You stand before a Klingon, unarmed... and get sliced open.
Tosk... you are correct! It isindeed "THE JEM'HADAR".
Explanations...
1. Went far, but stopped dead... The Odyssey went to the other side of the galaxy, but was quickly destroyed. Also, an odyssey is a journey... usually going far.
2. Not too tasty... Quark thinks the jambalaya is disgusting due to the bugs getting in it.
3. Not easy to do on your own... Jake tells Nog it's not easy making course corrections manually.
4. His next choice did not work out for a lot of people... Jake's second choice of a science project, doing a planetary survey in the Gamma Quadrant, proved fatal fof the crew of the Odyssey.
5. Greed came in handy... Quark tried to replicate Eris' collar so he can turn a big profit, but discovered it was just a complicated lock and discovered her real plan
6. A history lesson... Quark reminds Sisko of human history. (I'm betting this is the clue that gave it away.)
Your turn, Tosk.
