Naruto Shippuden:
Advance Ninja Showdown

What Is Naruto Shippuden: Advance Ninja Showdown?

The Naruto GBA RPG that the official games never gave us.

Naruto Shippuden: Advance Ninja Showdown is a fully completed GBA ROM hack of Pokémon FireRed, built by Naruzuna X and released in English. It takes the Pokémon formula — catch characters, build a team, train them up, challenge gyms, and face the Elite Four equivalent — and transplants it entirely into the world of Naruto Shippuden.

Every Pokémon in the game has been replaced with a shinobi from the series. Every move has been replaced with a jutsu. The overworld has been restyled to reflect Naruto's world, with locations renamed to match Hidden Village settings. Items have been renamed — the bicycle becomes Ninja Boots, Poké Balls become Kunai Scrolls — and the type chart has been adjusted to reflect elemental Chakra advantages from the anime (Wind is weak to Fire, Electric beats Earth, and so on).

The defining feature that sets it apart from most anime ROM hacks is its dual-version structure. The game ships as two separate experiences: the Ashura Version, where you begin your journey as Naruto, and the Indra Version, where you begin as Sasuke. Both versions share the same core map but feature completely different exclusive characters, story flavour, and team-building options — making it genuinely worth playing through twice if you want the full roster.

Ashura vs Indra: Choosing Your Path

Two versions, two completely different rosters and story perspectives.

This is the most important decision you will make before loading the game. Ashura and Indra are not just cosmetic differences — each version has characters that are entirely exclusive to it, and some of the most powerful ninja in the game are locked to one path or the other. Here is what each version offers:

Both versions also share a pool of catchable ninja across routes and the Safari Zone equivalent, so your exclusive starter characters are supplemented by common characters available in both runs. The Ninja Academy (Pewter City equivalent) is where you unlock special characters, and the Kamui Dimension — requiring an Obito who knows Kamui — is where you access the five Ninja Fusions.

What's In the Game

Everything Naruzuna X rebuilt for the Naruto universe.

---

The Shinobi Roster

70+ ninja from every major faction in Naruto Shippuden.

The roster pulls from nearly every major arc and faction across Naruto Shippuden, giving the game enormous breadth of characters. The Leaf Village provides your core team options from the start, but as you progress through the game you will encounter — and be able to recruit — ninja from the Akatsuki, Sand Village, Sound Village, and even reanimated Edo Tensei fighters from the Fourth Great Ninja War arc.

Plus 46+ additional characters across routes, the Safari Zone, the Ninja Academy, and post-game areas — including transformed forms of key characters counted separately in the roster.

Jutsu and the Type System

How the battle system has been rebuilt around Naruto's chakra mechanics.

Every standard Pokémon move in the game has been replaced with a jutsu — either an English or Japanese name pulled directly from the anime, with several Gen 7 techniques added alongside the classic Shippuden-era moves. The result is a battle system that feels like Naruto rather than Pokémon, even though the underlying engine is the same.

The type chart has been meaningfully adjusted to reflect the elemental chakra logic from the series. In the anime, Fire beats Wind, Wind beats Lightning, Lightning beats Earth, Earth beats Water, and Water beats Fire — Naruzuna X has adapted this into the game's advantage and weakness system, giving battles a distinct flavour compared to standard FireRed. Electric (Lightning) now has an advantage against Earth type, and Wind is weak against Fire type, among other changes.

Type Matchup	Advantage / Weakness	Source
Electric (Lightning)	Strong vs Earth	Raiton beats Doton
Wind (Flying)	Weak to Fire	Futon loses to Katon
Water	Beats Fire	Suiton beats Katon
Grass (Wood)	Beats Water and Earth	Mokuton dominance
Fight	Beats Dark	Taijutsu vs Genjutsu
Dark	Beats Ghost and Psychic	Genjutsu vs illusion

Ninja Fusions

Five special combinations hidden inside the Kamui Dimension.

