Lo Hin Shen is assigned to the Shatterdome in Hong Kong alongside Xichi Po. As the pilots of China's first Jaeger, Horizon Brave, the two are tasked to defend the coastline of Hong Kong from immediate Kaiju threats.
In 2019, Lo Hin Shin and Xichi Po accompany American and Australian pilots, Yancy Becket, Raleigh Becket and Herc Hansen to Manila when a Category IV Kaiju attacks the city. Though Horizon Brave is overpowered during the fight, Gipsy Danger and Lucky Seven come to Lo Hin Shen and Xichi Po's aid. The three are able to kill the Kaiju in a combined effort with their Jaegers.
Later during the war, Lo Hin Shin and Xichi Po are deployed in Lima where they are killed in combat by a Kaiju that destroys Horizon Brave.
When asked, Travis Beacham confirmed that Lo Hin Shen and Xichi Po were the pilots of Horizon Brave.
The sex or gender of either Lo Hin Shen or Xichi Po is never addressed by Beacham or Man, Machines & Monsters.
