A lot of these Bounty Hunters will be of species from the later parts of Omniverse, most of which are canonically unnamed. I'm going to throw in my own species names, and maybe we can discuss some too, but we've got to make these names sound as fancy and scientific as possible. Can't make it too simple.
Astrodactyl's species will be a Pturbosaurian, since that's kinda-sorta close to official. Not that it matters since none of the Bounty Hunters will come from Terradino. Or Apploplexia.
There are also species not listed on the wiki but on other sources. Jury Rigg's species and Eatle's species for instance to have official names.
And we'll need to avoid putting -sapien on everything. I mean, we can put it on one or two of these guys.
