Basic – Disintegration Beam, Marvel Strike Force Ultron’s basic attack deals 340% damage to the primary target, steals two positive effects, and may clear Taunt, making it useful for offense and buff removal. The Taunt removal depends on Focus vs. Resistance.

Special – Factory Upgrade, this ability starts fully charged and summons up to three bots with 340% of Ultron’s damage and 100% of his health at max level. It gives Defense Up to Ultron and bots for two turns. Bots offer team buffs like Offense Up or Speed Up. In Cosmic Crucible, they gain Deathproof and 10% Speed Bar. Ultron and the bots then attack the target together, making it a strong move especially in Crucible.

Ultimate – Purge System, available on turn two, this attack deals 700% Piercing damage, doubled if the enemy has Defense Up. Ultron gains ability energy based on his positive effects, often refreshing cooldowns. At level 7, damage increases by 80%. In Cosmic Crucible, with three Masters of Evil allies, it also removes all Deathproofs from the target before dealing damage.

Passive – Ultron Prime, Marvel Strike Force Ultron revives once at 50% health if he starts the match at full health. On killing an enemy, he and Villain allies extend positive effects; level 5 is required to extend all buffs. In Cosmic Crucible, he gains 15% Speed Bar on spawn and grants 50% extra Armor to himself and Masters of Evil allies.

Team Synergies

Ultron’s strengths lie in his Villain and Tech classifications, as well as his role within the Masters of Evil team. His passive allows him to prolong all positive effects on Villain allies whenever he scores a kill, making him an asset to any Villain-heavy lineup that benefits from extended buffs. This effect becomes fully active at level five, enhancing his support potential.

Ultron fits naturally into Tech-based teams. While he doesn’t directly boost other Tech allies outside of his minions, shared tags can help him slot into compositions that rely on Tech synergy and strategy. Teams that benefit from shared traits, like turn meter gains or supportive Tech abilities, can enhance Ultron’s effectiveness through indirect synergy.

His most prominent role is with the Masters of Evil, where he gains significant advantages in Cosmic Crucible. In this mode, Ultron starts with a bonus to his Speed Bar and grants an additional 50% Armor to himself and all Masters of Evil allies. This team—typically including Kang, Moonstone, Titania, and Absorbing Man—is highly effective in Crucible offense, with Ultron playing a central part in their durability and damage output. Even a partial Masters of Evil lineup with Ultron and Kang, supplemented with other Villain Tech characters, can perform well in this mode.

Ultron has also been utilized in hybrid teams across various game modes. The AIMTron setup pairs him with Scientist Supreme, Graviton, AIM Assaulter, and AIM Security for War offense, using Scientist Supreme’s buffs to strengthen Ultron’s presence. He has also substituted into Power Armor teams in place of Iron Man, formerly offering strong counters to teams like the Emmarauders. Additional creative setups have included Ultron alongside X-Men characters in War, or with Ghost, Yellow Jacket, and Minn-erva in Villain Tech compositions.

His minions are central to his performance. Each minion contributes buffs such as Offense Up, Speed Up, or Regeneration to Ultron and other minions. In Cosmic Crucible, they gain Deathproof and additional Speed Bar, and when Ultron uses his special, they all assist in the attack, increasing the damage burst and buff spread.

Ultron also pairs well with specific characters like Minn-erva, who can heal and revive; Ghost and Yellow Jacket, who share the Tech tag and synergize well in turn-based play; Shuri, who provides healing and Defense Up; and Hela, who has been part of successful Arena teams alongside Ultron, Thor, and others.

Ultron in Different Game Modes

In Arena, Ultron has a mixed Arena presence in Marvel Strike Force due to being easily targeted and countered by characters like Black Bolt. While not meta-defining, he can still fit into creative hybrid teams for utility and buff extension. Alliance War, Ultron excels in War offense, especially in hybrid lineups like X-Men-tron or PowerArmor-tron. His ability to summon bots and extend buffs helps these teams punch up effectively.

Raids, a staple in early Tech raid teams, Ultron pairs well with sustain-heavy allies like Shuri and Minn-erva. His bots add survivability, though gear investment is crucial for raid viability. Dark Dimension, unlocked by completing Dark Dimension II, Ultron is a major power spike for new players. While less central in later Dark Dimensions, his early impact and team flexibility remain valuable.

