Larger Barbarian figures?

Is Leviathan a manufacturer or an adjective in this instance? 

That would be the old Leviathan range of miniatures from Scotia Grendel, whose website I can't access right now for some reason.

  You're not wrong asking that! Even more interestingly, they were sold as being 25mm too...

Correct and seconded; site seems to be offline, or I would have included a link...

Enigma Miniatures make some outstanding barbarians that are a good head or so taller & suitably bulkier than just about any other mini maker. They are pretty pricey, but high quality pieces from a small company usually are.

GW chaos Marauders et al - lots of multi pose options, might need head swaps though?

Have you thought of some heroclix figures the hulk ? I converted some to my chaos army.

Yeah, that's not a bad idea at all.  I've already ordered enough super mutants for my purposes probably, but I may look into that.  Maybe if they have some bigger Hulks it could work for a behemoth.
