Hero or villain?
Naturally, it's up to you how you choose to use Man Hunter in your game. He's a good mechanic with an understanding of superpowers, and a competent bounty hunter, so your characters may view him as a useful hireling... and it is only once they know him that some of his other baggage comes to light and provides a source of adventure.
In terms of the fully-developed character statistics, Man Hunter is well done. The background write-up contains some good ideas that have been thought through and the actual presentation has been improved from the original presentation of this product, giving us an interesting and complex character who deserves to be viewed as a lot more than the aggressive thug he appears to be at first glance.
Enjoy introducing him to your player-characters, watch the fur fly... or perhaps a friendship being forged. He's the sort of guy most other guys will love or hate at first sight, or maybe both.
