《超人王霸丸 光之國使者》（日文：ウルトラマン 光の国の使者）是萬代（Bandai）於2001年6月21日在WonderSwan Color（WSC）推出的格鬥動作遊戲。雖然它名義上是街機與SFC名作《ウルトラマン》的重製版，但因為大量內容經過重新調整，整體呈現方式與系統已幾乎是另一款新作。為了紀念圓谷英二誕生100週年，開發團隊特別在WSC的硬體限制下盡可能重現原作的魅力，從開場動畫到背景音樂、角色動作、語音演出，都展現相當高的製作誠意，尤其是各個怪獸與超人的動作細節，更能看出開發團隊的投入程度。當時預購還附贈「超人力霸王 vs. 巴爾坦星人」的精緻立體場景，讓收藏玩家非常驚喜。

戰鬥規則延續傳統格鬥動作形式，但設計上更重視重現《超人力霸王》特攝作品的節奏與演出效果。戰鬥中如果使用必殺技將敵人HP歸零即可直接獲勝；反之若以一般攻擊擊倒對手，怪獸會進入暈眩狀態，玩家必須趁此追加攻擊或等倒地倒數結束才能取得勝利。操作上使用A、B進行近身格鬥，搭配X可變換性能；Y專用於釋放必殺技，而與敵人貼身時則可進行投技。當對手倒地時還能使用特定指令進行壓制攻擊，使整體戰鬥節奏更貼近特攝作品的動作風格。必殺技需要累積專用能量槽，透過時間經過或命中攻擊來增加，必須在攻守之間作出判斷。

主要模式是「故事模式」，玩家操控的當然是初代超人力霸王。流程遵循TV版的基本架構：簡短劇情導入、科特隊作戰會議、怪獸出現、隨後超人力霸王登場對戰。雖然劇情被大幅濃縮，但仍保留不少原作粉絲才會注意的細節，例如怪獸出現時的資料介紹、簡易演出鏡頭，以及穿插的「群組分鏡Cut（ぐんぐんカット）」。事件場景也採用科特隊隊員的實拍照片拼貼，讓玩家在掌機上也能感受到濃厚的昭和特攝味。對戰中還會根據原作觸發特殊事件，例如把內隆嘎摔飛時不小心破壞發電所、或打敗加美拉後必定觸發「超人水流」結束戰鬥等，讓原作迷感到相當驚喜。此外，故事模式還設有「超人力霸王指數」評分系統，會根據玩家戰鬥表現、以及是否使用對應原作的必殺技作結，給予不同評價。

同時也具備對戰模式，但需要特定對戰卡才能進行，可自由選擇超人或怪獸互相對決，也支援通信對戰。另一大特色是「育成模式」，能培養六名角色，包括超人力霸王、巴爾坦星人、偽超人力霸王、梅菲拉斯星人、澤頓，以及一名隱藏角色。培養方式是透過戰鬥累積經驗值，再提升角色的拳力、腳力等能力，並能將培育角色帶到對戰模式使用或與朋友交換，使掌機遊戲的可玩性大幅提高。

角色陣容忠實再現初代作品，包括超人力霸王、貝姆拉、巴爾坦星人、內隆嘎、安特拉、紅王、加博拉、偽超人、凱姆拉、加米拉、哥莫拉、梅菲拉斯星人與澤頓，每隻怪獸都依原作設定打造專屬攻擊與特殊行動。像貝姆拉有著驚人的熱線速度、安特拉的磁力光線可以把敵人吸過來、哥莫拉擁有高等級超級護甲、梅菲拉斯星人的動作自由度極高，而澤頓則擁有強力的反擊光束。超人力霸王本身則具備完整再現的必殺技，例如斯派修姆光線、八分光輪與反射屏障「反彈光線」等，甚至連斯派修姆光線完整流動的動畫演出也忠實呈現，對當時的掌機作品來說非常罕見。

在市場評價方面，《超人王霸丸 光之國使者》雖然受限於WSC的硬體性能，無法展現大型平台的華麗畫面，但其對特攝粉絲需求的理解極為精準，重現度高、操作紮實、劇情演出充滿昭和氛圍，因此在《超人力霸王》粉絲群中獲得極佳口碑。許多玩家認為本作是WSC時期少數真正呈現高完成度的動作遊戲之一，特別是動畫演出與角色動作細節，即使在今日重新回看仍具魅力。雖然販售量因平台受限而未達主流市場，但在收藏界被視為值得入手的佳作，也是初代超人力霸王遊戲改編中相當有誠意的代表作。

