The pilots who control the War Robots can also be main characters. Their skills, strategies and personalities play important roles in the stories. For example, a brave and innovative pilot might lead his War Robot to victory in a difficult battle. Some pilots might be more cautious while others are more aggressive, and these traits can greatly influence the outcome of the stories.
The main character is Harry, and then there are the robots. We don't know exactly how many robots or what kind of robots they are yet, but they play a significant role in the story as they are in the title along with Harry.
There was a war robots pilot who started as a rookie. She was assigned an old and less - equipped robot. But she was determined. In her first mission, she had to rescue a group of stranded soldiers. She studied the enemy's patterns and noticed they had a blind spot during their patrols. She sneaked in during that time, retrieved the soldiers, and on the way back, she even managed to disable a couple of enemy robots using the limited resources of her own robot.
Since I'm not familiar with the book, it's hard to say who the main characters are. But they could be humans who are involved in the robotics industry, like engineers or scientists. Or perhaps there are some special robots that are the focus, such as a robot detective or a powerful combat robot.
Obviously, the three robots are the main characters.
I don't know for sure as I haven't read the story. It could have inventors as main characters, the people who were behind the creation of the first robots.
The main characters could be the student robots. For instance, a clever robot named Robo - 1 who is always at the top of his class.
There could be the scientists who create the killer robots. They might be the main characters as they are the ones starting this whole situation.
Definitely Twilight Sparkle could be a main character. She is intelligent and her magic skills would be useful when dealing with the unknown world of robots. Also, a friendly robot like B - 12 (from a different robot - related story) could be a main character. They could form an unlikely duo to explore their combined world.
One interesting story could be about a War Robot that was damaged in battle but managed to self - repair and turn the tide of the fight. It showed great resilience.
The soldiers are often main characters. Both the American soldiers and the Vietnamese soldiers had their own stories, their fears, and their hopes.
