I met my first Deathclaw in middle school, playing Fallout on a friend's machine, and I fell instantly in love with these "Dragons of the Waste." It was an honor to tackle them for Fallout 3 - sourcing from both the originals and the concept art of Adam Adamowicz - but I'm proudest of my Fallout 4 redesign.
To improve upon their F3 counterparts, I gave the newer ones thicker, more armored skin; shorter, strong-looking claws and hands; a bull-like redesign to the horns (to suggest the ability to ram); and a thicker tail - heavy enough to act as a counter-weight when it ran. It's important to note, too, that the Deathclaw is not a mutant, but a hybrid bioweapon created by the US military. To that end, I incorporated chameleons, alligators, bulls, panthers, serpents & lizards into their design.
I love him.
