Fearless
Gale is fearless because he put his name in reaping 42 times for his family, because his family needed food.

The commander takes him in a square and starts whipping him with a belt. Eventually, Katniss, Haymitch and Peeta stop the commander from whipping him.

His dad and Katniss dad in the same mining accident, so now he works in the same mine. He in The Hunger Games Mockingjay Part 1 is now a soldier for District 13 after the bombing attack in District 12 in The Hunger Games Catching Fire. So after all that work in the mine it gets attack sent from the capitol or President Snow. So him and other rebellions like are going after Snow for what happened in District 12 .