“Ultraman: Messenger of the Land of Light” (Japanese: ウルトラマン 光の国の使者) is a fighting action game released by Bandai for the WonderSwan Color (WSC) on June 21, 2001. Although it is nominally a remake of the classic arcade and Super Famicom title Ultraman, a large portion of its content was reworked, making the overall presentation and system feel almost like an entirely new game. To commemorate the 100th anniversary of Eiji Tsuburaya’s birth, the development team strived to recreate the charm of the original within the limitations of the WSC hardware. From the opening animation to background music, character movements, and voice cues, the game displays remarkable craftsmanship, especially in the detailed animations of each Ultra Hero and monster. Players who pre-ordered the game even received a special diorama featuring “Ultraman vs. Baltan,” which greatly delighted collectors.

The battle system follows traditional fighting-action mechanics but places stronger emphasis on replicating the pacing and dramatic style of the Ultraman tokusatsu series. If the player defeats an enemy with a special move, the fight ends immediately. However, defeating the opponent with regular attacks only puts the monster into a stunned state—players must follow up with additional strikes or wait for the downed countdown to finish in order to claim victory. The A and B buttons are used for close-range combat, X changes performance modes, while Y triggers special moves. When close to the enemy, players can also perform throws. Certain commands can be used to execute ground-pressure attacks when the enemy is knocked down, further reinforcing the game’s tokusatsu-like action rhythm. Special attacks require building a dedicated gauge, which increases over time or when landing hits, forcing players to balance offense and defense.

The primary mode is Story Mode, in which the player controls the original Ultraman. The progression follows the basic structure of the TV series: a brief story introduction, Science Patrol briefing, monster appearance, and finally Ultraman entering battle. Although the plot is heavily condensed, many small details beloved by fans remain intact, including monster data screens, simple cinematic cuts, and the signature “Gungun Cut” transitions. Event scenes incorporate collaged photos of actual Science Patrol actors, giving the handheld title a strong Showa-era tokusatsu flavor. Special events from the original series also occur during battles, such as accidentally destroying a power plant when throwing Neronga, or triggering the “Ultra Water Stream” finishing animation after defeating Gamila. Story Mode also includes the “Ultraman Index,” a rating system that evaluates the player’s performance and rewards them for finishing battles with accurate, series-faithful special moves.

The game also includes a Versus Mode, which requires a dedicated battle card to unlock. Players can freely choose Ultramen or monsters to fight against each other, and the mode supports link-cable multiplayer. Another major feature is the Training Mode, which allows players to raise six characters: Ultraman, Alien Baltan, Fake Ultraman, Alien Mefilas, Zetton, and a hidden character. Characters gain EXP through battles, improving attributes such as punch power and kick power. Trained characters can be used in Versus Mode or traded with friends, greatly enhancing replay value for a handheld title.

The character roster faithfully recreates the original series, including Ultraman, Bemlar, Alien Baltan, Neronga, Antlar, Red King, Gabora, Fake Ultraman, Kemular, Gamila, Gomora, Alien Mefilas, and Zetton—each featuring their own unique attacks and actions based on the official lore. Bemlar boasts high-speed heat rays, Antlar can pull enemies in with magnetic beams, Gomora has powerful super armor, Mefilas offers exceptional action freedom, while Zetton wields devastating counter-beams. Ultraman himself comes with fully recreated signature moves such as the Specium Ray, Ultra Slash, and Reflective Barrier, with even the complete animation of the Specium Ray faithfully reproduced—something extremely rare for handheld games of that era.

In terms of reception, “Ultraman: Messenger of the Land of Light” was highly praised among tokusatsu fans despite the WSC’s limited hardware capabilities. Its faithful recreation of the Ultraman atmosphere, solid gameplay, and rich Showa-era presentation earned it a strong reputation within the fan community. Many consider it one of the most polished action titles available on the WonderSwan Color, with its animation quality and attention to detail remaining impressive even today. Although sales were modest due to the platform’s limited reach, the game is regarded in collector circles as a hidden gem—and one of the most earnest and lovingly crafted adaptations of the original Ultraman ever produced.
