So, this is interesting. Remember the Batman embargo of the mid 2000s, where major Batman characters couldn't appear in more than one show in major roles (such as how Batman didn't appear in Teen Titans, Robin didn't show up on The Batman until season 4 [which was after Teen Titans finished], and the Joker didn't appear for the remainder of the DCAU? I think a similar thing might be the case when it comes to Disney Ducks, as evidenced with DuckTales 2017 and Legend Of The Three Caballeros. Think like this. Donald is a main character in the former, but he doesn't appear in every episode. In the latter, he's THE main character. Scrooge, the main character of DuckTales, only makes a cameo in one episode of the latter. Panchito and Jose are also leading characters in Legend Of The Three Caballeros, but their appearances on DuckTales were after the show ended (they didn't appear until season 2, which came out months after the former ended). Likewise, Daisy only started appearing on DuckTales in season 3, after LOTTC ended. Another factor is that while much of the main cast of DuckTales is based on established characters with originals thrown in, most of LOTTC's cast is composed of original characters (like Xandra, Baron Von Sheldgoose, and Lord Feldrake), with neither of these show specific characters appearing or even being mentioned in the other. One final thing is with how, while DuckTales has Huey, Dewey, and Louie, LOTTC has April, May, and June, whose only major appearance is in that series and nothing else. It could be because both shows were developed by different departments of Disney (Disney Television Animation for DuckTales, and Disney Interactive for LOTTC) despite being in production at more or less the same time (DuckTales was announced in February 2015 and came out August 2017, a production of 2 and a half years. LOTTC is most likely the same since it came out June 2018). Still, what do you think? Is there some kind of Disney Duck Embargo?
