Scroblin

Scroblins are oversized, degenerate goblins which inhabit an alternate dimension. Eons ago a tribe of goblins became stranded in a dark dimension. Over thousands of years the dark energies twisted the already evil creatures, making them horrible and aggressive.

Trogoblyn

Trogoblyns are large, malformed, cave-man Goblins. They are generally larger, meaner, and stupider than normal goblins, more prone to resort to brute force and violence. Their smaller cousins tend to use them as cannon fodder.

BugBear

BugBears were original creatures in European myth, similar to Brownies, Nixies, Hobgoblins, and other forest creatures. BugBears were envisioned as large, hairy monsters that would abduct naughty children. In modern fantasy fiction, they have become a race of larger, stronger, deadlier Goblins, usually acting as the "boss" of a group of weaker troops, and beholden to a superior (evil) power.
