He's a creation of Brick Frenzy, who have a site of many different Lego creations.
Coming in at about 16 inches tall in robot mode, and approximately 2 feet in alt mode, Blackout is fully transformable, and modeled after the toy version.
You can see the Blackout gallery here.
I don't know about you, but it makes me want to pull out my LEGOs and start creating again.
