Quick Guide
  • Metal Slug Ultimate Collection characters span heroes, villains, factions, and supporting NPCs.
  • Marco Rossi and Tarma Roving are the clearest hero starting points in the current roster reference.
  • Donald Morden and Allen O'Neil represent the central Rebel Army opposition.
  • Included games currently cover Metal Slug, Metal Slug 2, and Metal Slug X.
  • 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.

Reading the Roster

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.

RankCharacterAlignmentWhy the character matters
1Marco RossiRegular ArmyCore hero and one of the most recognizable series figures
2Donald MordenRebel ArmyCentral antagonist who defines the main military conflict
3Tarma RovingRegular ArmyEstablished hero and key partner within the protagonist group
4Allen O'NeilRebel ArmyRecurring enemy figure with strong boss-character identity
5Hyakutaro IchimonjiSupportImportant rescued character and recurring series presence
6Rumi AikawaSupportFamiliar 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.

Ranking Limits

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 titleCharacter-study focusBest comparison
Metal SlugEstablishes the core Regular Army versus Rebel Army conflictMarco, Tarma, Morden
Metal Slug 2Expands the mainline setting and recurring castHeroes, Morden, support figures
Metal Slug XRevisits the Metal Slug 2 foundation as a revampChanges 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.
RoleQuestions to askUseful collection feature
HeroHow does this character represent the campaign viewpoint?Museum art, campaign replay
VillainWhat conflict does this figure establish?Mission context, boss encounters
NPCWhat story or rescue function does the figure provide?Gallery entries, mission scenes
FactionWhich side frames the character’s actions?Series history, art gallery
Best Comparison Method

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.

1

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.

2

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.

3

Compare Recurring Roles

Track how Marco Rossi, Tarma Roving, Donald Morden, and Allen O'Neil frame the conflict across the included campaigns.

4

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.

5

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 checkpointReliable conclusion
Named heroStrong series identity, but not automatic proof of collection-wide playability
Named villainUseful for campaign structure and boss context
Named NPCStory relevance without confirmed combat control
Unlisted gameDo not treat its characters as confirmed collection content
Editorial Standard

A strong roster page states what is confirmed, what is inferred from the series, and what remains to be verified through future official updates.
