Undine

Undine, the Maiden of the Mist (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 through spell summons and cameo appearances. Undine is opposed by Volt, the Summon Spirit of Lightning.

As a summon
Undine first appeared in Tales of Phantasia, as one of the first four Summon Spirits that the party must face before they can meet Maxwell, the Summon Spirit of Matter. Undine requires the Aquamarine Ring to forge a pact, granting Klarth F. Lester with the power to summon her in battle. When summoned, Undine appears at the left side of the screen, and she races across the visible battle field with her sword, dealing water element damage to all enemies who are hit by her.

In Tales of Eternia, Undine represents one of the Greater Craymels, as one of the Primary Craymels of Infernia. The Water Craymel governs the use of all water element spells. Additionally, Undine herself can be summoned through the skill "Summon: Undine", but only when the Water Craymel is at MAX Vitality. When Undine appears, she strikes her staff onto the ground, creating a blast of water that damages enemies while healing the party.

In Tales of Symphonia, Undine is the first Summon Spirit that can be fought, granting Sheena Fujibayashi with a pact and spell summon, and the Aquamarine accessory. Sheena can summon Undine only while in Over Limit mode, at a cost of 100 TP. Once summoned, Undine summons several geysers that appear randomly on the field, similar to multiple Spread spells, while healing the members of the party.

As a cameo
Undine also appears as a cameo in other games. In the original Tales of Destiny, she 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). When she is summoned through the use of this item, Undine attacks in the same way she does in Tales of Phantasia, racing across the screen to hurt all enemies in her path.

Additionally, Undine makes a summoned cameo appearance in Tales of Destiny 2, through the Hi Ougi skill Aqua Rimms. This Hi Ougi is an extension to the spell Embrace End (localized in other games as Final Embrace), which can be used by Reala and Harold Belserius, and the optional boss Magnadeus. Undine calls forth a massive tidal wave that hits all enemies on the screen, then follows up by healing the party.

In 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 (Wednesday) within the world of Auldrant.

In Tales of Vesperia, the Entelexaia Belius is inadvertantly turned into a spirit while Rita is attempting to control Estelle's powers. The spirit has control of all waters, and asks Estelle to name her. Estelle promptly names the new spirit Undine.