One of the game's most unique features is its five Ninja Fusions — special merged characters that do not exist in the anime but are created specifically for this hack. To access them you need to progress to the point where you have an Obito who knows the Kamui technique, then find the Kamui Dimension portal. Inside, interacting with the stones unlocks each fusion.

• Narusake — the fusion of Naruto Uzumaki and Sasuke Uchiha. The ultimate Leaf Village combination, merging the Nine-Tails and Sharingan into one fighter.
• Hinakura — a fusion combining Hinata Hyūga and Sakura Haruno. Merges Byakugan precision with medical ninjutsu power.
• Jiroychi — the combination of Jiraiya and Orochimaru. Two Sannin in one fighter — contrasting styles fused into one powerhouse.
• Saidori — a fusion not found in the original anime, exclusive to this hack and available only after meeting certain in-game conditions.
• Kobashi — the fifth fusion, similarly exclusive to the game. A late-game reward for thorough explorers.

Known Bugs & Workarounds

An honest heads-up — this hack has rough edges worth knowing before you start.

Advance Ninja Showdown is a completed hack but not a polished one. The creator openly documented several bugs. None of them break the game entirely, but some require specific workarounds to avoid frustration mid-run:

• Transformation slot bug: Mega Evolution / Transformation only works in double battles if the transforming ninja is in the 2nd party slot. In single battles or from slot 1, the ninja may hit itself instead of the opponent.
• Always carry a spare ninja: The game frequently uses double battles. If you enter one with only a single healthy ninja, the game can crash. Keep at least two battle-ready shinobi in your party at all times.
• Pallet Village NPC bug: The NPC who clears your travel ticket in Pallet Village (the FireRed equivalent of Professor Oak's rival scene) can occasionally bug out. The documented fix is to rename your ROM file and reload.
• Partially untranslated text: Some move names and NPC dialogue remain in Portuguese or Spanish — the hack originated in a Portuguese-speaking community. The main story and menus are in English but expect occasional untranslated text lines.
• Random crashes are rare but real: Save frequently using both in-game saves and emulator save states. The creator advises this explicitly. Crashes are uncommon but can occur during longer sessions.
• Rival trigger in Ashura v1.5.7: In the most recent Ashura build, the rival fight at the start of the game does not always trigger correctly — he may not walk up to challenge you. This is a known issue in that specific version; the v1.02 build does not have this problem.

How Does It Hold Up?

An honest take on what works, what does not, and who it is for.

Advance Ninja Showdown is a game made with genuine love for the Naruto franchise. The dual-version structure is clever and gives it replay value that most anime ROM hacks lack — choosing between Naruto's and Sasuke's paths is a meaningful choice with real consequences for your roster and experience. The transformation system, even with its slot restriction bug, adds drama to fights in a way that a pure stat-replacement hack would not.

• The dual version concept is the real strength: Playing through as Naruto and then going back through as Sasuke genuinely feels like two different games, especially in the early and mid-game where your available roster diverges significantly.
• Roster variety is impressive for a 70+ character hack: Most anime hacks of this era have far fewer characters. The spread across Leaf, Akatsuki, Sand, Sound, and special forms means you always have options when building your team.
• The type chart changes add something: Adapting the chakra element system means fights require a different kind of thinking than standard FireRed — Wind's weakness to Fire changes a lot of route and gym matchups.
• The bugs are real and need managing: The transformation slot restriction is the most disruptive — until you know about it, hitting yourself instead of transforming in a key fight is genuinely confusing. Once you know, it is manageable, but it should have been fixed.
• Partial translation is noticeable: Players who do not read Portuguese will hit untranslated lines fairly regularly, particularly in move names and some NPC text. It does not prevent progression but does break immersion.
• Difficulty is genuine: This is not an easy hack. The trainer AI has been pushed up and some of the gym equivalents hit harder than you would expect from a first run. Coming in with the expectation of a challenge is the right mindset.

