B2 grapple droid/Legends

Based on the B-2 battle droid model, the grapple droid was a droid model specifically designed for the Separatists' siege on Coruscant, and General Grievous himself personally oversaw its modifications. Bigger and profoundly more vicious than its predecessors, the grapple droid was equipped with electrically charged, industrial pincers, which it used to crush the life from its enemies. The grapple droid excelled at close-quarters combat and its embrace was quite deadly.

These units were shut down after the end of the Clone Wars.
