I have a range of different inspirations or rules surrounding my character names!
Alcots- named after different plants n stuff like that. For example, three Alcots in my comic are named Bush, Bloom, and Sprout. Less creative, though still consistent. Rip Bush she got a dumb name.
Neowis - named after Russian words relating to them, such as Bednyye and Strakh. The only Neowi that breaks this rule is Ruin, but she has a much different role than other Neowis and thus has a Guardian-centered name
Guardians - Named after mean words. Ex. Cripple and Chaos. It's a strange pattern I've developed, since they're meant to be incredibly helpful!
Cahros - Mainly Asian names, since the species is found within Asia. Though, mostly Japanese, as that's where they're the most commonly found. Ex. Eito and Masahiro
Latlows - Based off of latin words, even if random, such as Furrure and Dicere.
All other characters have human names or really unfortunate names, such as Moss cuz.. He can grow moss on his body. Very creative, I know. Though generally when I make a new important species I like to make patterns with their names hehe.
