LM-432 crab droid

Crab Droids are a type of Separatist battle droids, but they do not rely on blasters. There were two types of crab droid, one had four legs, and the ability to capture opponents in bubbles, and the other was a six-legged melee tank.

The first type saw action during an unknown battle, where three of these droids captured Aayla Secura, Voolvif Monn, and Agen Kolar. Anakin Skywalker saved them by destroying all the droids. It also saw action during the Battle of Coruscant, where it destroyed many ground vehicles by walking over them.

The second type saw action during the Battle of Utapau, where the crab droids were very efficient, being able to walk up the cliffs.
