無極汰那（Eternatus）是《寶可夢》系列中極具代表性的傳說寶可夢之一，也是截至第八世代為止，在設定上擁有最高種族值總和紀錄的特殊存在。牠不僅在數值設計上突破系列傳統，更在世界觀中扮演核心角色，被視為伽勒爾地區所有「極巨化」與「超極巨化」現象的能量源頭，是劇情與系統設定高度結合的關鍵寶可夢。

無極汰那首次登場於Nintendo Switch遊戲《寶可夢 劍／盾》，其形象融合外星生命與能量生命體的概念，整體設計呈現骨架般的細長結構與強烈的紫紅色能量光芒，象徵其不穩定且近乎無限的力量來源。在遊戲設定中，牠並非單純的傳說寶可夢，而是一個來自遠古隕石的存在，於數千年前降臨伽勒爾，並引發被稱為「闇夜（Darkest Day）」的巨大災難。

在能力數值方面，無極汰那之所以備受討論，主要源自其特殊的「無極巨化（Eternamax）」形態。當進入此形態時，其種族值總和高達1125，遠遠超越一般傳說寶可夢常見的680至720區間，甚至超過多數歷代最強神獸，被視為目前官方設定中的數值頂點。其能力分布極端而誇張：HP高達255，防禦與特防皆為250，使其幾乎難以被擊倒；攻擊為115、特攻125，兼具輸出能力；速度則達130，確保在戰鬥節奏上仍具壓制力。這樣的配置使無極巨化形態在劇情中呈現近乎「不可戰勝」的定位。

然而，這個驚人的1125種族值並非玩家可自由使用的戰力。無極巨化形態僅存在於《寶可夢 劍／盾》的主線最終戰，是劇情專用的Boss形態，玩家在一般遊戲流程、對戰模式或官方競技環境中皆無法使用。這項限制顯示開發團隊刻意將其設計為世界觀象徵，而非破壞對戰平衡的實戰角色。

玩家實際能夠捕捉與培育的，是無極汰那的「通常形態」。該形態的種族值總和為690，屬於毒屬性與龍屬性的複合寶可夢，在傳說寶可夢之中仍屬高水準強度。其專屬招式與高速度定位，使其在對戰環境中具有明確的進攻與壓制特色，但仍維持在可平衡的範圍內。

從劇情層面來看，無極汰那被設定為伽勒爾地區能量循環的根源。極巨化現象所需的「極巨能量」正是由牠釋放而來，洛茲委員長試圖利用其力量解決能源危機，卻反而再次引發災難，形成遊戲主線的核心衝突。因此，無極汰那同時象徵科技依賴與能源失控的隱喻，也是第八世代敘事主題的重要象徵。

整體而言，無極汰那之所以特別，不僅因為其創下系列最高種族值紀錄，更在於它代表《寶可夢》首次將「數值極限」與「世界觀核心設定」完全結合的設計思路。牠既是劇情中的終極威脅，也是伽勒爾文明運作的基石，使其成為第八世代最具標誌性的傳說寶可夢之一。

Eternatus is one of the most iconic Legendary Pokémon in the Pokémon series and, as of Generation VIII, holds the record for the highest total base stats ever established in official lore. Beyond its extraordinary numerical design, it also plays a central role in the worldbuilding, serving as the fundamental energy source behind the Dynamax and Gigantamax phenomena in the Galar region. As a result, Eternatus represents a rare case where gameplay mechanics and narrative setting are deeply integrated.

Eternatus first appeared in Pokémon Sword and Shield on the Nintendo Switch. Its design blends elements of an extraterrestrial organism and a living energy entity, featuring a skeletal, elongated structure surrounded by intense crimson-purple energy. This appearance reflects its unstable and seemingly limitless power. According to the game’s lore, Eternatus is not merely a traditional Legendary Pokémon but an ancient being that arrived on a meteor thousands of years ago, triggering a catastrophic event known as the “Darkest Day.”

What makes Eternatus especially notable is its unique “Eternamax” form. In this state, its total base stat value reaches an unprecedented 1125, far exceeding the typical Legendary Pokémon range of 680–720 and surpassing nearly all previously known powerhouse Pokémon. Its stat distribution is extremely exaggerated: 255 HP, 250 Defense, and 250 Special Defense make it extraordinarily difficult to defeat, while 115 Attack and 125 Special Attack provide substantial offensive capability. With a Speed stat of 130, it also maintains strong battlefield control. This configuration reinforces its portrayal in the story as an almost unbeatable entity.

However, this overwhelming 1125 base stat form is not usable by players in normal gameplay. The Eternamax form appears exclusively during the main story’s final battle as a narrative boss encounter. Players cannot access or use this form in standard gameplay, competitive battles, or official formats. This restriction demonstrates the developers’ intention to present Eternatus primarily as a symbolic narrative force rather than a balance-breaking competitive character.

The version that players can actually capture and train is Eternatus’s standard form. This form has a total base stat value of 690 and possesses a dual Poison/Dragon typing, placing it among high-tier Legendary Pokémon in terms of strength while remaining balanced for gameplay. Its signature moves and high Speed stat allow it to function effectively as an offensive and pressure-oriented combatant without disrupting competitive balance.

From a narrative perspective, Eternatus is portrayed as the origin of the Galar region’s entire energy ecosystem. The Dynamax energy used throughout the region is generated by it, and Chairman Rose’s attempt to harness this power to solve an energy crisis ultimately triggers another disaster, forming the central conflict of the story. In this way, Eternatus symbolizes both technological dependence and the dangers of uncontrolled energy exploitation, making it a thematic centerpiece of Generation VIII’s storyline.

Overall, Eternatus stands out not only because it holds the highest base stat record in the franchise but also because it represents one of the series’ most ambitious design philosophies—combining numerical extremity with deep narrative significance. It functions simultaneously as the ultimate threat within the story and the foundation of Galar’s civilization, securing its place as one of the most defining Legendary Pokémon of the eighth generation.
