Hydrobots are claw-headed serpentile robots created by SkyNet. They appear in Terminator Salvation and are deployed in rivers and lakes that humans can still use for consumable water. They swim rapidly and can leap great distances. Their claws can tear through metal and they use these claws and the small drills in their maws to burrow into human bodies and tear them apart. They can also kill using the long, sharp spikes at the ends of their tails.
