Our world is worth fighting for.

Mei is one of the heroes in Overwatch. She is a climatologist who is on her own adventure to preserve the environment and ecosystem after waking up from a decade-long cryostasis sleep.

Mei’s weather-altering devices slow opponents and protect locations. Her Endothermic Blaster unleashes damaging icicles and frost streams, and she can Cryo-Freeze herself to guard against counterattacks or obstruct the opposing team's movements with an Ice Wall.



Mei is a scientist who has taken the fight to preserve the environment into her own hands.

Though many blamed the planet's escalating, unexplained climate phenomena on the advent of new technologies, the rapidly growing omnic population, and drastically increased consumption of resources, the true cause remained unknown. To find a solution, Overwatch established a series of eco-Watchpoints at remote, critical locations worldwide.

Mei-Ling Zhou was a member of this multiyear initiative. A peerless climatologist, she had introduced cutting-edge innovations in the field of climate manipulation that protected at-risk areas in Asia and beyond. She was assigned to the program's monitoring station at Watchpoint: Antarctica when disaster struck: a sudden, catastrophic polar storm battered the installation and cut it off from the outside world, leaving the facility damaged and the scientists stranded. As their supplies dwindled, they entered cryostasis in a last-ditch effort to survive until a rescue attempt could be made.

But that rescue never came. It was years later when the team's cryogenics chamber was finally discovered. Mei, still in hibernation, was the only survivor. The world Mei awoke to had gone through considerable changes: Overwatch was no more, the serious climate issues had worsened, and none of the eco-Watchpoints were in operation. Any clues that they had uncovered were lost.

Mei has decided to continue her work on her own. Equipped with a portable version of her climate-manipulation technology, she travels around the world, hoping to re-establish the eco-network and track down the causes of the threats to the planet's ecosystem.

Mei in Rise and Shine.

Mei-Ling Zhou was an innovative member of Overwatch's ecological studies whose technology was used around Asia for climate preservation. She was assigned to work with other scientists at Ecopoint: Antarctica when a polar storm cut off their communications and left them stranded. They entered cryostasis to survive until a rescue mission was made.

After approximately nine years had passed, Mei awoke from her cryostasis. Subsequently awakening Snowball, her assistant drone, from its inactivity and preparing for the day, Mei checked on the atmospheric fluctuations above the anomaly only to find out that they had been much worse than her team had predicted. Anxious about the sudden appearing data, she asked Snowball about long they had been dormant only to discover terrible news thereafter: Not only had Overwatch shut down, but all of her team had expired during their nine-year stasis, leaving Mei as the only survivor. As Mei cried for hours over the death of her friends, she came to the slow realization that their newfound data could save millions of lives, and promised that she will show her work to the world by any means necessary.

Following many failed attempts to leave the ecopoint, Mei became aware that their base had been broadcasting on the Overwatch emergency frequency and began the process of building the Endothermic Blaster, which could aid her in getting up to the radio tower. Unfortunately, when her creation was almost finished, the power had gone out, leaving the last battery dead. The power eventually came back on, but it came at the cost of Snowball's battery life, leaving Mei in a saddened state once again. When the blaster was completed, Mei returned outside and used its ice to her advantage on her dangerous climb to the top of the tower. Once she reached the summit, she gained a signal and received an announcement from Winston on recreating Overwatch. Eager to get the organization back together, Mei set out to rejoin civilization, but not before recharging Snowball with a solar-powered device and leaving warm cups of cocoa on the cryostasis pods.

Mei appeared to have met Winston before her decade-long trip to Ecopoint: Antarctica. Winston also recommended that Mei keep a journal of her travels. After the rescue, Mei had traveled to remote regions around the world, investigating Overwatch's abandoned Eco-watchpoints.[2] On her trip, she went to Mount Logan, Canada to test her technology, took a quick stop in Los Angeles on Halloween, then went to Nepal for an unknown project.[3] At some point, Mei saved a nest of endangered arctic wildlife from a collapsing glacier.[4]

Mei appeared on live TV in Christmas, reporting a snowstorm striking the United Kingdom.[5]

At some unknown point Mei joined both Winston and Tracer in the newly reformed Overwatch's first public mission in Paris, France to deal with Null Sector who was invading the city, She expressed concern however about their chances, do to the fact she and Lena were the only agents so far to answer the recall leaving them with a three-person strike-team. After joining the battle the team was doing well until they encountered a giant omnic who destroyed their dropship and ruptured a gas line causing an explosion. While Mei was able to put up an ice wall to protect two French police officers and a little girl from the explosion, the shock wave flung here backward into a car injuring her shoulder.

With the odds against them, Winston ordered Tracer to take Mei to safety while he held off Null Sector. Despite Mei's protests that they were supposed stick together, the scientist promised to join them soon. Luckily, Winston was saved by the timely intervention of Genji before Reinhardt, Brigitte, Echo and Mercy, who provided healing for Mei, joined the fight. Mei soon combined her backpack with Tracer's pulse bomb as an improvised cryo bomb that snap froze and destroyed the giant omnic. In the aftermath, Tracer introduced Mei to her colleagues; Reinhardt made an ice pun while shaking hands with her, to Brigitte's annoyance.


Mei is very kind-hearted and positive, showing compassion for others and having a desire to preserve Earth's ecosystem for generations to come. As a scientist, she is willing to learn new things and is even inspired by Tracer as well as Winston. She also hates bullies, as shown by one of her quotes and an interaction with Junkrat.

At times, Mei appears to be slightly bashful. She is also very apologetic, often saying "Sorry!" when defeating enemies.

Mei is also shown not to have a fear of heights, as seen in Rise and Shine while she was climbing the tower with her endothermic blaster.



