Generation 01 and 03.
Designed as a heavy weapon platform, the Mark One Special Weapon casing was used on battlefields by the first Dalek Empire until it was replaced with the sleeker, more advanced Mark Two model. The initial design for this casing was deemed a failure, as a design flaw in the initial run of meant that each time the weapon system was fired, a backwash of radiation flooded the habitation module causing mental instability and further mutation in the occupant of the casing.
The sole survivor of this batch became fully self aware and independent – this independence made it an ideal leader for the most dangerous and suicidal of missions. The unit was hated by the other Daleks, due to its impurity. In an encounter with Davros at the beginning of the Dalek Civil War, the "Abomination" turned on its allies and joined with Davros. Davros saw the benefits of the casing, rectified the flaw and produced his own heavy weapon units to supplement the firepower of the Abomination.
The skirting of the casing is similar to that of standard Dalek casings. Above the usual fifty-two (52) sensor globe arrangement, the top half of the casing was on a pivot. This allowed the Dalek a three hundred and sixty degree field of fire. The design of the dome section varied drastically from normal casings. The dome contained little more than a targeting package – battlefield telemetary was sent to the casing over the communications net from other Dalek units. This casing did not allow for sophisticated environment sensing, despite the standard number of sensor globes.
This casing did not feature the usual arm attachments, instead a single over-sized energy cannon protruded from the mid-section. Power was fed from the reactor in the skirting, with the conduits passing dangerously close to the habitation module and it was the conduits that supplied the energy that had the flaw in the first batch of casings. The habitation module remained in the mid-section, with a nutrient tank beneath in the static base module.
The Mark One Special Weapon casing featured an over-sized power generator that was subject to radiation leakage. The majority of the power produced was channelled straight to the weapon system and the motive unit did not allow this casing to travel at the same speed as standard Dalek casings. The motive unit installed in this casing did allow for levitation of up to twenty-five centimetres, however. In most cases, the creature inside would simply destroy any obstacles in its path rather than attempting to go around or over them.
