Reason: Some notable Metroid species being implied their proper, broader tags.
It might be worth making a metroid larva tag for the most iconic Metroid form, for easier search purposes, but the other metroids are much less prevalent image-wise.
In the other thread, for the Zebesians, there's confusion about what differentiates Zebesians from other Space Pirates, but if you're familiar with the games you know that Zebesian is used for a very specific morphology; yes, Ridley is also called a Zebesian, but the standard enemies are how they are generally presented and defined. Of course, the Space Pirates are made up of many different species, so if any tag's existence is in question, it should be that one (but otherwise we wouldn't have a tag for the pirates on Tallon IV or Urtraghus).
