"Hisss mind isss hisss own. He is still a "Dwarf". Consssider the garb assss a token of good will."
Char file; What I'm RP'ing and what it does (as to advoid accusations of ass-pulls and nasty surprises by playing with the cards on the table):
Species: Tyrannid
Strain: Winged Hive Tyrant.
Characteristics: 5.6m tall at full height (though it slouches to just over 4m), about 2 meters wide, wings folded. Really, really old, and has learned the intricacies of social relationships and a good deal of psychology by observing the population of future target-worlds with spies, and by munching on the occasional brain. Terrifyingly bright for a bug, with an intrinsic knowledge of physics (and, derivately, chemistry and biology) and strategy. Considers getting wounded/killed as an annoyance, needing only time to grow a new body or glue back a limb. Obnoxious, inquisitive and cautious, with occasional hints of sadism.
Abilities:
Monstrous Creature == Kiss armor-based damage mitigation goodbye, and don't expect to parry. Roll, dodge and generally move out of the way.
Main Synapse creature == The embodiment of the only thinking mind in the force; every other critter is run by remote-control, larger bugs acting like relay stations. Also means it's a powerful telepath/empath, with meager telekinesis.
Weapons: Lashwhip (enemies fumble in mele, Tyrant gets to swing first) & Bonesword plus a Stranglethorn Cannon (long ranged living gun with large AoE blast; binds targets in place with spiky tendrils, and can also do a lot of hurt)
Bio-Morphs: Acid Blood (take a guess) and Adrenal Glands (you get a 3.5 ton monster made of muscle, blade and armor charging at you at 60mph)
Powers (spell-like, single target): Leech Essence (you hurt a bit, I heal a bit) and Paroxysm (you miss; a lot.), plus Hive Commander (expect bugs; from everywhere).
Notes: Beware of other 'nid strains (as in look'em up on the Interwebz and see how fun having 3-4 Lictors and packs of genestealers sneaking around the place can be). If my char'll have to fight someone, though I hope not, it'll do it one-on-one (playing as a towering nightmare made flesh is a bit much on its own), so please, don't perform ass-pulls like "AoE time freeze + popping a magicaly null zone" or "i sumon 9999999999 iron goelms and atack", or even "I push my I.W.I.N. Button, and start casting FoF.", unless you want to have the ground and walls open up and be drownded by thousands upon thousands of little flesh-eating maggot-things, slowly nibbling you to death (I can also provide very graphic depictions on popular demand. Also, OP/topic moderator (That's you, Merchant) is obviously exempt. Locking PCs in Obsidian is the closest thing you have to a banhammer.). 'Nids dig; fast. They also multiply fast enough to make cockroaches look like prudes.
TL;DR: HFS meets the Zerg and graduates Magma cum Laudae from the Sauron Institute for the Criminally Vicious. Combat monster. Can get info (genetics and memory) by omnomnoming things, and has been a humanitarian for long enough to know what makes most people tick. Delights in being a prick.
