Mei (Overwatch)

Mei is defense hero in Overwatch

Story
Mei-Ling Zhou (周美灵/Zhōu Měilíng[1]) 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 Watchpoint: Antarctica when a polar storm cut off their communications and left them stranded. They entered cryostasis to survive until a rescue mission was made. It had been approximately a decade by the time they were found. Mei was the only survivor, and Overwatch had been disbanded.

Winston recommended that Mei keep a journal of her travels. 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.

At some point, Mei saved a nest of endangered arctic wildlife from a collapsing glacier.[2] She is also often accompanied by her assistant drone: Snowball.
