Hot Rods entire upper body looks too big. It's weird.
He definitely could use some sort of collapsing on the hood. It's odd. He's very angle dependent. From a lot of frontward angels, he looks great. From the back he looks decent too. Catch it on a side angle and the squareness of the chest becomes hugely apparent. I'll be interested to see how it looks in most display uses. The fishing pose looks nice at least.
I'll get him because he's an MP and they never go down in price, so why not, but I'm not excited about him as I'd like to be. The fact they didn't go with movie style super magenta is kind of a downer as well. He looks pretty good for what he is, but definitely one of the weaker car MPs.
Shockwave is brilliant. I like the way he integrates the barrel for a perfect transformation while also offering the stand/backpack if you want to cover it up. The head sculpt is amazing as well. The inclusion of the mini-shockwave and alternate clear hand parts are perfect. Takara really killed it with him. Now just hope MP Screamer and the future Megs 2.0 will be able to use mini-wave. I'm sure they will. I have zero complaints. I cannot wait to get him.
