If the inside of Gabutyra's tail is solid, then where does the combined form helmet go? Don't tell me it just gets tossed to the side or it doesn't come off, raising questions for some of the later combinations.

I believe i read somewhere that it stores between his legs in dino mode. which does raise questions about later combinations that leave the legs in robo mode but use a different helmet.

On the other hand, I do feel the filled tail looks better on the back of the robo mode than it did for the sentai version of the toy.

Interesting. Unless I am missing a combination, I wonder what those clips on the sides of the head are for. Tobaspino?

Also, Stego-zord sowrd cant form the shield, but thats not really something Ill hate it for, I dont remember it being used much anyway.

I think those are going to be the attachment points for Giganto Kyoryujin.

The only part that connects to his head though is the tail portion, with a bit from Bragigas, but I think those connectors will also be how we get Tobaspino.

While it is true that only the tail portion attaches it's also rather large and potentially rather heavy so extra support would be necessary to keep it within US toy safety regulations. Also, While it is possible that it could be for Tobaspino, it doesn't make too much sense as the parts exclusive to Tobaspino only attach via the head. The more I think about it the more likely it is that those clips are used for Bakurestu Kyoryujin.

I wonder how he is going to size up with the other megazords. I hope bigger than legendary megazord.

Its entirely possible that they still combine using the batteries since most zord builder ports are actually in the shoulder. So in this case you would rip off part of Gabutyra along with the attached zord for zord building.

The main reason why I think this is because of all the bulk surrounding the connections between Gabutyra and the arm. Its as if they are using a duel clip system to support the battery and zord.

Another possibility is that batteries have zord building ports on them.
