A-120 is a quadrapedal entity, each of its four, clawed feet are encased in a tough exterior of metal which is what causes the metallic banging/thumping noise as it approaches. A ball and chain is attatched to one rear leg, causing it to move slower than the other entities. The additional metal to its front claws make them much more lethal. A-120 shows similar qualities to Ambush as both entities rebound at least twice when attacking. A-120's body is a ghostly greyish transparent colour.
