I am wondering how Speedor and Bear-RV got it on.

There's probably Cars fanfics like that...

Oh god Go-Onger makes me want brain bleach now!:lol

Well unlike GaoLion it's not just the legs. :lol It's practically all limbs and the entire body sans arms of GoZyuJin.

Not to go too deep into sentient robot sexcapades,

but she is the middle part of the Engine Oh Sandwich......

This is my favourite Gokai machine.

Pretty cool looking design. The combination looks really nice. Helps that it adds more than the others.

Thanks for making my brain cry even more, Den! :lol

Does anyone know if this will be released with Super Megaforce?

It's quite unlikely they'll not take advantage of a final combination. :D It's an excuse to sell a really large vehicle!

Wow the fully combined form reminds me of my two parrots when they are in their singing phase.
