- Marco Rossi and Tarma Roving are the clearest hero starting points in the current roster reference.

- Character rankings should reflect story importance, recurring appearances, and gameplay identity.
Metal Slug Ultimate Collection Characters Overview
The current collection reference presents its cast through factions and recurring series roles rather than a single playable-character list. That distinction matters: a character may be central to the story, recognizable as a boss, or memorable as an NPC without being confirmed as a selectable fighter in every included title.
The announced compilation includes Metal Slug, Metal Slug 2, and Metal Slug X. Its listed additions include online co-op, online high-score tables, a revamped Combat School, and a museum with art and music galleries. These features make character recognition more useful for players comparing campaigns and revisiting the series timeline.
Video Highlights:
- The compilation’s title and presentation focus on the Metal Slug collection.
- The video provides a quick visual reference for the package’s arcade-action identity.
- Use it as a broad introduction rather than a confirmed roster source.
| Character group | Key names | Primary role |
|---|---|---|
| Heroes | Marco Rossi, Tarma Roving | Regular Army protagonists |
| Villains | Donald Morden, Allen O'Neil | Rebel Army opposition |
| NPCs | Hyakutaro Ichimonji, Rumi Aikawa | Supporting story roles |
| Factions | Regular Army, Rebel Army | Conflict framework |
Treat the character categories as a guide to narrative importance. The available collection details do not confirm that every named figure is playable in every included game.
Hero and Villain Rankings
For a practical character ranking, prioritize three factors: how strongly a figure defines the series conflict, how often the character returns, and how clearly the character represents Metal Slug’s military-comedy tone. This produces a useful hierarchy without inventing unconfirmed abilities or collection-exclusive mechanics.
| Rank | Character | Alignment | Why the character matters |
|---|---|---|---|
| 1 | Marco Rossi | Regular Army | Core hero and one of the most recognizable series figures |
| 2 | Donald Morden | Rebel Army | Central antagonist who defines the main military conflict |
| 3 | Tarma Roving | Regular Army | Established hero and key partner within the protagonist group |
| 4 | Allen O'Neil | Rebel Army | Recurring enemy figure with strong boss-character identity |
| 5 | Hyakutaro Ichimonji | Support | Important rescued character and recurring series presence |
| 6 | Rumi Aikawa | Support | Familiar NPC associated with the series’ mission flow |
Marco Rossi ranks first because he is the strongest shorthand for the Regular Army’s campaign identity. Tarma Roving follows closely as a core partner whose importance is best understood alongside Marco rather than in isolation.
Donald Morden is the most important villain for story context. His role gives the early campaigns a consistent opposing force, while Allen O'Neil offers a more direct combat-focused presence. Hyakutaro Ichimonji and Rumi Aikawa are valuable for understanding the series beyond its playable soldiers and bosses.
Marco Rossi
Role: Regular Army hero. Best reference point for understanding the collection’s main campaign perspective and military mission structure.
Tarma Roving
Role: Regular Army hero. A natural comparison point for players studying the partnership and recurring cast behind the mainline missions.
Donald Morden
Role: Rebel Army leader. The clearest antagonist to track when comparing the conflict across the included games.
These rankings describe narrative relevance and series recognition. They are not a tier list for damage, speed, weapons, or competitive performance.
Character Roles Across the Included Games
The collection’s confirmed game list creates a focused way to study the cast. Metal Slug 2 and Metal Slug X are especially useful to compare because X is a revamped version of Metal Slug 2. Players can therefore examine how the same broad character framework supports two related campaign experiences.
| Included title | Character-study focus | Best comparison |
|---|---|---|
| Metal Slug | Establishes the core Regular Army versus Rebel Army conflict | Marco, Tarma, Morden |
| Metal Slug 2 | Expands the mainline setting and recurring cast | Heroes, Morden, support figures |
| Metal Slug X | Revisits the Metal Slug 2 foundation as a revamp | Changes in presentation and campaign flow |
Use the following role map when reviewing screenshots, museum entries, or Combat School references:
- Protagonists: Marco Rossi and Tarma Roving anchor the Regular Army perspective.
- Opposition: Donald Morden represents the Rebel Army’s central threat.
- Combat rivals: Allen O'Neil is best tracked as a recurring enemy presence.
- Supporting figures: Hyakutaro Ichimonji and Rumi Aikawa add context around missions and rescues.
- Faction context: The Regular Army and Rebel Army explain why characters appear on opposing sides.
| Role | Questions to ask | Useful collection feature |
|---|---|---|
| Hero | How does this character represent the campaign viewpoint? | Museum art, campaign replay |
| Villain | What conflict does this figure establish? | Mission context, boss encounters |
| NPC | What story or rescue function does the figure provide? | Gallery entries, mission scenes |
| Faction | Which side frames the character’s actions? | Series history, art gallery |
Start with Metal Slug, then compare Metal Slug 2 and Metal Slug X. This keeps the character discussion tied to the collection’s currently listed titles.
Step-by-Step Character Research Guide
A character guide becomes more reliable when it separates confirmed collection details from broader series knowledge. Follow these steps to build a useful roster reference without treating every familiar Metal Slug figure as a confirmed playable option.
Start with the Confirmed Titles
Record Metal Slug, Metal Slug 2, and Metal Slug X as the current collection foundation. Do not assume that every mainline or spin-off game is included.
Sort Characters by Function
Place each name under hero, villain, NPC, or faction. This makes the roster easier to scan and avoids confusing a story character with a playable soldier.
Compare Recurring Roles
Track how Marco Rossi, Tarma Roving, Donald Morden, and Allen O'Neil frame the conflict across the included campaigns.
Use the Museum for Context
Check the planned art and music gallery for visual or historical details once the collection provides those entries. Treat gallery information as reference material, not a gameplay stat sheet.
Separate Fact from Expectation
Label confirmed features, series background, and personal rankings separately. This is especially important before the planned 2027 release.
Character Guide Checklist:
- Identify the character's faction or story role
- Confirm whether the name belongs to an included title
- Separate playable heroes from NPCs and villains
- Compare Metal Slug 2 with Metal Slug X
- Check official collection updates before release
| Research checkpoint | Reliable conclusion |
|---|---|
| Named hero | Strong series identity, but not automatic proof of collection-wide playability |
| Named villain | Useful for campaign structure and boss context |
| Named NPC | Story relevance without confirmed combat control |
| Unlisted game | Do not treat its characters as confirmed collection content |
A strong roster page states what is confirmed, what is inferred from the series, and what remains to be verified through future official updates.
