Brilliant astrophysicist Dr. Siebren de Kuiper's life changed forever when an experiment gone wrong gave him the ability to control gravity; now, Talon manipulates him to their own ends.
De Kuiper was considered a pioneer in his field. His life's work involved devising a way to harness the power of gravity. Equally known for his groundbreaking research and eccentric personality, he conducted most of his studies from his lab in The Hague. Believing that he was close to achieving his goal, he performed his most important experiment on an international space station.
But something went wrong, triggering the brief formation of a black hole. De Kuiper was only exposed to its power for a moment, but he suffered serious psychological damage. The area around him began to experience strange fluctuations in gravity, peaking and dropping in time with his reactions. He had to be evacuated immediately.
Upon returning to Earth, De Kuiper was quarantined in a secret government facility. Between his ravings about the patterns of the universe, the psychic damage he sustained, and the gravitic anomalies happening around him, he was deemed unsafe and detained for years under the name "Subject Sigma." Isolated and unable to control his powers, De Kuiper retreated into his own mind. He thought he would never see the outside world again.
When Talon discovered De Kuiper's existence, they infiltrated the facility and broke him out, planning to use his brilliance and research to further their plans. In their custody, De Kuiper slowly gained control of his powers. Now, gravity moved according to his will, and he was closer than ever to achieving his life's goal. But the same experiment that had opened his mind had also fractured it, and he struggled to keep the pieces together.
De Kuiper continues to develop his powers in hopes of unlocking the secrets of the universe, unaware that Talon is using both him and his research.
- All seasonal event items, which are marked with special event icons ( • • • • • ), are only available to be unlocked either through their respective Loot Boxes or by Credits within the event's duration. During the event, newly-introduced event items cost three times as much as non-event items of the same rarity, while returning seasonal items are unlocked at the regular price.
At some point after his failed experiment, which led to his containment by the government, "Subject Sigma" was separated from the outside world for many years. Later on, however, Talon discovered him through unknown means and sought to retrieve him to further their agenda.
Sigma is an eccentric, ambitious and highly intelligent man, often revered as a pioneer in the field of astrophysics.
After suffering extreme mental damage due to an unknown error in his research and experiments, his mind was fractured beyond belief, causing him to become a raving lunatic and commenting on a "melody" seemingly only he could hear. For years after his confinement, he was isolated and had only his own psyche, likely altering it even further than it had initially been. Despite this, he remains dedicated to his work and hopes to finally harness the true power of gravity.
Outside of the madness, he thinks and speaks in a cold and somewhat curious tone, treating every event around him as an "experiment", even after respawning he will comment it wasn't "unwelcomed" and often using metaphores related to physics and astrophysics (such as Newton and stardust) but he will often yell in a maniacal way.
- The Hyperspheres only travel a maximum distance of 20 meters and automatically implode if they don't hit a target. However, they bounce off any inanimate object without exploding until the 20 meters are traveled.
- Because of how they bounce, you can do corner shots and make the most use of his attacks in enclosed spaces.
- To increase your accuracy, set your crosshair to default, but disable accuracy and set the line width to maximum. This almost exactly shows you where your Hyperspheres should land on a moving target.
- Kinetic Grasp
- His Kinetic Grasp works very similarly to D.Va's Defense Matrix, meaning it only protects what's in front of him. Sometimes damage taken from the side or back can be absorbed.
- This ability absorbs projectiles but not physical attacks or beams. Sigma can absorb every ability that Defense Matrix can.
- Kinetic Grasp is also similar to Zarya's Particle Barrier, where it buffs one aspect of the character (offense and defense respectively).
- While using Kinetic Grasp, you can effectively nullify damage towards your shield by standing directly behind it. You can also call back your barrier while using this ability.
- Experimental Barrier
- His barrier will not regenerate health while active, so whenever you don't need the shield anymore, call it back immediately. It is very easy to forget about the shield.
- His barrier can be placed further away from him. This gives him the ability to protect teammates from distance or block enemy fire from a distance.
