How do you say four headed beast in Greek?

There isn't a single perfect translation for "four-headed beast" in Greek because it depends on the context and the nature of the beast. However, here are a few options, ranging from literal to more evocative:

* τετράκεφαλον θηρίον (tetraképhalon thērion): This is the most literal translation. `τετράκεφαλον` (tetraképhalon) means "four-headed," and `θηρίον` (thērion) means "beast" or "wild animal." This is a good general option.

* θηρίον τετρακεφαλίας (thērion tetrakephalias): This uses a genitive form to slightly alter the emphasis, literally meaning "beast of four heads."

The best choice will depend on the specific context. If you're talking about a mythical creature, a more descriptive phrase might be better. If you can provide more context (e.g., from a book, myth, or game), I can give you a more precise translation.