For more detailed tips as well as hero matchups, see Mei/Strategy.
  • Mei slows and freezes enemies, making them vulnerable to attack.
  • Mei's ice theme is purely cosmetic: she does not give or receive greater damage from fire-related weapons.
  • The end of Mei's Cryo-Freeze is signaled by the sound of cracking ice. However, there is no special sound other than a brief crack if Mei ends the Cryo-Freeze early. Use this to Mei's advantage, as enemies may be caught off guard.
  • Mei in Cryo-Freeze can negate certain abilities such as McCree's Deadeye and D.Va's Self-Destruct, making it good as an impromptu shield for allies. However, it cannot negate abilities like Hanzo’s Dragonstrike or Reinhardt‘s Earthshatter, only blocking the damage for herself.
  • Mei can still be healed by outside sources such as Mercy's healing during its duration.
Ice Wall
  • Try placing the wall at a precise position so as to effectively block abilities that deal high amounts of damage.
  • Ice wall has many uses beyond stopping attacks and movement:[6]
    • Placing it in front of Torbjörn's Turret effectively disables it (as it obstructs its laser guidance) for as long as the ice wall stays up.
    • The ice wall can also be used for Mei and her team's movement, as it can be placed under her or others to get them to higher places they normally couldn't get to.
    • Players can toggle between perpendicular and parallel placement of ice wall by pressing the ice wall button again. Alternatively, if they place a wall unintentionally, they can click the ice wall button again (while it is up) to take it down. This starts the cooldown timer right away.
    • The ice wall can be used to stop a weak enemy from running away or falling back or can be used by Mei as a defense mechanism for running away and blocking her opponent's path as she escapes.
    • The ice wall can have its individual columns broken if they receive too much damage, so be wary and prepared for if the enemy breaks it apart.
    • The Ice Wall can stop several ultimates. Reinhardt's Earthshatter, Pharah's Barrage (if placed properly), , D.Va's Self-Destruct, and Orisa's Supercharger. However, ultimates like Tactical Visor and Dragonblade can go around the wall. Roadhog's Whole Hog deals enough damage at a time to break through the wall, and Dragonstrike can pass through.
    • The Ice Wall cannot obstruct or delay the payload. The payload instantly destroys any deployed object it hits when moving.
    • Mei can free herself from Junkrat's Steel Trap by placing an Ice Wall directly underneath herself.
    • It can be used for crowd control. The first, to completely block an entrance. The second, to split an oncoming rush of enemies to better pick off the first few before their teammates can back them up.
    • Unlike other interactions with deployables like, Torbjorn's turret, and Orisa's Supercharger, placing a wall underneath Symmetra's teleporter simply raises it.
  • Use the Blizzard ultimate on map objectives to freeze enemy defenders.
  • Although the drone that produces the Blizzard field is visible, shooting it has no effect.
  • Blizzard can be deflected before it hits the ground, so be careful when using it near Genji.
  • Sometimes throwing the Blizzard into the air can be effective, as normally, people expect the drone to hit the ground right away.
  • Many people have various counters to escape the Blizzard. Reinhardt's Charge, Reaper's Wraith Form, Zarya's Particle Barriers, and Sombra's Translocator, to name a few, can escape the radius quickly.


  • Mei was announced on November 6, 2015, alongside D.Va and Genji. She was added to the Closed Beta three days later on November 9. Before that, she was teased in an in-universe story, Mei's Adventures.
  • Mei started as a character called 'Frostbite' and drew inspiration from ice carving festivals in northern China.[7]
    • Mei was originally meant to be something like a bounty hunter, but a piece of concept art by Arnold Tsang steered her character towards being more of a normal person.[7]
  • Mei has the most emotes out of all the heroes.
  • It is an ongoing theme that every game by Blizzard has at least one character with an ability named Blizzard. In this case, it's Mei.
  • Mei was the first hero to have a skin redone due to large amounts of criticism from fans who stated that her Lunar New Year skins showed her having an extremely small waist and her back was at the point where it appeared caved in.
  • Mei's listed age (31) refers to her biological age. Since she was frozen for nine years, her chronological age would be about 40.[1]

Cultural References

  • Her Voice Line "You have to let it go!" and random line "Do you want to build a snowman?[8] are references to the 2013 Disney film Frozen.
    • The movie Frozen and the line "Let it go" were mentioned multiple times in the Overwatch Visual Source Book as a joke between the developers.
    • Mei's Voice Line "You have to let it go" is changed to "You have to let it snow" when the Winter Wonderland-exclusive Mei-rry skin is equipped. This is a reference to the popular Holiday song, Let it Snow.
  • Mei will quote two lines from a poem A Song of White Snow in Farewell to Secretary Wu Going Home by Cen Shen, a Tang Dynasty poet, at the spawn of any snowy map such as Volskaya Industries or Nepal. The two lines are: "忽如一夜春风来,千树万树梨花开。".[9]
  • The "Science This" voice line may be an indirect reference to the theatrical release trailer for the 2015 film The Martian, as the protagonist, astronaut Mark Watney quotes "I'm going to have to science the hell out of this".
  • Some of her skills may be a reference to Blizzard's Warcraft franchise. Cryo-Freeze seems to be a reference to Ice Block, an ability the mage class can use for exactly the same purpose (only it lasts 10 seconds in that game). Additionally, Frost Bolt, one of Jaina's mage abilities in Heroes of the Storm, is remarkably similar to Ice Spike.
  • Mei's dance emote resembles the "Hare Hare Yukai" dance routine from the first outro of the popular anime "The Melancholy of Haruhi Suzumiya."
  • In connection with protests in Hong Kong, some protesters have made Mei a symbol of protest in an attempt to have Overwatch banned in China.[10]
