Kobolds are iconic D&D creatures. They are intelligent but weak, and are typically encountered by starting characters to work their way up to bigger and badder monsters.

Kobolds are creatures from Germanic mythology and have been equated with goblins, or other mythological creatures.

In D&D terms there are lizard like humanoids. Some DM’s make them organized to the point of being a great challenge to even the toughest player characters.

One very famous group of koblods, Tucker’s Kobolds, were discussed in an edition of Dragon Magazine.
