Notes:

Title is a rough translation of some of the kanji in pic. Okay, long story short there was an Japanese-only audio drama CD that served as a prequel to the anime released as a tie-in to Mewtwo Strikes Back that establishes more backstory and lore about Team Rocket, revealing that Giovanni's mother was its original boss and founder. Jessie's mom was one of the original members and vanished on an expedition to find and capture Mew, leaving Jessie an orphan.
