Forgive me if this has been pointed out already, but I haven't seen it anywhere.
I like the CW Stunticons, but it kinda bugged me how goofy their big hands/feet looked just plugged into the top or side of their vehicle modes. Then I saw someone in a Facebook group point something out with Breakdown that caused me to look at the others more carefully.
Breakdown's big purple piece can be mounted more or less flush with his vehicle mode.
He has a little hole just under the spoiler
And a corresponding tab on the thumb of his big hand.
Plug that tab into the hole and you get this:
Offroad has a tab on his truck bed:
That lines up with a gap between the middle fingers of his big hand:
Plug them together and you get this:
Dragstrip is a little less elegant. His hand obviously plugs onto the post on the top of his car mode, but if you angle it like so:
The base of the thumb nestles nicely into this spot on the spoiler:
And the whole thing rests nicely against the top of the car mode:
I haven't found anything like this for Dead End though, His just seems to plug into the top of his car mode and sticks up there awkwardly.
