Is it even a word? Or is it just another misspelled word?

I'm playing FFI (NES) right now, and I ran into a couple of Kyzoku's. I got the sudden urge to type it into a Japanese-English (online) translator, and nothing came up. Then I made an educated guess that it means "pirate" in english and I typed it in to translate it into Japanese and it came up with "kaizoku".

Then I tried translating "renzokuken" into english and again, nothing. I've tried a few other variations in japanese that would've sounded the same and still haven't gotten anything. I swear, the japanese-to-english translators that they have working on these games really need to be replaced with people that aren't afraid of translating EXACTLY what it means in english. I know some stuff doesn't have a direct translation, but they could at least TRY.
