Nodulians are an extraterrestrial species who are apparently aggressive. On their planet, Nodulians spend most of their lives under water - been able to remain submerged underwater indefinitely. On planets like Earth, they need to regularly submerge in water with a high level of zinc in it to survive. They are also weakened by heat which would merely irritate a human.
For the Nodulian criminals that came to Earth after escaping from SAR TOP, many found themselves developing sinus problems as a side effect. This meant they would often have to get medicine or an inhaler as their symptoms mimicked asthma.
