Iso-8

The best Iso-8 class for Thunderstrike is Raider, since all of his attacks target multiple enemies, and he also has the ability to passively attack opponents. As a Raider, Thunderstrike can maximize his overall damage output thanks to the extra critical chance and critical damage that Raider provides. This makes him much more effective in battles.

Other Iso classes aren’t as good a fit for Thunderstrike. Fortifier could be a secondary option, as Thunderstirke passively applies Barrier to himself, Blastaar, and Asgardian allies on his turn. With Fortifier, these Barrier effects become even stronger, helping with survivability. However, Raider remains the optimal choice for maximizing Thunderstrike’s offensive potential.

T4 Priority

P – Passive ability

U – Ultimate ability

S – Special ability

B – Basic ability

Passive – Doubles the damage he deals when retaliating against enemies who attack him or any ally, increasing it from 150% to 300%, which is a good upgrade.

Awakened Passive – Gains even more control in Crucible Offense:

• If Blastaar is an ally, until Thunderstrike takes his first turn, enemies cannot fill their Speed Bar for themselves, their allies, or even their enemies (except through normal means), greatly slowing enemy teams.
• Also, if Blastaar is present, enemies cannot increase their Speed or Resistance except by Positive Effects, limiting their options for gaining an advantage through passive buffs or non-standard sources.

Ultimate – Thunderstrike will deal increased Piercing damage and apply Blind to a random Support enemy, which is a much stronger form of crowd control. Additionally, he will always call a random Blastaar ally to assist—an improvement from the previous 50% chance. These enhancements make his Ultimate more powerful and reliable, both in terms of damage and team synergy, giving you greater control over the battlefield.

Awakened Ultimate – Gains additional effects in Crucible Offense:

• Before the attack, it reduces the duration of all positive effects on all enemies by 2, stripping away their buffs.
• If the primary target is a Villain, Thunderstrike steals up to 2 Ability Energy from them, slowing their progress in using powerful abilities.
• If the primary target is a Hero, he instead applies Ability Block, preventing them from using their abilities.

Special – Deals more damage to both primary and secondary targets and applies Blind to the primary target. In Crucible Offense, he also applies Blind to adjacent targets. This upgrade is excellent because it significantly increases your control over the battle, making it much harder for enemies to land their attacks.

Basic – He will deal slightly more damage with it and apply Bleed to the primary and adjacent targets. This upgrade isn’t particularly significant on its own, but it is necessary if you want to unlock the Awakened Basic later. While the immediate benefits are minor, investing in this upgrade is a crucial step for those seeking to maximize Thunderstrike’s full potential in the future.

Awakened Basic – On Crucible Offense, reduce the duration of Regeneration on the primary and adjacent targets by 2. Basic’s damage will also increase from 280% to 360%, and he will apply 2 Bleed effects instead of just 1. While this upgrade is not game-changing, it can be useful in certain situations.

About Character

Thunderstrike is a superhero from the Marvel universe, best known as the alter ego of Eric Masterson. Eric was first introduced as a supporting character—an ordinary, hardworking architect and a devoted single father to his young son, Kevin. His life changed dramatically when he became entangled in the world of gods and superheroes after befriending Thor, the Norse God of Thunder.

Through a twist of fate, Eric was merged with Thor, sharing his body and mind with the god. This unusual bond gave Eric access to Thor’s powers and responsibilities. Eventually, when Thor was banished, Eric took up the mantle of Thor full-time, wielding the enchanted hammer Mjolnir and fighting alongside the Avengers. During this period, he struggled with the expectations and pressures of living up to the legendary hero’s reputation.

Realizing Eric’s courage and selflessness, the Asgardian god Odin later gifted him a unique weapon—a magical mace called Thunderstrike—after Thor returned to his original role. With this new identity, Eric became Thunderstrike. The mace, while similar to Mjolnir, was tailored to Eric’s character, symbolizing his own worthiness and heroism distinct from Thor.

As Thunderstrike, Eric faced supervillains, cosmic threats, and personal challenges, all while trying to maintain his relationship with his son and uphold his own ideals. His story is notable for its exploration of legacy, responsibility, and the struggle of an ordinary man thrust into extraordinary circumstances. Eric’s journey is marked by personal growth, moments of doubt, and acts of sacrifice, making him a unique and relatable hero within the Marvel Universe.