Blitz & Real-Time Arena, Ultron is strong in Blitz, carrying weak teams for efficient rotations. In RTA, his slower speed and vulnerability limit him, but he performs well with the right support. Cosmic Crucible, Ultron shines in Crucible with the Masters of Evil, offering bonus Speed Bar, Armor, and upgraded bots. His synergy and high-impact attacks make him key to one of the top offensive teams.

ISO-8 Recommendations

The most commonly used ISO-8 class for Marvel Strike Force Ultron is Striker, which enhances his role as a Blaster by boosting his damage and enabling follow-up attacks when Vulnerability is applied. This is especially effective when paired with allies who can consistently apply Vulnerability, helping Ultron secure kills—critical for triggering his passive, which extends positive effects on Villain allies and improves energy flow.

Other ISO-8 classes offer situational value. Fortifier adds survivability with barriers, useful if Ultron has low health or needs to stay alive long enough to use his stronger abilities. Healer provides team-wide Regeneration for sustained fights, though it's less common. Despite these options, Striker remains the best fit overall due to its direct synergy with Ultron’s high-damage, kill-focused kit.

Red Stars for Ultron

Red Stars for Ultron are not awarded through additional completions of Dark Dimension II (DD2). While completing DD2 for the first time unlocks Ultron at 5 stars and a second run upgrades him to 7 stars, Red Stars are handled separately. Once you’ve unlocked Ultron, you gain access to purchase his Red Stars using Dark Promotion Credits in the Elite Store. These credits are a premium currency, earned in small amounts, and are required for promoting special characters like Ultron who are not available through standard Red Star Orbs.

At one point, the option to purchase Red Stars for Ultron using Dark Promotion Credits was temporarily disabled, coinciding with an event designed to let players earn his Red Stars through gameplay. This event was expected to align with the release of Ultron’s rework and his synergy with the Masters of Evil team. During such events, Red Stars for Ultron may be offered as milestone or event rewards.

Currently, the most reliable way to obtain Red Stars for Ultron is through the Elite Store, spending Dark Promotion Credits when available. These purchases enhance Ultron’s stats in line with standard Red Star promotions, but do not affect his star level. Players looking to power up Ultron should plan their Dark Promotion Credit spending carefully, especially when considering other limited-availability characters.

T4 Ability Upgrade Priorities

Recommended T4 order: Special > Passive > Ultimate > Basic.

Basic - When investing T4 ability materials into Marvel Strike Force Ultron, the recommended priority is: Special, Passive, Ultimate, then Basic, based on overall value and synergy—especially in Cosmic Crucible and with the Masters of Evil team. The Special is top priority, guaranteeing Ultron summons three minions who provide buffs like Offense Up and Speed Up. In Crucible, they gain Deathproof, bonus Speed Bar, and assist his attack, giving this upgrade strong offensive and defensive impact.

The Passive is next, upgrading the effect extension on kill from four to all positive buffs. In Crucible, it also grants +15% Speed Bar and +50% Armor to Ultron and Masters of Evil, greatly boosting team survivability and early tempo. The Ultimate is a strong damage upgrade, dealing high Piercing damage that doubles if the target has Defense Up. With T4, it also removes all Deathproofs in Crucible when used with at least three Masters of Evil allies.

Conclusion

Ultron is a valuable character in Marvel Strike Force, unlocked by completing Dark Dimension II, which grants a 5-star Ultron on first completion and 7-star on the second. As a Villain, Global, Tech, Blaster, he offers strong damage, summons minions that provide team buffs, and prolongs positive effects for Villain allies on kill. Though durable with high health and armor, his average speed and focus can limit his debuff potential.

Ultron performs well across multiple modes. In Cosmic Crucible, he excels with the Masters of Evil, gaining Speed Bar, Armor boosts, and enhanced bots. In Alliance War, he fits into versatile “tron” hybrid teams like PowerArmor-tron or X-Men-tron. While less dominant in Raids today, he was once a tech-lane staple and can still contribute in the right setup. He also has situational value in Arena with creative hybrid teams.

Despite shifting metas, Ultron remains a strong long-term investment. His synergy with Villain Tech teams, reliable utility, and continued effectiveness in Crucible and War make him a top pick for both new and experienced players.
