Reading through the Legacy Megazord thread, reading through the comments about articulation, made me decide to do this thread. Tigerzord had articulation, that's true. Some of which was due to it's transformation than anything else. The Thunder Megazord however couldn't have that level of articulation and still be as show accurate as a lot of the Legacy items are. Because the Thunderzords are basically just armor for the Red Dragon Thunderzord, it's not a Voltron-Limb style combined robot. They could've, possibly, had some articulation with the original MMPR Megazord. But that to would've compromised stability.
Look at Combiner Wars Devastator, as an example. Watch Peaugh's review or any number of reviews done on the toy since it's release this month. The individual figures are extremely compromised for the sake of the combined robot. And as the point was made on Twitter, posing combined CW figures at all is a challenge. Especially Defensor.
Returning to Tigerzord however. That figure could have articulation because it's not a combined robot. It has an animal and warrior mode. And even when it combined all the limbs that are articulated fold up in some way. (The arms don't, I know). The legs however do.

Would I like an articulated Megazord? Absolutely. But they already gave the line to us, Soul of Chogokin. And then Retrofire. But a combined, articulated, Megazord? I just don't see that happening. And if it does I promise you the toy will suffer because of it.
