Essex goblin

The Essex range of goblins are a little undersung, I reckon. Yes, they're fairly primitive. But they've got buckets of charm. Rather than echoing Tolkien directly, they're more akin to the goblins of George MacDonald's The Princess and the Goblin - which in turn was the ur-source of Tolkien's orcs.

The direct inspiration for the range, though, appears to be Down in the Dungeon.

With his plate armour, this fellow doesn't really belong in Middle Earth. But in D&D, he and his ilk will make a nasty surprise for the party. A mere goblin becomes quite a different proposition once he's acquired a couple of hit dice and armour class 3.
