Mr. Naga is a man with short purple hair and glasses. He is sometimes shown without his glasses and in a button-up shirt and tie.
Mr. Naga is a strict man, he seems to be very worried about his son's power and he sometimes reminds him to be careful as this power can kill people.
He thinks that superpowers should not be used on people because it's dangerous.
He had a deep hatred of the criminals and said that if he saw one in the street, he would beat him to death without even calling the police. He thinks that sitting and watching a crime is also a kind of injustice and that is even more wrong to let a criminal go.
For him, if his son goes to jail because he beat a criminal to death, he would still be proud of him.
