The individual packs from the Build Custom line come with a bunch of adapters for different connectors, so yes, they can go on any HG gunpla that you can remove the existing backpack from (for example, they can't work with the Reborns because the main thruster/Cannon mode chest cannot be removed, so it gets in the way of the new pack). The packs that come with their respective gundams, however, don't come with the adapters. I actually demonstrate the different connector types/uses in my Dark Matter Booster review:

You do gunpla reviews? I shall check out your vids some tme soon.

I researched and learned the english dub did not dub one episode of Gundam 0079, does any one know the reason why

Yeah, sometimes. I rarely can afford to buy gunpla, though, so they're few and far between. I still haven't uploaded my Full Armor Unicorn review, however, so that'll be coming sometime...

All this talk of Build Fighters reminded me I never took/shared pics of my Renascita.

Your voice is a lot deeper then I expected

How is the GP base?

The first time I heard it on a recording it was deeper than I expected, too :lol. I really should be a dramatic movie narrator or something.

It's about as good as it can be for a big hunk of light grey plastic I guess :lol

I don't have much experience with Gundam stands, but it's pretty sturdy. My only complaints are that I wish the arm was longer and the data sheet was a bit sturdier. All it is is a piece of paper that you need to cut out of a template.

I think that the other gunpla in BF should've come with pre-filled screens for the GP Base so you don't have to make the screens for the in-show gunpla yourself. Then the blank one with the actual Base could be reserved for your custom gunpla.