- Experimental Barrier can be used to block long ranged heroes, such as Widowmaker, Hanzo, Ashe, or Ana. This works the least against Hanzo, because he is the most mobile sniper.
- If the Experimental Barrier is on low health under fire, try to recall it just before it breaks becuase doing so means it can regenarate straight away rather than having to wait 5 seonds until it start regenerating again.
- Use this ability sparingly, as the large cooldown will leave you without the chance to get quick picks later in the fight.
- Accretion can be used to save supports being punished by either flanking Damage heroes or bruiser type tanks (such as D.Va) by either stopping them from escaping or pursuing their target.
- Since it stuns, using this ability on a channeled Ultimate ability will stop that ultimate. These include Reaper, Pharah, Roadhog, and Sigma, among others.
- When comboed with Sigma's primary fire, you can one-shot combo any hero that has 200 or less total hitpoints, with Hyperspheres doing 110 damage, and Accretion dealing 90.
- Gravitic Flux
- Similar to Meteor Strike, the selected area will be revealed to the enemy. Therefore, you will want to the enemy team to be distracted while you are using this as they will disperse to avoid being caught in your Ultimate. Try combining your Ultimate with Earthshatter and/or Graviton Surge to ensure you have heroes in your Ultimate when cast.
- Once an area is selected, the ability will continue to suspend the enemies but not slam them down if Sigma dies, gets stunned, or gets hacked.
- If you find yourself on low health will using Gravitic Flux try to get behind cover because it can be better to make sure you complete the Ultimate rather than risk yourself dying.
- To get the most value of Gravitic Flux make sure you and your team are ready to follow up on the weak enemy's becuase if you don't the enemy supports will be able to heal up the whole to team, probably getting a lot of ultimate charge in the process.
- Communicate with your DPS teammates when you're casting Gravitic Flux, as they will be able to capitalize on it with either damage output or usage of an ultimate while the enemies are suspended in the air.
- With some practice, you can pair this ability with Minefield and Self-Destruct. Timing and communication will be key, as all three Ultimates have a warm-up before they are able to deal damage.
- Using this ability over the objective can cause Overtime to end during the suspension phase, so it is highly recommended to use this to your advantage if there is only a few heroes on point contesting to force them off or into the air.
- Gravitic Flux has a relatively high range, making it easy to grab a flying Mercy or Pharah while they are closer to the ground.
- Make sure Zarya has used her Particle Barrier and Projected Barrier before casting Gravitic Flux becuase both can completly nulify your ultimate on top netting the Zarya a lot of Energy.
- Sigma was revealed on July 22, 2019.
- Sigma is the oldest playable character in the game, being 62 years old.
- Sigma has 3 sprays referencing Dutch painters, Night Sky being a reference to Van Gogh's "Starry Night" painting and "Gravity" and "Apple" referencing M. C. Escher's paintings "Relativity" and "Bond of Union", respectively.
- The Apple spray also references the famous correlation between Newton and his representation with the apple as his experiment with gravity, further reference in his voiceline "Like Newton and the apple", often said when eliminating an enemy.
- The spray "Schrödinger's cat" showing a box with a cat's face painted on it references the experiment of Schrödinger's cat, where a cat in a box can not be seen as dead or alive until inspected, being theoretically both dead and alive, an easy explanation coined by Schrödinger to explain particles that exist in both states until inspected.
- His "Damage" spray portrays an EMR of his head, but the image inside references the first recorded image of a black hole.
- His "Galileo" spray references the experiment where a bowling ball and a bunch of plumes fell at the same speed in a vacuum.
- The name also references the scientist Galileo Galilei, who contributed to modern science with several studies regarding planetary orbit and gravity.
- Sigma's theme song bears similarities to Erik Satie's Gnossienne n°1, a piano song composed without a pattern of time.
- The skin "Asylum" has Sigma wearing a face mask of the same kind worn by Anthony Hopkins as Hannibal Lecter in the movie The Silence of the Lambs.
- His surname De Kuiper comes from the Dutch astronomer Gerard Kuiper, the eponymous namesake of the Kuiper Belt.
