I believe the answer is: He's constantly having nightmare on his sleep and constantly do a violent outburst as if someone is trying to hurt him.
All of those signs point to a post traumatic stress disorder. This could only happen if in his personal mind, he still believed that he is on a battlefield, even if now he is currently at home. The horrible experience that he face on the battlefield still haunting his mind .
That ans is Battles did that help
Rhinoceros and triceratops both have horns
The rebelled, boycotted, and stood for their rights as humans
I think the answer would be executive power.
