Hi guys,
This figure does not exist on yojoe.com, I think the date on his foot looks like 2004 or 2006? Helmet is not removable if that helps. If you guys could help me out on this one that would be great!

your pic does say Hasbro tho...... That would place it near the Valor vs Venom era of joes.

Looks very similar to the Valor Vs Venom Shipwreck mold...especially the legs. I am sure Sean will know...

It's a repurposed GI JOE mold used for THE INCREDIBLE HULK movie toy line to create Hulkbuster army figures. The figures had helmets glued on, their heads are unpainted.
That one was part of a boxed set called Epic Tunnel Clash that included 3 of the Hulkbuster figure and a Hulk (Goes for around $30 on ebay nowdays)

Yojoe has an entry, it's easy to overlook.

Other Hulkbuster figures reused different Joe molds from the early 2000's, one had a Tim Roth head and another had a helmet molded on. There were some new preposed 4" figures used, too. A Hulkbuster Humvee was made from a GI JOE Humvee with some modifications.

The line was heavily clearanced. Many loose figures were available from China for years, The Emil Blonsky one might still be (Tim Roth's character).
