These are the main original characters:
- Captain Zalia Smith
Cap is 23, she has been Captain since she was 18. Her parents died when she was a kid. They were both banished from their clans and after many years of living in the Underground, they died on a mission at the hands of the grounders. Zalia has a little sister and they were raised by her mentor Osias. The most important thing for her is the survival of the human species and she makes constant sacrifices for that cause. Her whole life she has been trained to lead her people and now that she's the leader, she has been making lots of good changes to help her people, but most of all the human race. She's very talented with weapons, especially handguns and knives.
- Marian Smith
Zalia's Sister. She's a rebel. Marian is 20 years old. She has been under Zalia's protection for so long, but she still wants to see things she has never seen before. Even if it gets her in trouble. She's part of Zalia's army, even when Zalia didn't want her to be. She passed every single test to be part of it, so Zalia couldn't oppose. She's a lieutenant under Osias. She was trained alongside Zalia, so she's perfectly capable of defending herself.
- Osias
Zalia's mentor and second in command. He raised Zalia and her sister since their parents died. He was the best friend of their dad. Osias is a general in Zalia's army and has taught her and Marian mostly everything they know. He lost an arm in battle when he was young and now has a bionic arm.
- General Gunner
Husband. Father of two girls and a boy. Combative personality. Always fighting for what he wants, and not really caring about what others think. Trusted by many people in the community. Always puts his family and his clan first. In charge of 40 men. Not loyal to Cap. Doesn't believe in grounder culture since all his ancestors trail back to the military personnel that lived in the bunker. They have no grounder bloodline. He has only seen the bad part about the grounders.
- T. Michaels
Genius engineer. Master in technology. Cap's best friend. Grew up with Cap. Free spirit. More driven by her emotions. A little bit careless.
- Martin
He's a brain. Master mechanical engineer and also a doctor. T. Michaels' mentor. He's been loyal to Cap even before she became the captain. He was also a friend of her father. Has a fatherly feel to him, but at the same time, has super rough edges. A little doucheie or judgmental sometimes. It's something that he doesn't like when it comes out, but it just does.
