"Greetings! I am Zex, a katril from another galaxy - that is, a host species carrying a symbiote organism internally. This symbiote in my possession has been passed from katril to katril over generations, retaining the memories and abilities of previous hosts. The symbiote is fused with my reproductive organs and, via the provision of male seed, is both nourished and acquires DNA data of new species. It is the top priority of katril to acquire as much knowledge of all species as possible, and the symbiote creates hormones that force irresistible urges to help with this goal.
And this is my first time meeting someone like you! I hope you will assist me in my mission.... It's feeding time. :>"
I hope you enjoy my new character, largely inspired from a certain character on Star Trek DS9 ^^;
