Doomsday was part of the 2nd wave of DC Superheroes action figures back in 2006 along with Superman, Supergirl and Bizarro. Doomsday stands approximately 6.5 inches tall to the top of his head. Just a little over 7 inches if you count his pony tail. He should probably be just a bit taller.
As you would expect, Doomsday has a lot of cool spiky bones protruding from his entire monster like body. Its mostly made with a soft rubber but all very well detailed.
The paint job is decent with some minor smudges here and there. There is some shading over his skin around his arms and legs. The face is very clean. Although you can't really see his eyes in this picture below, they are painted red behind the bones.
Comparing Mattel's Doomsday to DC Direct, you will notice right off the bat a size difference. DC Direct probably has the correct size but as far as articulation goes, Mattel wins hands down. Mattel's version has joints in the neck, shoulders, biceps, elbows, wrists, abdominal, waist, hips, thighs, knees and calves and ankles. One note, the bones on his shoulders do obstruct the shoulder joint movement a little but its not too bad.Superman figure from the same wave.
Overall, DCSH Doomsday is a cool action figure that is a must have if you collect the Superman action figures or the related Mattel DC Universe Classics toy line. Generally, Mattel has been doing a good job with these action figures and Doomsday is no exception.
Now, if you're looking for your very own Doomsday action figure, my favorite place to find him would be eBay. If you read my blog regularly, you will see that I am a heavy user of eBay, especially to find older toys that are no longer in stores.
