ULTRON has been updated in Marvel Contest of Champions! Learn more about his updates here:


“What is this? What is this place? This…Contest? I wasn’t always here, in this place. I was asleep…or perhaps I was a dream. But now I’m here and on mission. I am Ultron, created by Stark to bring about peace in our time. But humanity cannot be saved in its current state. No, we need a new world to supplant humanity. A world of metal. I’ll create peace in the only way it can be achieved. Not in Stark’s way, but in my own. How is humanity saved if it’s not allowed to evolve?”

ULTRON’s Mechanics

Manage your Functions, and activate as many as possible! Combine your Heavy Attack and Specials to gain a bunch of bonus Attack and land some massive Bleeds and Critical hits with Ultron’s updated kit!


  • Immunities
    • Ultron being a Robot gains full Immunity to all Bleed and Poison effects.
  • Damage over Time
    • Ultron can apply some massive Bleed damage, and against mutants even Degeneration!


  • Anti-Evade
    • To maximize Ultron’s power you’ll want to activate all of his Functions, including the Evade. Watch out for anyone that can shut it down!

The following Stats and Abilities are based on a Rank 5, Level 65, 5-Star Champion


Always Active

  • Advanced robotics causes Ultron’s Function abilities to have a 100% chance to trigger and to be unaffected by Ability Accuracy. Additionally, Ultron is Immune to Bleed, Poison and Slow effects.
  • Function (Evade) – Every 7 seconds, Evade all incoming Attacks for 1.5 seconds.

Dev Notes: Ultron’s Evade now has an icon to display it, making it easier to track when it will trigger, but we’ve also increased the duration!

When Health Drops Below 50% and 25%

  • Function (Heal) – Once Per Fight – Gain a Self-Repair Buff healing 8306.75 Health over 10 seconds. If Stunned while Self Repair is active, Connection is Lost and the Self-Repair is removed.

All Attacks

  • Function (Critical) – Every 5th Attack is a guaranteed Critical Hit.
  • Function (Damage) – Every 3rd Attack inflicts a Bleed Debuff, causing 1394.4 direct damage over 6 seconds. If the target is Mutant, instead inflict a matching Degeneration Debuff.

Dev Notes: Those pesky Mutant Champions won’t be able to slip away from Ultron’s Damage Over Time.


  • Function (Armor) – Every 4th Blocked Attack grants an Armor Up Buff, providing +370.59 Armor Rating for 30 seconds. Well-Timed Blocks count as 4 Blocked Attacks for this purpose.

Heavy Attack

  • Triggers Function (Damage) for each unique Function Ultron has utilized during the fight. Cooldown: 5 seconds per unique Function utilized during the fight.

Launch a Special Attack

  • Function (Cauterize) – Remove all effects from the opponent caused by Ultron’s Function (Damage). Gain +1162 Attack Rating for each effect removed this way for the duration of the Special Attack.

Dev Notes: Pair this with a well timed Special 2 and Heavy Attack to get a massive amount of Bleed damage or Fury!

Special 1 – Encephalo-Ray

  • Function (Stun) – Inflict a Stun Debuff lasting 2 seconds.

Special 2 – Attack Routine 11010100

  • The Attack bonus granted by Function (Cauterize) lingers for 10 seconds after this Attack is finished.
  • Any Function (Damage) Debuffs triggered during this Attack are doubled.

Dev Notes: Make sure to time this well with when your next Function:Damage will trigger for maximum damage!

Special 3 – Eradication

  • Function (Stun) – Inflict a Stun Debuff lasting 3.5 seconds.
  • Function (Burn) – Inflicts Power Burn, draining 2 bar(s) of Power and dealing direct damage proportional to the Power Drained.

Signature Ability – Absorption

Energy Damage Effects

  • Attacks that deal Energy Damage cause Ultron to Regenerate 65.96% of the damage dealt to him. Each Energy-based Attack also grants Ultron a burst of Power based on the damage dealt.

  • Double Edge and Liquid Courage
    • Ultron being immune to both Bleed and Poison makes him a great candidate for both Double Edge and Liquid Courage.
  • Deep Wounds:
    • Ultron has fairly short Bleed Debuffs, juice out as much damage as you can with the Deep Wounds mastery!
