Xenology Tyranids 4 HQ Tyranid Prime

Starting Abilities:
As the best a Tyranid Warrior can get, the Tyranid Prime has T5, 3W and a 3+Sv. Equipped with a middle range waepon and scything talons he the weakest HQ choice, but excells in his own way. He is an independent char and raises WS & BS of a unit Tyranid Warriors he joins. And of course he is a Synapse Creature and has the Shadow in the Warp rule vs psykers.

Options:
With his 4A he has the option to get a pair of boneswords ... no Sv for the enemy and instant death test with 3D6. Thats just what you need! Go and chase some Characters! If you don´t like this, you can also choose between rending and one bonesword & lash whip. Which way do you want to go? Change the Devourer for rending or scything claws, maybe spinefist or deathspitter? You can also give him furious charge, poisoned attacks or regeneration.

Examples:
Shooty Warrior:
Give him a Deathspitter and join a large Tyranid Warriors unit, so they can benefit of the increased BS. Maybe a lashwhip for stealing the attacks from charging enemies.

cc Assassin:
Join a Tyranid Warriors unit to increase their BS&WS if you want.
Pair of Boneswords to get nasty VS charas
Scything Talons for re-rolling each 1 on to hit rolls
Adrenalin Glands for furious charge (you won´t need poison any more)

Allrounder:
Join a Tyranid Warriors unit to increase their BS&WS
Pair of boneswords (you already know why)
Deathspitter (3 S5 shots at BS4 + some additional stuff from the unit you joined)
Furious Charge only in case you intend to charge something.

Conclusion:
This creature seems to be the weakest HQ choice but its just cool.
1. As a independent chara it can hide in units so your synapse can´t be broken so easily.
2. He is the only HQ choice which can choose 2 Bonswords and benefit from the 3D6 test against instant death
3. Your Tyranid Warriors get deadlier when he increases their abilities
4. He is a cheep HQ choice with multi effects and synapse function.
5. When he joins a large Tyranid Warriors unit, he will survive long enough (if you keep being in cover for terrain or Venomthrope) so you don´t need the regeneration he can get.
