"Manga material" is more practical. It has no built-in subjectivity. You yourself called it that in previous answers. Maybe this one should ignore what you say like they do with "fillers
Let's go. Let's give you what you want.
In the original manga, Trunks warns the warriors about Androids #19 and #20, but later this is contradicted when Trunks reveals that the androids that destroyed his future are, in fact, Androids #17 and #18. Notice how the contradiction is later, not earlier. He simply rewrites what came before.
Now let's bring this example to the Garlic Jr. arc:
Yes, it contradicts the claim of five years of peace without major threats and Kuririn doesn't know Gohan until he meets him at Kame House, right?
It turns out that the inclusion of the Garlic Jr. arc simply overwrites this fact because it is a later inclusion, as well as the revelation of the androids from the future being #17 and #18. There is no ignoring a later inclusion by a previous one. It's the opposite. As a rule, what comes next is what counts.
Come on, I can cite countless examples where previously unreleased content from the anime blends well with the adapted content from the manga, as well as replacing it.
• The adventures of Pilaf's gang while Goku and Bulma search for the Dragon Balls;
• Yamcha's training for the 21st tournament;
• Goku's adventures before the 22nd tournament, including his first encounter with Tenshinhan;
• Goku and Yajirobe's search for the Super Sacred Water;
• Goku and Chichi's pre-wedding adventure;
• Gohan's training to survive in the desert;
• Goku's adventures on the snake way and hell;
• Lunch chasing Tenshinhan to Karin's Tower;
• The gang watching the battle of the Saiyans on TV and later the scene from the manga being adapted to the anime to fit in with this segment;
• Bulma and Ginyu switching bodies doesn't contradict anything either;
• Vegeta going into space to look for Goku, going through the Garlic Jr arc and returning on the day of Freeza's arrival on Earth;
• Vegeta's training to become a Super Saiyan, as well as his relationship with Bulma;
• Mr. Satan's disciples;
• The adventures of the Great Saiyaman;
• The moments of peace after the Boo arc;
There are many segments, actually. Contradictions exist in any work, I just think it's stupid to take away the relevance of all "filler" content or to diminish an entire arc as if it were not coherent with the series in most cases.
This argument that "filler must be completely ignored for things to make sense", as you said in your first reply, falls once again into subjectivity. Do you have to ignore all fillers? Do you have to ignore just some? Which ones? Who decides that? It's either all or nothing, my friend.
You say no, but you establish a hierarchy between content adapted from the manga and original content/filler. They should be given equal weight.
I hope you took your hands off your eyes so you can read and interpret what I said. I feel like I'm talking to walls instead of a real person.
