Looking at Ezquerra's rendition (above), you notice that few artists have managed to make Deadlock as demonic as he did; he manages to reduce the entirety of the robot's face to a murderously grinning maw. Ezquerra is also the only artist to intimate that Deadlock is made of something like rough, dark pig iron (neatly reiterating the "knight" feel). All later artists seemed to have settled on bronze or brass.

With Khronicles of Khaos, Kevin Walker introduced some more colourful bodywork, and also managed to skilfully re-emphasise Deadlock's grinning maw, at the same time reminding us that the Grand Wizard is a capricious, mischievous, dangerous individual...

As an aside, if you look carefully at the Dillon version of Deadlock in Red Planet Blues (above), you'll see that he's portrayed with organic looking hands and claws, leading one to the suspicion that Deadlock may be some sort of...creature encased in armour, rather than a true robot. By the time Walker takes up the reigns, though, you can clearly see that Deadlock is a robot, making this point moot...
