In order to reach Haddon Marr you'll need to take one of the green mushroom jumps up to the platform with Haddon Marr on it.
As far as loot goes, Narp (Hyperion Sniper) is the only item on Haddon Marr's dedicated loot list. This item is unique to Haddon Marr and is difficult or impossible to find on other enemies throughout the Bounty of Blood DLC.
