So, like Zangya mentioned, I kinda see the “Studio” version of her as someone trying to start over after an abusive/tragic past. We don’t know much about what her life with Bojack was like, but given how it ended we can assume it wasn’t great. Studio Zangya is someone who takes a lot of pleasure from her new life of freedom and fun, and I definitely read her as someone who enjoys being on top/in control (as we’ve seen in her relationship with Gohan). Cocotte, on the other hand, doesn’t have those regrets and doubts from her old life. Since she comes from a sort of pseudo-military group, it makes sense to me she’d be used to and comfortable with surrendering control to a commanding officer. So here we are. ^_^
Also, here’s the Q&A video I did last month, if anyone’s interested:
