The original Katarina presumably became a Cronenberg in Dimension C-137.
At some point, Katarina was captured by command from the Agency Director, presumably because of her revolutionist father. She was killed, however, unbeknownst to him while he was imprisoned by the agency in America. The Agency Director lied about her being alive to force Jaguar into combat against Rick before they joined team against the agency.
- Though she never appeared in an episode, Maximus Julius Pauson, a character designer for Rick and Morty, released a character design of her and Jaguar on his Instagram-account
