A friend of mine, Chabons, who is a big fan of Universal Century Gundams as well was able to acquire a 1/35 Jumbo Grade Zeta recently. I asked his permission to post the photos here so everyone can see the big difference in size. This information will help those who are planning to buy the Zeta kits as well… JUMBO is indeed the correct word because this thing is so big that a PG Zeta Gundam looked like a 1/100 version.
Here is a little description of the 1/35 Jumbo Grade Zeta
Bandai’s first fully transformable Jumbo Grade action figure can switch between its Mobile Suit and Wave Rider modes (transformation will require detaching and reattaching some of its parts). This humongous figure stands nearly twice the size of its Perfect Grade counterpart in Mobile Suit mode and weighs a hefty 4kg out of the box! Made of soft vinyl and ABS, Zeta Gundam is movable in at least its neck, shoulders, elbows, and knees, and comes with its signature beam rifle (assembly required).
twice the height of a PG Zeta indeed… around 2 feet.
The wave rider mode.
It is like the PG version can ride the Jumbo Zeta Wave Rider mode like RX-78-2 does with his G Armor haha.
Oh well, that is all for now. Hope this information helped you in any way.
