Iso-8
For Thanos, we have multiple options. He can be a Raider to boost his Ultimate, and that is perhaps the best class for him in War, since he plays first and will not have Vulnerable on enemies available to exploit. Striker is also a solid option when using the Shadow Conclave team outside of War, as he will then apply additional Counters to himself through his Iso-8 attack. Besides these two more offensive options, Thanos can also be a Fortifier. Through that class, we boost his mitigation, and since he is a Protector who draws enemy attacks onto himself through Taunt, Fortifier is a very reliable choice.
T4 Priority
P – Passive ability
S – Special ability
B – Basic ability
U – Ultimate ability
Passive – Thanos will, on enemy Death, always generate 1 Ability Energy for himself and 1 Ability Energy for 2 random adjacent Cosmic allies, upgraded from a 75% chance to do so on enemy Death. So whenever one of the enemy characters dies, Thanos will always provide Ability Energy to himself and his adjacent Cosmic allies — all Shadow Conclave characters are Cosmic, so they all fall into that category. This upgrade is essential for Thanos not only as a Shadow Conclave team member, but also if we want to use him in Dark Dimension.
Special – With a maxed Special, Thanos will deal greater damage, and in War, with 3 Shadow Conclave allies, before this attack, he will clear all negative effects from himself and all Shadow Conclave allies, upgraded from clearing 2 negative effects. So with this upgrade, the Shadow Conclave team will be cleansed of negative effects at the very start of the fight in War, if any enemies have applied negative effects to them on Spawn, since Thanos will always play first in War regardless of anything.
Basic – Deals slightly greater damage, but the more important aspect of the upgrade is that it applies 2 Counter to himself and in War with 3 Shadow Conclave allies, 2 Counter to a random Shadow Conclave ally without Counter. Upgraded from 1 Counter for himself and a random ally without Counter. A solid upgrade that allows us to counter enemy attacks more frequently.

About Character
Born on Saturn’s moon Titan as the son of Eternals A’lars and Sui-San, Thanos carries the Deviant gene, giving him the physical appearance of the Eternals’ cousin race. His mother, Sui-San, was so shocked by his appearance — and her belief that he would destroy all life in the universe — that she went insane and attempted to kill him at birth, though A’lars stopped her. During his school years, Thanos was a pacifist who played only with his brother Eros and his pets. By adolescence, however, he had become fascinated with nihilism and death, eventually falling in love with Mistress Death herself. As an adult, he augmented his physical strength and powers through science, attempted to sire children, and became a pirate — but found no fulfillment in either until Mistress Death visited him again, for whom he murdered his own offspring and his pirate captain.
Thanos’s romantic pursuit of Death became the engine of his cosmic ambition — many of his earliest actions stemmed from his wish to impress her in hopes she would return his affections. Having collected all six Infinity Gems — governing Time, Space, Mind, Soul, Power, and Reality — and mounted them on his gauntlet, Thanos gained power over essentially everything. He used that power to eliminate half of the universe’s sentient beings, fulfilling what he believed was Death’s desire for balance. Ironically, Death rejected the gesture — claiming he was now her superior. Thanos had gained her submission, but not her love.
Afterwards, Thanos spent time as a lowly farmer reflecting on his past misdeeds. Adam Warlock disassembled the Gauntlet and entrusted Thanos with the Reality Gem, making him a member of the Infinity Watch. As part of the group, Thanos redeemed himself by protecting the Gems against Magus, an evil version of Adam Warlock. When Death offered her allegiance if he would kill Warlock, Thanos surprisingly declined and fought against Magus instead. The Mad Titan’s arc is one of Marvel’s most enduring contradictions: a being of immeasurable power and bottomless hunger, undone again and again not by his enemies, but by his own subconscious desire to fail.
Thanos is the Protector of the Shadow Conclave — and he plays the role from the very first second of every battle. In Alliance War, he fills his own Speed Bar by 50% at the start of every fight, guaranteeing he plays first, taunts early, and immediately begins protecting his team. His ability to fill Speed Bars for himself and his allies cannot be prevented in War, so no enemy mechanic can stop this from happening.
Once he has Taunt, the whole Shadow Conclave team benefits from a staggering +2,500% bonus Resistance, provided Thanos doesn’t have 2 or more Exhausted. That number makes it nearly impossible for opponents to land debuffs on this team while Thanos is standing and taunting, fundamentally changing how the matchup plays out.
Beyond protection, Thanos functions as an Ability Energy battery for his allies. On enemy deaths, he generates 1 Ability Energy for himself and 1 Ability Energy for 2 random adjacent Cosmic allies. Since every Shadow Conclave member is Cosmic, this will always fire within the team, keeping the squad fueled throughout the fight. He also has a dedicated synergy with Executioner — whenever a non-summoned enemy drops below 25% Health, Thanos generates 1 Special Ability Energy for his Executioner ally and fills Executioner’s Speed Bar by 25%, accelerating the team’s most aggressive damage dealer at exactly the right moment.
His Special and Ultimate both grant him Taunt, meaning he can re-establish protection multiple times throughout the fight. His Ultimate attacks all enemies and comes with +100% Drain, so every point of damage he deals heals him back — a self-sustaining burst that keeps him in the fight longer. In War, he can clear negative effects from himself and all Shadow Conclave allies, and he is also capable of stripping Revive Once and Charged from one of his enemies, neutralizing some of the most powerful defensive mechanics in the game.
Finally, his Basic grants him 2 Counter, turning the Protector into a genuine threat on the counterattack. In War, he also applies 2 Counter to one random Shadow Conclave ally, spreading that defensive pressure across the team.
