此擴充包收錄眾多人氣角色，包括「月亮伊布V」「仙子伊布V」「火伊布V」「水伊布V」「雷伊布V」「太陽伊布V」「葉伊布V」以及「冰伊布V」等，每張卡牌皆以伊布進化型為主題。此外，包內亦包含其他強力寶可夢，如「伊布」「炎帝」「頑皮雷彈」「長毛巨魔」「花潔夫人」「瑪夏多」「巨沼怪」「噬沙堡爺」「索羅亞克」等，為玩家提供多樣的戰略組合選擇。整個擴充包共包含101張卡牌，並首次於2021年5月28日在日本發行，隨後於2021年6月11日在台灣與香港、6月25日在泰國、8月11日在韓國，以及10月1日在印尼陸續上市。中文、泰文及印尼語版本還同時推出「進化 V 初學者組牌套裝」。

除了基本卡牌之外，《伊布英雄》亦附有大量支援特定伊布進化型的訓練家卡牌，其中部分卡牌支援「單擊風格」（Single Strike）或「疾擊風格」（Rapid Strike）等遊戲機制，使策略運用更為靈活。同一天發售的產品還包含未納入此擴充包的伊布進化型 Pokémon VMAX 版本。

在日本與韓國的版本中，每包卡牌還隨附一張「寶可夢卡牌謎題卡」（Japanese: ナゾトキ ポケカ; Korean: 포켓몬 카드 수수께끼），作為官方活動的一部分。日本版提供十張謎題卡，每張都有編號；韓國版則提供七張未編號的卡片。日本版卡片背面附有解答提示及活動專屬 QR Code，韓國版則提供官方韓國 Pokémon TCG YouTube 頻道的 QR Code。這些謎題卡的設計與官方網站密切配合，玩家可透過線上平台查看提示、選項與解答，進行分階段挑戰，並完成最終關卡後參加抽獎，有機會贏得「伊布翻轉牌組收納盒」。

由於 COVID-19 疫情期間 TCG 的人氣大幅提升，日本版本《伊布英雄》發售時需求遠超預期。5月7日於 Pokémon Center Online 開放預購後，擴充包、伊布進化型組合套裝、VMAX 特別組及高級雙盒組等產品迅速售罄。據推測，部分預購的搶購潮由海外團體透過軟體代理程式操作，促使寶可夢公司於5月12日發表聲明，對未能成功預購的玩家致歉，並承諾將優先安排生產最熱門產品。同日，官方還說明短期內產品發售的因應措施，包括 Pokémon Center Online 限量銷售以及透過抽籤系統處理後續預購。抽籤申請期間為5月14日至18日，抽中者於5月27日後獲通知，預購於5月7日完成者則於正式發售日收貨，不參與抽籤；抽籤預購則預計於6月至7月中旬陸續送達。

整體而言，《伊布英雄》不僅以完整的伊布進化型卡牌系列滿足玩家收藏與策略需求，也藉由創新的謎題卡活動及 VMAX 特別組合，為寶可夢 TCG 劍&盾系列注入新鮮活力，並成功在亞洲市場引發熱烈反響。

The Enhanced Expansion Pack: Eevee Heroes (Japanese: 強化拡張パック「イーブイヒーローズ」) is the second enhanced expansion released for the Traditional Chinese version of the Pokémon Trading Card Game (TCG) Sword & Shield series, and the fifth enhanced expansion in the Japanese Sword & Shield series. This expansion centers on Eevee and its various evolutions, continuing the refined design of the Sword & Shield era, and highlights the Pokémon V cards of all eight Eevee evolutions from Generation VIII.

The expansion features numerous popular cards, including “Moon Eevee V,” “Fairy Eevee V,” “Fire Eevee V,” “Water Eevee V,” “Lightning Eevee V,” “Sun Eevee V,” “Leaf Eevee V,” and “Ice Eevee V,” each themed around a specific Eevee evolution. In addition, it contains other powerful Pokémon such as Eevee, Entei, Pincurchin, Oranguru, Florges, Marshadow, Swampert, Sandaconda, and Zoroark, providing players with diverse strategic options. The entire set includes 101 cards and was first released in Japan on May 28, 2021. It was subsequently released in Taiwan and Hong Kong on June 11, 2021, in Thailand on June 25, 2021, in South Korea on August 11, 2021, and in Indonesia on October 1, 2021. The Chinese, Thai, and Indonesian releases were also accompanied by an Evolution V Starter Deck.

Beyond the basic Pokémon cards, Eevee Heroes also includes a variety of Trainer cards that specifically support certain Eevee evolutions, some of which are compatible with the Single Strike or Rapid Strike mechanics, enhancing strategic gameplay. On the same release date, products featuring Pokémon VMAX versions of the Eeveelutions not included in the expansion were also made available.

In both the Japanese and Korean versions, each booster pack contained a “Pokémon Card Puzzle” card (Japanese: ナゾトキ ポケカ; Korean: 포켓몬 카드 수수께끼) as part of an official promotional event. The Japanese version included ten numbered puzzle cards, while the Korean version included seven unnumbered cards. The Japanese cards featured answer hints and a campaign-specific QR code on the reverse side, while the Korean cards included a QR code linking to the official Korean Pokémon TCG YouTube channel. These puzzle cards were closely integrated with the official website, allowing players to view hints, multiple-choice answers, and solutions online, progressing through multiple stages of challenges. Completing the final stage allowed players to enter a lottery for a chance to win an “Eevee Flip Deck Case.”

During the COVID-19 pandemic, the popularity of the TCG surged, and the Japanese release of Eevee Heroes experienced overwhelming demand. After pre-orders opened on May 7, 2021, through Pokémon Center Online, the expansion, Eeveelution Set, VMAX Special Set, and High-Class Double Box sold out rapidly. It was speculated that part of the surge in pre-orders was driven by overseas groups using automated software, prompting The Pokémon Company to issue a statement on May 12, apologizing to players who were unable to secure pre-orders and pledging to prioritize production of the most popular products. On the same day, the company also announced short-term measures for sales, including limiting certain products to Pokémon Center Online and processing additional pre-orders via a lottery system. The lottery application period ran from May 14 to 18, with winners notified after May 27. Pre-orders placed on May 7 were delivered on release day and were not part of the lottery; lottery pre-orders were scheduled for delivery between mid-June and mid-July.

Overall, Eevee Heroes not only satisfies collectors and players with a complete lineup of Eevee evolution cards, but also injects fresh excitement into the Sword & Shield series through innovative puzzle card activities and VMAX special sets, achieving strong popularity across the Asian market.
