Learn how to unlock Metal characters in Injustice Mobile, farm Nth Metal and Valorium Alloy, unlock Dark Power specials, and upgrade powerful fighters like Batman Ninja Catwoman and The Merciless.
Metal characters are some of the most powerful cards in Injustice: Gods Among Us Mobile. Fighters such as Batman Ninja Catwoman, Batman Ninja Nightwing, The Merciless, The Batman Who Laughs, Shazam/New 52, and Black Adam/New 52 can become extremely powerful when properly promoted and upgraded. However, unlocking them is only the beginning. You also need Nth Metal for packs, Power Credits for upgrades, and Valorium Alloy from Phantom Zone to develop their special abilities. This guide explains how to unlock Metal characters, which Nth Metal packs to consider, how Metal promotions work, how Dark Power specials are upgraded, and how to build a stronger Metal team.
Metal characters are a special character tier in Injustice Mobile with unique passive abilities and Dark Power mechanics. They are obtained differently from standard Bronze, Silver, and Gold characters and require Nth Metal-based packs or other applicable rewards. Because Metal cards have their own progression system, collecting one is only the first step toward maximizing its potential.
The Metal roster includes fighters such as Batman Ninja Catwoman, Batman Ninja Nightwing, The Merciless, The Batman Who Laughs, Shazam/New 52, and Black Adam/New 52. Each character has a different passive ability, combat role, and team synergy. Before spending large amounts of resources, consider which character fits the teams and game modes you use most often.
One of the primary ways to obtain Metal characters is through Nth Metal packs. The Nth Metal Pro Pack costs 400 Nth Metal, while the Nth Metal Ultimate Pack costs 800 Nth Metal. The available Metal character pool and displayed drop rates can change, so players should always check the current in-game information before spending their resources.
Players often compare the 400 Nth Metal Pro Pack with the 800 Nth Metal Ultimate Pack before spending their resources. Commonly referenced odds put the Metal-character chance around 42% for the Pro Pack and around 60% for the Ultimate Pack, although players should verify the current displayed odds because pack contents and rates can change. The Pro Pack requires less Nth Metal per opening, while the Ultimate Pack provides a higher stated Metal chance per purchase.
Nth Metal is the key resource used for many Metal-related packs. Phantom Zone, Survivor Mode, Online Battle rewards, and other applicable game rewards can provide Nth Metal depending on the current content available to your account. Building a consistent routine around these activities is one of the best ways to gradually increase your Nth Metal supply.
Phantom Zone is particularly important because it can provide both Nth Metal and Valorium Alloy. Completing its objectives and opening crystals gives players access to rewards that can help with Metal character progression. When Phantom Zone is active, completing suitable objectives for your roster can significantly improve your resource progression.
Survivor Mode provides another opportunity to collect Nth Metal through its reward system. Online Battle rewards and other events can also contribute resources depending on the current game content. Combining multiple sources is more reliable than depending on a single activity.
Upgrading a Metal character involves more than collecting Nth Metal. Character promotions, Dark Power specials, Power Credits, Valorium Alloy, and gear all contribute to the character's overall progression. Your priority should be to invest resources into Metal characters that have strong synergy with your main teams.
Metal character promotions require additional copies of the same character. The commonly referenced progression is Elite I with 1 extra copy, Elite II with 1 extra copy, Elite III with 2 extra copies, Elite IV with 3 extra copies, Elite V with 3 extra copies, Elite VI with 4 extra copies, and Elite VII with 4 extra copies. Elite III is an important milestone because it unlocks additional Dark Power progression for Metal characters. Players should verify the promotion requirement shown on the current in-game promotion screen before planning their duplicate cards.

