After looking through the choice of races Star Trek Online has to offer players at the moment (Alien, Caitian etc) I have been working on creating a fan made race based on the rabbits of Watership Down, of which I call them Lapinean which is an extension on Lapine, the rabbit language. I think they have the potential to be played as Federation and Klingon characters, and they would make good tactical and engineering officers.
The Star Trek Online Race Traits I have chosen are Acute Senses, Natural Immunities and Sure-Footed.
No reason to disallow rabbits as even a sperm whale can build a starship and explore the outer regions of space. Good job the Borg never met them, unless the B'gers are actually Borg whale probe ships!
