With my Tyranid Gallery up and running, I'm happy to show you my first focus on a mini I made. This one is my personnal favourite tyranid model so that's why she's the first to be under the lights here.
Let's get back in time first, when the first tyranid codex was unleashed on the unsuspecting Imperium. When the first hive tyrant was released, it was stated that it was a kind of "male", so wanted a "female" tyrant. This being is supposed to lead planetary assaults for my fleet, has some limited spawning capacities, it is a main synapse creature, so it must be a great psyker, and of course, it had to get wings, even if at that time (1st nid codex) that was not in the codex. A queen was done by a friend as I had not the skill to do it myself.
But end 2005 I had learned to enjoy converting so I redid it, using mainly old parts to show it is the oldest being of my fleet. It is mainly an old fex body with epic hierophant arms, legs and lower body/tail and zoanthrope head. Tentacles are to give a cthulhu-like look (my fleet's named 'Cthulhu'), and to taste the preys. Notice the ovipositor at the end of tail, in a facehugger's fashion... This beast spits bio-plasma in a good old way, like screamer killer, the 4 claws providing electromagnetic fields to guide the plasma. Can fly in any environment using warp wings.
