My race, the Irha-Nrr, are a little _too_ helpful at times I think. A while back under the thread "Game Stories" I posted a chronicle of the game in which I developed their personalities, and they turned out to be militant pacificsts; they want all the fighting between empires to stop, and are willing to destroy every starship in the galaxy if that's what it takes.
A new race I've started fiddling with are serene sun-worshipping flowers; their personalities are unformed at this point but considering how the Irha-Nrr turned out I'm expecting them to declare jihad and start feeding enemy populations into black holes at any moment.
