptly names the new spirit Undine, meaning the Ruler of the Waters. Much like Belius, Undine has much support for the humans and, when the four Spirits converse, speaks the most for them.

In the PS3 port, Undine appears during Estelle's mystic arte Ultimate Elements, where, after Sylph performs her cyclone, she unleashes a tidal wave which drowns her foes.

Tales of Phantasia: Narikiri Dungeon
Undine is the Spirit of Water and one of the twelve Spirits which must be fought during the Ordeal of Spirits. She is found on the final level of the Cave of Water in AC. 4203 and is the boss of that dungeon. Upon defeat, she teaches Mel and Dio the heart of water: presence of mind (へいじょうしん).

Tales of the World: Summoner's Lineage
Fulein K. Lester can summon Undine as a unit.

Tales of Symphonia: Dawn of the New World
Undine appears in a hot springs scene, where Sheena Fujibayashi summons her to send water at Lloyd Irving and Emil Castagnier, after they were tricked by Zelos Wilder. Based on the location of the other Centurions' cores, it can inferred that, had Aqua, the Centurion of Water, not already been awake, her core would have been found at Undine's home at the Thoda Geyser. In reference to her position as the Summon Spirit of Water, her name is attached to monster grimoires which teach water elemental artes: Undine's Whisper, which teaches First Aid, Undine's Affection, which teaches Heal, Undine's Charity, which teaches Recover, and Undine's Tears, which teaches Splash.
