The way the Ratchet & Clank wiki capitalizes words has changed; therefore, this article should be checked, and, if necessary, capitalization should be fixed.
The Elite Hydra Tank was a boss encountered thrice in the Battleplex Arena challenges. It was an elite version of the typical Hydra tank, having a silver color, using electricity instead of fire, being much larger and having a lot more health. It still was vulnerable via it's versa-fuses, but whenever it activated a forcefield around it, a shockwave emitted from it that potentially could damage Ratchet while he was pulling the fuses out. A way to defeat it with only a wrench was to wait for its electric spinning attack then jump on it. A hyper strike could be used continuously after jumping.