Good to Know Before You Start

Practical tips to make your ninja run as smooth as possible.

• Pick your version based on your favourite character, not just aesthetics: Ashura and Indra lock you out of each other's best characters. If you specifically want Itachi, Madara, or Orochimaru, you need Indra. If you want Minato, Jiraiya, or Bijuu Mode Naruto, go Ashura.
• Always keep two healthy ninja for double battles: The game does not warn you before forcing double battles. Running in with one healthy ninja and one fainted will crash the game. Keep your party stocked.
• Transformation goes in slot 2 for double battles: If you want to use a ninja's transformed form in a double battle, make sure they are in the second party slot — not the first. This is not explained anywhere in the game.
• Save with emulator save states, not just in-game saves: The in-game save is functional but occasional bugs mean it is worth having a save state backup. Use Shift + F1 through F10 on most emulators.
• The Ninja Academy is not optional: Special characters, including some of the strongest in the game, are unlocked through the Academy (Pewter City equivalent). Do not skip it thinking it is just the tutorial — revisit it as you progress.
• Get Obito before attempting the Kamui Dimension: You need an Obito that knows the Kamui technique to unlock the Fusion characters. Make sure Obito is in your party and has the move before going to the stones.
• Best for: Naruto Shippuden fans first, Pokémon fans second. If you love the anime and want to build a dream team of shinobi in an RPG format, this hits the brief well despite its rough edges.

Frequently Asked Questions

The most common questions before loading Advance Ninja Showdown.

What is Naruto Shippuden: Advance Ninja Showdown?

It is a completed GBA ROM hack of Pokémon FireRed by Naruzuna X. Every Pokémon has been replaced with a Naruto Shippuden shinobi (70+ in total), every move replaced with anime-accurate jutsu, and the game features two separate story paths — Ashura (Naruto) and Indra (Sasuke) — each with exclusive characters.

What is the difference between Ashura and Indra versions?

Ashura starts you as Naruto and gives access to characters like Minato, Jiraiya, Bijuu Mode Naruto, Pain, Konan, and the Four Kages. Indra starts you as Sasuke and gives access to Itachi, Orochimaru, Madara, Team Taka, Susanoo Mode, and the Sound Village ninjas. Both share common catchable characters but have completely different exclusive rosters.

How do I get the Ninja Fusions?

You need an Obito in your party who knows the Kamui technique. Find the Kamui Dimension (there is a portal linked to Obito's ability), enter it, and interact with the stones inside to unlock the five fusions: Narusake, Hinakura, Jiroychi, Saidori, and Kobashi.

Why is Mega Evolution / Transformation hitting itself?

This is a known bug. Transformation only works correctly in double battles when the transforming ninja is in the second party slot. In single battles, or from the first slot in doubles, the ninja may target itself. Move your transformer to slot 2 before fights where you plan to use it.

Is the game fully in English?

Mostly. The main story, menus, and most dialogue are in English. However, some move names and occasional NPC text remain in Portuguese or Spanish from the hack's original release. It is playable in English but expect some untranslated text.

Which version is more stable — v1.02 or v1.5.7?

For the Ashura path, v1.02 is generally considered the more stable build. The v1.5.7 update introduced a rival trigger bug at the start of the game where the rival does not always initiate the opening fight, which can affect progression. Unless you need specific v1.5.7 features, the v1.02 builds are recommended.

Can I play Naruto Shippuden Advance Ninja Showdown on mobile or in a browser?

Yes. As a GBA ROM hack it works through browser-based GBA emulators on desktop and mobile. You can play it directly here on RomHaven with no downloads or setup required.

Where do I find the Ninja Academy and how do I get special characters?

The Ninja Academy is located in Pewter City's equivalent on the map. You need to enter Diglett's Cave (renamed Snake Cave / Orochi Cave) — go down from the cave entrance, enter the building, and click on the statue inside. This is a commonly missed step. Once in the Academy, completing its challenges unlocks special characters not available in the wild.
