Bizarre Alien Locomotion: In many variants on the standard walking, flying, and swimming, certainly. Eliéra’s bluelife includes its tubefish, for example, which move via peristaltic pumping of water, not swimming as we know it.
Among sophont races, the chfssssc swim through solid rock thanks to what one might call an active metabolism, the ciamél turn into vapor in order to move, the codramaju ooze along on pseudopodia, the d!grith brachiate along artificial vines, the esseli use whatever locomotive organs they happen to have today, the galari have built in maglev functionality, the kaliatar can coil themselves up and roll like a mythological hoopsnake, the seb!nt!at may well be there already, the vlcefc are webs carried by their motile castes, and that’s just scratching the surface…
Proud Warrior Race Guy: Some people think of the kaeth, the draconic pseudosaurians with the heavy-metal biology among the Imperials, as this, but while they are certainly violent (er, kinesthetic) enough, their sense of honor also is comfortable matching the Empire’s general Combat Pragmatism and eschewing of Martyrdom Culture, and it ignores their technological development and their artistic and spiritual side – really, they more closely resemble a cross between a Proud Soldier Race (see original trope) and Warrior Poet.
And also, same disclaimer: while there are a lot of them in the Legions and finding work with security companies and mercenary outfits, they are also to be found in the many assorted other roles that society requires. (Even though they can still probably kick your ass.)
More likely candidates include the heavy-world linobir, who play it much straighter, and the kaliatar, who would like to think they play it straight, but are far too sneaky and devious.
