[@Prewiga]Sorry, I missed your post. I'll tell you the ones who would be common knowledge.

Basically, the original Big Mom, Beast and Blackbeard pirates have been replaced. There are new Yonko in their place, with the Red Hair pirates being the only one from the older generation to remain.

The new Yonko are: The Barto World Pirates (ruling from their massive, Strawhat themed amusement park in the New World), The Kid Pirates, known for their psychotic rampages and even more unstable Captain, and the new Big Mom pirates under Smoothie.