Thunderstrike’s legacy continues to inspire, showing that heroism isn’t just about power—it’s about heart, courage, and the willingness to stand up for what’s right, even when the odds are overwhelming.

Thunderstrike’s Legendary power truly shines on Cosmic Crucible Offense, delivering maximum impact in every fight. He plays a vital support role for his team by providing key utilities such as healing, health-steal, and Barrier application to certain allies, all managed through a Charged mechanic that he builds up with his Basic attack. This system allows Thunderstrike to strengthen his team’s survivability and keep them in the fight longer.

In addition to his support abilities, Thunderstrike controls the battlefield by Blinding enemies with two of his skills and applying Ability Block to Hero opponents, which can prevent them from using their most powerful Abilities. He also drains Ability Energy from Villain enemies, slowing down their attack cycles and giving his own team a strategic advantage.

Thunderstrike doesn’t try to overshadow Blastaar—instead, he complements him perfectly, acting both as a powerful support and a personal medic. He synergizes especially well with Blastaar, frequently calling him in for Assists on his Special and Ultimate Abilities. This interaction helps charge up Blastaar’s Bomb-Burst mechanic for faster, more devastating detonations. Furthermore, Thunderstrike redistributes stolen Health directly to Blastaar and provides him with extra Barriers through his Charged mechanic, making Blastaar even more resilient.

When used together with smart team building and strategy, Thunderstrike and Blastaar can anchor top-tier Crucible defenses, standing strong even against challenging opponents like Accursed and tricky Illuminati lineups. Their synergy and complementary abilities make them a formidable pair in the toughest battles.

Thunderstrike’s Basic ability is both powerful and versatile. When used, it attacks the primary target and adjacent enemies, dealing 280% damage and applying Bleed. This not only inflicts immediate damage but also causes additional damage over time thanks to the Bleed effect. Each use of this ability also grants Thunderstrike +1 Charged, which fuels his other abilities and makes him even more effective in battle.

With the Awakened version of his Basic, the attack becomes even stronger. Thunderstrike deals 360% damage to the primary and adjacent targets and applies 2 stacks of Bleed, significantly increasing the pressure on enemy teams. He still gains +1 Charged with each use.

Additionally, on Crucible Offense, Thunderstrike’s Basic has a unique benefit: it reduces the duration of Regeneration effects on the primary and adjacent targets by 2. This means he can counter healing-based teams and prevent enemies from recovering too quickly, giving his team a vital edge in Crucible matches

With Iso-8 / Counterattack / Assists, Thunderstrike performs the same action as his Basic attack, but only targets a single enemy. If Thunderstrike has his Awakened Basic, these Iso-8/Counterattack/Assist attacks also deal increased damage and apply 2 Bleed effects, just like the Awakened Basic. Additionally, on Crucible Offense, he will reduce the duration of Regeneration effects on the target by 2, providing extra utility against healing teams.

Thunderstrike’s Special is a versatile ability, costing 4 Ability Energy and being available on his very first turn. When activated, this ability attacks the primary and adjacent targets for 300% damage. It also applies Blind to the primary target, reducing their chances of landing successful attacks.

In addition to offense, Thunderstrike’s Special offers valuable team support. He clears 2 random negative effects from himself and all allies, helping the team stay free from harmful debuffs. He also heals himself and all allies for 20% of his Max Health, boosting the team’s survivability right from the start.

On Crucible Offense, Thunderstrike’s Special gains even more utility. It applies Blind not only to the primary target but also to adjacent enemies, greatly reducing the threat from multiple opponents. He steals 20% Health from the primary and adjacent targets, then redistributes 50% of the stolen Health to himself and a Blastaar ally, bypassing Heal Block effects. Finally, Thunderstrike calls a random Blastaar ally to assist, boosting the overall damage dealt in that turn and granting Blastaar additional Bomb Burst charges. It’s important to note that this is not a standard assist—enemies who have abilities that can block or prevent assists are not able to stop this effect. This unique mechanic ensures that Blastaar’s contribution is reliable and consistent, making the synergy between Thunderstrike and Blastaar especially valuable in battles where assist prevention is common. This feature gives your team a strategic edge, as you can count on Blastaar’s extra attacks and Bomb Burst progress regardless of enemy countermeasures.

