That's an amazing cross over

Are the Gundams suddenly human sized in these crossovers?

Not that it matters, because this looks great. I can never say no to SD Riders and Gundam.

Neat. I almost want a PSP now. :p

It's less that the Gundams are human sized, and more so that the Riders are giant.

Even better! :lol

It's happened before:

The SD Gundams shown are usually depected smaller than your average human. An example is Captain Gundam from Gundam Force SD.

Nope, the Gundams and Ultras are person sized. This is a followup to the old SD The Great Battle series. It's not quite the same without Fighter Roa, though. It means this can't happen.

Yes, that is Compatible Kaiser. A super robot being piloted by Fighter Roa, Kamen Rider ZO, V2 Gundam, and Ultraman Powered.

Ah. I just figured the Kamen Riders were giant because that would involve the least amount of conspicuous size shifting. We need an SRC Compatible Kaiser last year. :D

Not quite the same, but kotobukiya made a model kit of already.
