Close, the boss he is on right now (just tuned in) is looking like one of the last... if not the last. If you are familiar with Marshall's badassery, you will realize what it means that he is now on his 8th attempt at this boss. Ouch.
EDIT: 12th try. This boss is easily the most brutal I have seen yet, it is making me scared of ever getting there.
EDIT2: Finally beat him after about 20 tries maybe?
Spoiler: show
