When Ultra Hunter shoots a deer he can track it down by the blood trail. When he shoots a villain, he can track them down too. He hunts fugitives. He can find missing people. The police ask him to help because they could not find the missing person. Ultra Hunter was able to find all the missing people, then he went back hunting.
We killed the monsters. Now we got to find the missing person.
I found the missing person by my ultra violet power. I tracked him by blood.
