Marvel Contest of Champions Reveals the Mighty Mister Sinister

Marvel Contest of Champions Mister Sinister

Mister Sinister is officially making his way into Marvel Contest of Champions, and it’s up to you whether you will serve willingly, or fight against the X-Men and the Brotherhood. He’s best known for his horrific work in gene manipulation, and his various schemes across the X-Men universe, such as the birth of Nathan Summers. Below are his bio, stat, and abilities.

“Nathaniel Essex, a scientist in the latter half of the 19th century, pledged loyalty to the mutant-demi god Apocalypse in exchange for activation of his dormant X-Factor. Donning the moniker of Mister Sinister, Essex began to engineer bloodlines in the hope of creating the perfect mutant. His attention would eventually focus on two particularly gifted children, Scott Summers and Jean Grey. In command of the Marauders, a band of mutants that follow him, Mister Sinister has been the mastermind of many schemes and plots, not the least of which was the birth of Cyclops and Madelyne Pryor’s child, Nathan Summers, also known as Cable.”

Developer Notes: Mister Sinister’s Immunity to mind manipulating effects will help him both when attacking and defending.

Molecular Regeneration – Passive

  • Mr. Sinister’s Regeneration Rate cannot be lowered below 0%.
  • 100% chance to Regenerate 70% of damage dealt by enemy Critical Hits over 0.4 seconds. Abilities cannot affect the Ability Accuracy, Duration, or Potency of this ability, aside from effects that would modify Mister Sinister’s Regeneration Rate.
  • Regeneration Rate is increased by 1% for every hit on the opponent’s Combo Meter up to 50 hits.

Developer Notes: Bringing a Heal Blocking champion will be essential when fighting Mister Sinister when placed on complimentary AW Nodes. Another important note is that Damaging Debuffs will not trigger Sinister’s Regeneration, but run the risk of being Transferred to you as a result of his first Special Attack.

While Heavy Attack Charging:

  • Pauses the duration of Damaging Debuffs, Stun, Concussion, and Power Leech on the opponent.
  • Charging a Heavy Attack for 1-second grants a Precision Buff, increasing Critical Rating by 857.14 for 6.2 seconds. This Precision provides 857.14 additional Critical Rating for each Debuff on the opponent.
  • Charging the Heavy Attack for an additional 1-second grants a Cruelty Buff, increasing Critical Damage Rating by 127.66 for 4.9 seconds. This Cruelty provides 127.66 additional Critical Damage Rating for each Debuff on the opponent.

Developer Notes: Utilizing Sinister’s Ability to Pause the Debuffs he inflicts or Transfers will allow you to get the most from their potent effects. When paired with a Stun, it’s possible to easily gain added Critical Rating and Damage by fully charging the Heavy Attack.

Special Attacks:

Special 1 – Genetic Disruption:

Mister Sinister sends a pulse of energy, infusing his opponent with faulty genetic material.

  • 100% chance to Transfer all Damaging Debuffs to the opponent for 4 seconds. This ability activates even if this attack is Blocked or avoided.
  • 100% Chance to cause Degeneration, inflicting 990.4 Direct Damage over 4 seconds.

Developer Notes: It’s important to remember that the Transfer of Damaging Debuffs cannot be prevented. Definitely reconsider bringing any epic Bleed champions in against him.

Special 2 – Genetic Negation:

Disabling several important genes can render the opponent powerless, in this case, it also leaves the opponent in a catatonic state.

  • 100% chance to inflict Concussion, reducing the opponent’s Ability Accuracy by 100% for 6 seconds. This ability activates even if this attack is Blocked or avoided.
  • 100% chance to Stun for 2.5 seconds.

Developer Notes: Facing off against a prolific Evader? How about an enemy who likes to trigger a defensive ability when struck? Worry not, Sinister’s Special Attack will ensure those abilities don’t get in the way of this Special Attack.

Special 3 – Genetic Extraction:

Once an exciting genetic structure is discovered, Mister Sinister takes great pleasure negating its beneficial effects and extracting its essence for himself.

  • 100% chance to inflict Concussion, reducing the opponent’s Ability Accuracy by 100% for 12 seconds.
  • 100% chance of applying Power Leech to the target, stealing 20% of Max Power over 3 seconds.

Developer Notes: The culmination of Sinister’s work, make sure to Pause the Power Leech to maximize the Power he is able to steal once the attack ends.

Signature Ability – Engineered Perfection:

Mister Sinister is able to improve himself with the genes of defeated opponents.

  • Each time Mister Sinister defeats an opponent, he extracts their genetic code, gaining a different Passive ability for the rest of the quest depending on the defeated Champion’s Class. [Max 3 of each Passive, 10 Passives total.]
  • Mutant: Prowess, increasing Special Attack Damage by 30%.
  • Skill: Precision, increasing Critical Rating by 500.
  • Science: Regen Rate, increasing Regeneration Rate by 20%.
  • Mystic: Power Rate, increasing Power Rate by 20%.
  • Cosmic: Fury, increasing Attack Rating by 371.4.

Developer Notes: Sinister is always in pursuit of perfection, be sure to use him often to build his strength over the course of a quest. Inversely, for those fighting him, it’s also important to note that losing a Tech champion to Sinister will not grant him any Passive effects.
