Because this was the first in the 21st century line of action figures, it set the standard for those that followed. For instance, most figures are not really five inches tall. The Dalek is 5" tall and all other figures scaled to match the Dalek's height.
The Auton is articulated at the shoulders, elbows, hips, knees and neck. Two Autons, both with black jackets but different shirts and skin tones were available in a two pack. An Auton with a grey jacket was also available separately. All versions of the Auton had twisting fingers to (inaccurately) replicate their opening hands in the show.
Several versions of the basic Dalek as seen in Dalek and elsewhere have been released. The basic Dalek body features rolling wheels, turning head, elevating and detachable eyestalk and arms that are ball jointed and detachable. A version was available with Genetic Print and another with Mutant Reveal.
The Assault Dalek had a combination claw/welding torch manipulator arm as seen in The Parting of the Ways. The figure features rolling wheels, turning head, elevating eyestalk and ball jointed arms. The eyestalk and arms are removable to be compatible with the Genesis Ark playset. The Assault Dalek was later released in a darker bronze colour as a SDCC Exclusive. As with all of the Character Options Dalek toys, the paint deco includes a name Glyph.