Overall, Thunderstrike’s Special is a well-rounded ability that combines strong offense, team cleansing, healing, and strategic advantages in Crucible Offense, making him an essential asset in challenging battles.

Ultimate is a high-impact ability that costs 10 Ability Energy but can be used right on his first turn. When activated, it applies Blind to a random Support enemy. Thunderstrike then attacks all enemies with 400% Piercing damage—bypassing defenses—and applies Trauma, which prevents enemies from removing negative effects. He also steals 10% Health from all enemies and redistributes the stolen Health to himself and a Blastaar ally, completely ignoring Heal Block effects.

On Crucible Offense, Thunderstrike’s Ultimate provides even more benefits: he and a random Blastaar ally gain Safeguard, Defense Up, and Immunity, making them much harder to debuff or take down. He also calls a random Blastaar ally to assist, increasing the overall damage and Bomb Burst charge for Blastaar. Importantly, this attack is Unavoidable, so it can’t be dodged or missed.

If Thunderstrike’s Ultimate is upgraded to the Awakened version, it gains additional effects in Crucible Offense:

• Before the attack, it reduces the duration of all positive effects on all enemies by 2, stripping away their buffs.
• If the primary target is a Villain, Thunderstrike steals up to 2 Ability Energy from them, slowing their progress in using powerful abilities.
• If the primary target is a Hero, he instead applies Ability Block, preventing them from using their abilities.

Overall, Thunderstrike’s Ultimate is an ability packed with offensive power, team support, and strong control effects—especially in Crucible Offense. The Awakened upgrade makes it even more versatile, allowing Thunderstrike to disrupt both Villain and Hero enemies in different ways, and to strip away enemy buffs before hitting them hard. This ability can turn the tide of battle and is a key part of Thunderstrike’s kit.

Passive offers a powerful blend of healing, protection, and battlefield control.

On each of his turns, Thunderstrike heals himself for 20% of his Max Health. If he has the Charged, he provides an extra layer of protection by applying Barrier to himself, a Blastaar ally, and all Asgardian allies for 10% of his Max Health, then consumes 1 Charged. This helps keep key team members safe and sustained throughout the fight.

Whenever an enemy attacks Thunderstrike or any of his allies, he retaliates by attacking that enemy for 300% damage. On Crucible Offense, this counterattack also steals 10% of Thunderstrike’s Max Health from the attacker and redistributes 200% of the stolen Health to himself and a random Blastaar ally, bypassing Heal Block. This punishes enemy aggression and keeps Thunderstrike’s team healthy.

Additionally, on Crucible Offense and until Thunderstrike takes his first turn, enemies cannot gain Defense Up and allies cannot gain Offense Down, offering key early-game protection and momentum for your team.

If Thunderstrike’s Passive is Awakened, it gains even more control in Crucible Offense:

• If Blastaar is an ally, until Thunderstrike takes his first turn, enemies cannot fill their Speed Bar for themselves, their allies, or even their enemies (except through normal means), greatly slowing enemy teams.
• Also, if Blastaar is present, enemies cannot increase their Speed or Resistance except by Positive Effects, limiting their options for gaining an advantage through passive buffs or non-standard sources.

Overall, Thunderstrike’s Passive makes him a formidable protector and counterattacker, especially when paired with Blastaar and Asgardian allies. The Awakened upgrade adds powerful crowd control and speed manipulation, giving your team a significant edge in Crucible Offense and making Thunderstrike a cornerstone of defensive and control strategies.

This is the first time in MSF (Marvel Strike Force) that the developers have introduced a Legendary character whose main role is to support another Legendary character. Together with Blastaar, Thunderstrike becomes an extremely powerful duo in Crucible Offense. Their synergy allows them, especially when paired with the right additional characters, to overcome many of the strongest Crucible defensive teams.

However, outside of Crucible Offense and away from his partnership with Blastaar, Thunderstrike doesn’t offer anything particularly special. His full potential is clearly tied to this specific game mode and team composition. As a result, many players are now looking forward to the arrival of Annihilus to see how all three Legendary characters—Quasar, Blastaar, and Thunderstrike—will fit into the highly anticipated Annihilus mega META team. It will be interesting to see how these synergies develop and what new strategies emerge once the team is complete.