Metal characters have a unique Dark Power progression system connected to their special abilities. Reaching Elite III is an important progression milestone because additional Dark Power features become available. Valorium Alloy and Power Credits are important resources for developing these special abilities.
Valorium Alloy is a specialized resource associated with upgrading Metal character specials. Phantom Zone is the key source of Valorium Alloy, making the event especially important for players who want to maximize their Metal characters. If you are actively building a Metal roster, prioritize Valorium Alloy for characters that are central to your main teams.
When you have limited Valorium Alloy, prioritize the Dark Power specials that provide the biggest benefit to your team's strategy. A damage-focused character may benefit from offensive special upgrades, while a character built around control, defense, or support may benefit from a different upgrade path.
Batman Ninja Catwoman is one of the most recognizable Metal characters. Her kit is especially notable for relentless unblockable bleed pressure and Power Steal mechanics, making her a strong choice for players who want sustained offensive pressure. When upgrading her, prioritize resources and gear that reinforce her damage output and ability to maintain pressure.
Batman Ninja Nightwing brings a different style to a Metal-focused roster. His kit is associated with Dark Power drain upon tag-in and a Ninja team shield, giving him useful defensive and team-support potential. Build his gear and upgrades around the role you want him to perform within your Ninja-focused team.
The Merciless is another powerful Metal character with a distinctive defensive and offensive kit. His notable mechanics include an unblockable Armor passive and shield generation. These mechanics can make him valuable in teams that need additional survivability while maintaining strong combat pressure.
The Batman Who Laughs has unique mechanics involving Robin minion assists and Tarot cards. These mechanics give him a playstyle that is different from straightforward damage-focused Metal characters. When upgrading him, consider gear and teammates that allow his unique passive mechanics to remain active and useful throughout a fight.
Shazam/New 52 is notable for his KO prevention and his ability to provide 21-second damage immunity for Justice League and New 52 teammates through his unique mechanics. This makes him particularly interesting for players building teams around Justice League or New 52 synergies. Prioritize upgrades that complement his role as a defensive and team-support character.
Black Adam/New 52 can also be a valuable addition to a Metal-focused roster. His overall effectiveness depends on his passive abilities, special attacks, promotion level, gear, and team composition. Compare his strengths with your existing roster before deciding how heavily to invest your resources.
Gear is another major part of Metal character progression. Choose equipment based on the character's passive ability, basic attacks, special attacks, and role. Offensive characters can benefit from damage-oriented effects, while defensive or utility characters may benefit more from survivability, power generation, or complementary effects.
A strong Metal team should combine complementary roles rather than simply using the three rarest characters you own. Consider pairing a high-damage fighter with characters that provide useful defensive, control, support, or passive effects. Gear should also be selected to reinforce the team's overall strategy.
Maintain a reliable Gold roster so you can efficiently complete farming activities and participate in events that provide Nth Metal and other resources.
Participate in Phantom Zone, Survivor Mode, Online Battles, and other applicable activities to gradually build your Nth Metal supply.
Focus on Metal characters that fit your preferred teams and provide useful passive abilities or combat roles.

Invest duplicate character cards, Power Credits, and Valorium Alloy into the Metal characters that form the core of your strongest teams.

Be careful with websites claiming to generate unlimited Nth Metal, free Metal characters, or instant upgrades. Sites that request suspicious downloads, surveys, passwords, or unnecessary personal information can create security and account risks. A website's claim that a generator is safe does not guarantee that it is legitimate.
Some players consider third-party Injustice Mobile services when they want to reduce the amount of time required to build their roster. These services are separate from official game features and can carry account or service-related risks. If you consider using one, review the provider's current terms, requirements, and service details carefully before making a decision.
Unlocking and upgrading Metal characters in Injustice Mobile is a long-term progression process. Start by collecting Nth Metal through available activities, choose packs carefully, and prioritize Metal characters that fit your roster. Once you unlock a Metal character, focus on promotions, Dark Power specials, Valorium Alloy, Power Credits, and gear rather than trying to upgrade everything at once. Characters such as Batman Ninja Catwoman, Batman Ninja Nightwing, The Merciless, The Batman Who Laughs, Shazam/New 52, and Black Adam/New 52 can all become valuable parts of a developed roster when their abilities and team synergies are used effectively.
Metal characters can primarily be obtained through Nth Metal packs. The available characters and displayed odds depend on the current pack, so check the in-game pack information before spending Nth Metal.
The Nth Metal Pro Pack costs 400 Nth Metal, while the Nth Metal Ultimate Pack costs 800 Nth Metal. Pack contents and displayed odds can change, so players should verify the current information in-game.
Metal characters can be upgraded through character promotions, Dark Power special progression, Power Credits, Valorium Alloy, and gear. Phantom Zone is especially important because it provides opportunities to collect Valorium Alloy.
