The concept of the Meta Liberation Army (MLA) expanding worldwide and infiltrating other countries presents a fascinating and terrifying "what if" scenario within the My Hero Academia universe. Based on the provided information, the foundational elements for such a global expansion are already present, making it a highly plausible, albeit catastrophic, development.

Foundations for Global Infiltration

The MLA, both in its original and refounded forms, possesses several inherent characteristics that would make worldwide infiltration highly effective:

Core Ideology: Universal Appeal (to some): The central philosophy of "free usage of Quirks is a basic human right and emphasizes liberation over regulation" resonates with a fundamental desire for freedom. In a world where Quirk discrimination and strict regulations exist, this message could find fertile ground in many countries. The original MLA "was large and powerful enough to oppose the governments of multiple countries for several years," indicating its ideology already had international reach or at least significant transnational appeal.

Leadership Structure & Influence (New MLA):

Corporate & Political Figures: The new MLA's leading members are "major figures in the corporate and political fields." This is their most potent infiltration tool. Individuals like Re-Destro (CEO of Detnerat Company), Skeptic (board member at Feel Good, Inc.), and Trumpet (leader of the Hearts and Mind Party) possess legitimate influence, wealth, and networks that extend far beyond Japan's borders.

Global Corporations: Large corporations often have international branches, subsidiaries, and business dealings. Detnerat, for instance, could have offices, factories, or partnerships in various countries, providing perfect cover for MLA cells to establish themselves.

Political Parties: While Trumpet's party is Japanese, the underlying concept of influencing political discourse and policy through a "liberation" ideology could be replicated or adapted in other nations.

Secrecy and Patience: The new MLA "rebuilt... from the shadows, spreading Destro's ideology and gaining followers while avoiding attracting the attention of the authorities. By remaining in the shadows for decades, the Meta Liberation Army has amassed loyal warriors across many generations." This long-term, clandestine approach is ideal for slow, deep infiltration globally.

Dedicated Warriors: The "rank and file members of the army are known to be zealously dedicated to their cause." This fanaticism means they are willing to go to extreme lengths, including self-sacrifice, for the MLA's goals, making them reliable agents for covert operations abroad.

Propaganda and Recruitment: Destro's autobiographical book, Meta Liberation War, became a bestseller with "several reprints due to its popularity." This book, containing the core ideology, could easily be translated and disseminated globally, acting as a powerful recruitment tool and ideological foundation for new cells. Skeptic, as an executive director of a publishing company, would be adept at this.

"Liberated Districts": The concept of "liberated districts" like Deika City, where the majority of residents align with the MLA, could be replicated on a smaller scale in various countries, starting as seemingly innocuous communities or business hubs before revealing their true nature.

How Worldwide Infiltration Would Occur

If the MLA were to go global, the infiltration would likely follow a multi-pronged strategy:

Economic & Political Entry Points:

Corporate Expansion: Detnerat and other MLA-controlled businesses would expand internationally, establishing legitimate operations that serve as fronts for MLA activities. Key MLA members would be placed in leadership positions within these international branches.

Lobbying & Influence: Using their corporate and political connections, MLA members would subtly lobby for deregulation of Quirks, support politicians sympathetic to their cause, and fund research that aligns with their "liberation" narrative.

Financial Networks: Their wealth would allow them to establish complex international financial networks to fund operations, pay agents, and launder money, making them difficult to track.

Ideological Spreading:

Digital & Media Campaigns: Leveraging Skeptic's media expertise, they would launch sophisticated online campaigns, create "think tanks," and publish articles or documentaries promoting Quirk liberation, often subtly at first, then more overtly.

Underground Cells: Dedicated MLA followers would establish small, clandestine cells in various countries, recruiting individuals who feel marginalized or oppressed by Quirk regulations. These cells would operate independently but be loosely coordinated by central leadership.

Exploiting Local Grievances: They would identify and exploit existing social tensions, discrimination, or government overreach related to Quirks in different nations, positioning themselves as the solution or the voice of the oppressed.

Recruitment & Training:

Identifying "Warriors": They would seek out individuals with powerful Quirks who feel stifled, or those with a strong sense of injustice, offering them a "place to belong" and a cause.

Covert Training Facilities: Secret training grounds, perhaps disguised as corporate retreats or remote research facilities, would be established to hone the Quirks of new recruits and instill the MLA's fanatical dedication.

"Meta Abilities" Focus: The emphasis on strengthening "Meta Abilities" would be a global selling point, attracting those who wish to maximize their power without societal constraints.

Intelligence & Counter-Intelligence:

Global Surveillance: Skeptic's abilities and the MLA's resources would be used to gather intelligence on international hero agencies, governments, and anti-Quirk movements.

Infiltration of Agencies: They might attempt to place moles within hero organizations, police forces, or intelligence agencies in various countries to gather information and disrupt counter-MLA efforts.

Potential Global Impact

A worldwide MLA would have catastrophic consequences:

Widespread Anarchy: The core goal of "liberation over regulation" would lead to a breakdown of law and order as individuals are encouraged to use their Quirks without restraint, resulting in increased collateral damage and civilian casualties.

International Conflict: Governments would likely clash over how to handle the MLA, potentially leading to proxy wars or direct conflicts between nations supporting or opposing the MLA's ideology.

Erosion of Hero Society: The very foundation of hero society, which relies on regulation and order, would be severely undermined. Public trust in heroes and governments would plummet.

Rise of "Meta-Human" Supremacy: While promoting "liberation," the MLA's underlying philosophy could easily devolve into a form of Quirk supremacy, where those with powerful Quirks dominate and oppress the Quirkless or those with weaker abilities.

Economic Collapse: The disruption caused by widespread Quirk usage and conflict would cripple global economies, leading to resource shortages and humanitarian crises.

New Villains: The MLA's ideology would inspire countless new villains and rogue Quirk users, further exacerbating the global crime rate.
