Yamato and Musashi share a rivalry that's pretty intense—they're constantly throwing insults and sarcastic remarks at each other. What's interesting is that their banter occasionally hints at a shared history; they clearly knew each other as kids. Fans have theorized they were actually friends at one point, which would track given that both ended up in Team Rocket. It's also made people wonder if Yamato, like Musashi, had a parent involved with the organization—that would explain a lot about how they both got recruited.
There's a memorable Battle Frontier episode where Takeshi gets smitten with Yamato after she disguises herself as Nurse Joy. He catches on pretty quickly though—his deep knowledge of the Joy family tips him off that something's off about her.
