I'll be honest, I only got the Flash as it was part of the two-pack with Red Death. I wanted to complete my Dark Knights: Metal villain team of Batman-Who-Laughs, The Merciless, Dawnbreaker, Red Death, Infected Superman, Crow Robin(s), Devastator, The Drowned, and Murder Machine. All of those have been released in figure form, except for the Drowned. I have high hopes!
That said, he's a nice-looking Flash! I like the longer lightning pieces, and how you can plug in lightning effects to him (sadly, they didn't include them in the two-pack...why?!?). He is based on the DC Rebirth design of Flash (translation: Lets and MORE lightning to his suit). Some notable differences are the background of the Flash symbol on his chest is just the red of his suit, and the symbol itself is bigger and bolder. There are four lightning lines emanating from his symbol and the figure has more ribbed texturing on the sides of the torso, legs, and triceps. The crowning glory is the angry face sculpt. So well done!
I can appreciate this figure, and it's got some good points and is in keeping with McFarlane toys recent quality and articulation. I also appreciate that the Flash is a workhorse character of the DC multiverse. He's always bailing people out and resetting the timeline some comic book artists and writers can do something new haha! Go Flash!
