Background / History

Dianxi is the princess of the Diamond Kingdom, and her formal manners in speech and dining reflect her royal upbringing. She is also stated to be the only Pokémon capable of creating Eternal Diamonds. 4

She becomes Qiao Ran's partner before his school Adventurer Battle. Although Qiao initially misrepresents her as a weak wild Pokémon, Dianxi proves herself by enduring Garchomp's opening Dragon Pulse and defeating it with successive Moon Power attacks. Their first major victory begins a special bond between trainer and Pokémon. 4 5

Qiao later entrusts Dianxi with teaching Vulpix human language and proper etiquette, recognizing her maturity and princess-like upbringing. 6

Appearance

In her standard form, Dianxi is a tiny, sparkling Pokémon with a dress-like body, a prominent pink diamond, and a refined princessly bearing. She is exactly 0.7 meters tall, allowing her to compete under Longjiang Gym's Young Beast Battle rules. 8 10

• Her Diamond Storm manifests as a swirling storm of pink diamond fragments. 9
• Her normal form is built for durability rather than agile movement. 9
• In Mega form, her skirt extends to her ankles, pink diamonds form the hemline, white ribbons trail from her head, and she floats in the air. 17
• Her first human form is a maiden with long deep-purple hair, rose-red eyes, and a white Bride Attire adorned with pink diamonds. 18
• When her Mega power dissipates, she regresses into a much younger, smaller human form. 18 19

Personality

Dianxi is dignified, conscientious, and proud of her status as a princess. She readily accepts responsibility for Vulpix's education and takes initiative in helping Qiao complete his capture tasks. 6 23

Her pride is especially apparent when Shi Yiyi criticizes Qiao Ran's performance preparation. Rather than retreating, Dianxi rejects the criticism, resolves to prove their worth, and triggers her Mega Evolution onstage. 17

She is deeply attached to Qiao Ran and places great value on being useful to him and receiving his approval. She is also sensitive about her smaller human form and does not want her princessly dignity undermined by being treated as a child. 19 23

Abilities & Skills

Diamond Physiology

Dianxi possesses exceptional natural durability, functioning as Qiao Ran's primary defensive Pokémon.

• Her normal form has base defenses of 150 in both defensive stats. 9
• She withstands Pangding's powerful Rollout collision despite its fourfold type advantage. 9
• She blocks attacks from two Mightyena that are eleven levels above her, relying on her defenses and Fairy typing to endure. 13
• Her mineral body is comparatively slow and poorly suited to evasive movement. 9
• Steel-type attacks are a serious weakness; an Excadrill's Iron Head leaves her unable to continue after their clash. 33

Moon Power

Dianxi's Moon Power is a powerful Fairy-type finishing move.

• It receives a same-type attack bonus and deals doubled damage against Dragon-type opponents. 4
• She uses repeated Moon Power attacks to defeat Chang Mengda's Garchomp. 4
• She combines Moon Power with Diamond Storm to wear down and defeat Long Jiangxue's Pangding. 9 10

Diamond Storm and Gem Techniques

Dianxi's signature Diamond Storm creates a wide-ranging storm of pink diamonds.

• Its broad coverage makes it difficult for opponents to evade. 32
• She uses it in battle against Pangding and Mawile. 9 32
• In Mega form, Diamond Storm's speed more than doubles, overwhelming Mawile. 32
• She incorporates Diamond Storm, Power Gem, and Dazzling Gleam into visually captivating stage performances. 16 17
• She can construct a gem barrier to shield Qiao Ran from Nihilego's venom. 39
• Diamonds created for ordinary attacks disperse afterward and are distinct from Eternal Diamonds. 32

Earth Power

Earth Power is Dianxi's principal answer to Steel-type opponents.

• Qiao Ran saves the move specifically to counter Iron Maiden's Excadrill and its Sandstorm strategy. 32 33
• The attack restricts Excadrill's movement and eventually lands a direct hit. 33
• Dianxi also uses Earth Power against poachers and Nihilego. 36 39

Mega Evolution

Dianxi can Mega Evolve when her will resonates with Qiao Ran through her Evolutionary Stone.

• The transformation requires a strong trainer–Pokémon bond and Qiao Ran's Key Stone connection. 17
• Mega Evolution raises her total base stats by 100 points, bringing them to 700. 4 32
• Her normal defensive distribution shifts into 160 base Attack and 160 base Special Attack. 32
• Her Speed rises from 50 to 110, eliminating her usual sluggishness. 32
• The form is temporary and imposes a heavy physical burden on Qiao Ran. 18 33

Eternal Diamond Creation

As the Diamond Princess, Dianxi can create Eternal Diamonds—gems that do not disperse like her ordinary battle diamonds.

• She first creates an Eternal Diamond in the form of a pink ring for Qiao Ran after Mega Evolving. 17
• She intends the ring to be preserved by Qiao Ran, and he promises to care for it. 17
• Creating an Eternal Diamond requires effort and is not something she uses casually in combat. 32

Human Form and Speech

Dianxi gains human speech immediately upon her first human transformation.

• Her initial transformation occurs directly after the Zhenhui Town competition. 18
• Her human form is linked to her Mega power and initially proves unstable when that power expires. 18
• She later travels in her smaller human form after receiving clothes selected by Qiao Ran. 19

Telepathy

Dianxi can relay thoughts telepathically.

• As a Legendary Pokémon, she is capable of psychic communication even though Qiao Ran's thoughts normally reach his Pokémon directly. 35
• Qiao uses her telepathy to contact Dr. Lilia during the poacher attack. 35
• Dianxi privately communicates a request to Qiao Ran through telepathy after he tests Tokiwa Power on her. 44

Created Items

• Eternal Diamond ring — Dianxi's first Eternal Diamond, created during her Mega Evolution and given to Qiao Ran. 17

Relationships

• Qiao Ran — Her trainer and “Master.” Their mutual trust enables her Mega Evolution; she fights protectively for him, performs alongside him, and values his approval deeply. 5 17 39
• Vulpix — A younger teammate whom Dianxi teaches etiquette and human language. Dianxi sometimes becomes jealous of Vulpix's closeness with Qiao Ran. 6 22
• Suicune — A fellow member of Qiao Ran's team. Dianxi practices performances with Suicune and later fights beside her against Nihilego. 15 39
• Long Jiangxue — Gym challenger and admirer who becomes intensely interested in Dianxi after their battle and wants to catch one herself. 9 10
• Shi Yiyi — Performance judge whose criticism provokes Dianxi's determination and catalyzes her first Mega Evolution. 17 18
• Eve — Qiao Ran's traveling companion who is eager to meet Dianxi and is captivated by her Mega form. 32
• Iron Maiden — Opposing Gym Leader whose Mawile and Excadrill face Dianxi during the Jinling Gym challenge. 32 33
• Dr. Lilia — Researcher contacted through Dianxi's telepathy during the poacher ambush. 35
