Pythron

From Memory Alpha, the free Star Trek reference.

The Pythrons are the inhabitants of Pythro V.

Con artist Martus Mazur frauded an elderly Pythron couple in 2370 by getting their financial access codes and investing their money in his business, which promptly failed. The couple filed a complaint against him with Odo, who arrested Mazur. Under the influence of a machine changing the laws of probability, the Pythrons temporarily did not follow the charges, but they later changed their mind again, so Mazur went back to prison.
