Well Gao God is still composed of 5 Power Animals so I kind of give it a pass.

The Panda could be easily made from part swapping Gao Bear and Polar but I'm a stickler for authentic, JP only release. Though I did consider picking up the weird Purple Bison that came with the Ultimus Megazord. Use it as a stand in sort for GaoGaur (Cow).

Not so far no. But the song they sing does appear in an episode.

Sounds good to me. But you know, being MMPR, the Red is going to be American

It's definately one of the best Sentai series' we've had in a while. It has the story, and the characters, the villians.

You, Sir, have excellent taste in Sentai villians! The thinking is yes. That that will be his ultimate attack, firing each battery like some grand missile of Dino-Bravery.
