One of the most prized, and almost lost, Predator tank patterns is the Deimos Pattern Predator Executioner, which mounts a rare Executioner-pattern Plasma Destroyer. This ancient and powerful weapon fires a series of sun-hot plasma blasts capable of incinerating flesh and blasting apart even power armour with contemptuous ease. Only the forge world of Ryza is still able to manufacture the advanced photo-plasmic cells needed for the Executioner weapon, so many chapters whose Techmarines have sufficient skill and knowledge replace the Plasma Cannon with a Heavy Conversion Beamer.
This turns the Predator Executioner into an extremely powerful siege unit and long-range tank destroyer, but this firepower is gained at the cost of manoeuvrability and increased vulnerability to short-ranged attacks. That such a modification carries a long-standing seal of remittance from the Adeptus Mechanicus speaks of cataclysmic battles in a forgotten age, in which such devastating firepower was more common, and more necessary.
The Deimos Pattern Predator Executioner is a multi-part resin and plastic kit containing two turret weapon options along with both lascannon and heavy bolter sponson weapons.
