Captain Johnson laughed "Nothing but what i read in the in the chapters logs. The Crescent Moon Dragons only fought them once when a splinter fleet of levithan entered our home system bot that was before i was a battle brother so i missed the battle. I read up on the different types and how they strip worlds of all biomass and use it to make new Tyranids. They also are a hive mind 1,000,000s of bio weapon beasts all of one mind and purpose. I read anuff to know I'd rather face a full scale Ork waggha then fight those bests. Orks can be broken of will and run but Tyranid....<br/>We may be fear incarnate Tobias, but Tyranid know no fear."
