You deleted a page I was creating titled "Possible Viewing Order" in which I was attempting to piece together a narrative for the manga/anime/remake and movies so that they make sense. I was still in the editing process but the page was deleted. Can you restore it until I get the chance to recover the info for myself at least?
There is a question the The Brief Return of Dr. Slump (mangá) is part of the Main Story (Official Story) of Akira Toriyama or not part of the Main Story (Official Story) of Akira Toriyama (Is considered a Side-Story)?
Since Akira Toriyama didn't do the stories, nor artwork for the series, it's safe to say that it isn't a part of the main story of Dr. Slump. Since some characters were redesigned, Brief Return can be considered an alternate universe of sorts. This can also explain why Dr. Mashirito is still alive despite being killed off. Toriyama-sensei only played a supervisor role in the project.
Other anime I watched partially are Full Metal Alchemist, Lupin the Third, Doraemon, Dragonball (Z-Super too), Naruto, Seven Deadly Sins, Demon Slayer, Jojo's Bizarre Adventure.. That's all at the top of my head.
I love western animation more probably. Stuff like Spongebob, The Fairly Odd Parents, The Amazing World of Gumball, The Simpsons, Looney Toons, etc.
I don't have much time to watch these things anymore, but whenever I get time I may consider it.
