Mindhunter.
One who hunts the mind of his opponent and brings him face to face with all the dark and dirty secrets which had all been buried as they did not want to face them.
True, that 'dark and dirty' part might not apply to all, but it was pretty much true that everyone had some or the other thing that was still stowed away, never to see the light, as it would just affect the person in question too much if it was came in the forefront of their mind.
Right now, the Warrior was going through a vision where all of the people whom he had killed and all the things that he had done which he regretted were all surrounding him, threatening to swallow him whole and throw him into an endless pit of disgrace and shame.
In this state, anyone would be defenseless, and the Mindhunter would be able to get an easy victory.
