Zyuden Sentai Kyoryuger (2013)

They have the same producer and other connection that you see when watching king-ohger. They are both fun shows

After Tokumei Sentai Go-Busters, Kyoryuger is a return to the colorful fun of Gokaiger. There are an abundance of things to keep your eyes captivated and this really is the first sentai series I've seen post-Gokaiger to sort of capture the fun and spirit of it.

It's the 36th sequel of the series from Super Sentai right after Tokumei Sentai Go-Busters which is the 35th sequel. If you would like to watch the super sentai series chronologically.

It's the 37th sequel of the series from Super Sentai right after Zyuden Sentai Kyoryuger which is the 36th sequel. If you would like to watch the super sentai series chronologically.

It is very clear that Ryusoulger was trying to bank from what made Kyuryuger profitable. From the Dino motif to the high energy dancing in the change to the exact same color scheme of the core team and sixth.
Other ways they were similar was that both teams were not trusting of each other at the start (The Kyoryugers didn't want to give away their identities at first and Ryusoul Black and Green didn't want to work with Red Blue and Pink), their sixth rangers didn't want to join with the team immediately and they both had villains that had a human inside them which later sided with the team to help.

It's the very first Super Sentai series what made many of it's successors possible. If you want to watch the original first season of the Super Sentai series.
