Looking at the list on ranger wiki of Zydenchi I'd say they're Gurumonite and Deinosgrander, so basically guardian spirit batteries given form.

Really looking forward to owning the Anky and Croc zords.

Still need Pachy and Ammonite though.

No, they weren't. They were Guardians. Basically original Voltasaurs that helped Bragigas repel the original Deboss invasion. They weren't seen combining with anything, so don't expect to see them in Dino Charge except in the flashback footage created fro Kyoryuger. They didn't get toys either so these are entirely American creations, and good ones.

And Pachy is actually from Dino Charge. He belongs to the Graphite Ranger, who was Kyoryu Gray in Kyoryuger. There was a Pachy in Dino Thunder, yes, but it looked completely different.

When I originally saw the Deinosuchus, I figured it would split in half and become 2 chomping arms for the T-Rex. Looks like I was half right. Tough to tell from just the tiny pic on the back of the box.

Also a minor thing, but I like the US Dino Chargers over Zyudenchi because of the added educational bonus of having the real dinosaur names on the backs.

Can't wait for the Deinosuchus Zord

Do they seriously have to do Dino Thunder remolds?! If they continue this pattern, there's going to be an orange Ankylo coming.

I noticed it was Dino Charge after I took a good look at it. But at first all I saw was purple and I thought D. Thunder instead of D. Charge.

...seriously, what is up with the pachy zord?
Does it hurt to make it show accurate?

Those are repaints.

We finally get a purple Pachy zord. :lolol
