Former UFC Heavyweight Champion Brock Lesnar has been on the shelf since losing the title to Cain Velasquez back in Oct. 2010 thanks to a second bout of the deadly intestinal disease, diverticulitis.

Shortly thereafter, Lesnar had surgery to have a whopping 12 inches of his colon removed. He's now officially "back" and ready to get back down to the business of doing the two things he loves best:

1. Fighting.
2. Tracking down live animals and killing them.

He'll attend to the former on Dec. 30 when he battles Alistair Overeem in a heavyweight match-up of massive proportions at UFC 141 in Las Vegas, Nevada. 

As far as his hunting goes, mixed martial arts fans will be able to get a firsthand look at how that aspect of Lesnar's life is falling back into place when he appears on "North American Hunter" on the Versus network this Sunday (Oct. 2). The 30 minute episode is set to run at 11:30 a.m. ET.

Check out a video preview of the show after the jump:

For those of you with an insatiable blood-lust and an unwillingness to watch the whole three minutes and 31 seconds, skip to to the 1:14 mark of the video to see Lesnar "take 'er down."

If you're squeamish, work for PETA or both, you'll want to sit this one out.

Any Maniacs planning on tuning in to watch the Brockness Monster "take aim?"
