Talk:Black Hydra/@comment-1687225-20120622183427/@comment-1961216-20120623033312

The original hydra is incapable of movement and is only a minor enemy in a small area whereas the Black Hydra is very well capable of moving all across the map and is the primary feature of Ash Lake, other than its housing a covenant NPC.

The primary reason to list them separately is so that both appear in categorical listings. Enemies that are simply previous enemies with different health and attack output (e.g. basilisks, common Hollowed, respawning normal versions of previous bosses) don't even get a different name, let alone their own page.

The Black Hydra also has different drops than the normal Hydra, while other recurring enemies don't have this feature.
