A custom Tyranid beastie drawn back during 2nd Ed Warhammer 40k (like 10 or so years ago). You know, back when 'nids were the underdogs and most games would start with you losing every unit not already in cover (and half of those that were). God I hated the 12" blast templates possible with Cyclone Missile Launchers and the Overwatch ability.

I used the Charkadris here: http://www.furaffinity.net/view/3291100/

P.S. Looking at the "gender" box under submissions I couldn't help thinking, "Sex?! 'Nids don't have sexes!"

P.S.S. This is drawn on the back of a chart detailing the relative decibel ratings of various sounds. Probably a sheet from a science class. I was such a good student.
