First, watch the original Dragon Ball. After that, continue with Dragon Ball Z. Finish with Dragon Ball GT. Make sure to follow this order for a seamless viewing experience. Also, note that there are some spin-offs and movies that you can watch separately if you want to explore more of the Dragon Ball universe.
The best way is to start from the beginning. Dragon Ball has a clear chronological order, and reading it in that sequence gives you the full experience of the story's evolution and all the exciting moments as they were meant to be enjoyed.
You can try some fanfiction websites like FanFiction.net or Archive of Our Own (AO3). They often have a wide variety of Dragon Ball fanfiction available for reading, but not for direct 'watching' in the traditional sense. However, you might be able to find some fan - made animations or video adaptations of the fanfiction on video - sharing platforms like YouTube, though this might be less common and subject to the platform's terms and conditions.
As mentioned before, FanFiction.net and AO3 are good places to start. Check for any video links in the comments section or if the author has mentioned any related video adaptations on their profile. Another way is to search on social media platforms like Twitter. Use relevant hashtags such as #DragonBallFanfiction and #WatchDragonBallFanfiction. Fans might share their own video creations or links to existing ones there.
In a sense, it could also be normal if we consider that Goku is always open to new experiences. He has been exposed to different planets, cultures, and types of power in his own story. So, watching a fan - created version of his story, although different, could just be another new thing for him to experience, even if it seems a bit strange at first.
You can start by looking on video - sharing platforms like YouTube. There are often channels dedicated to Dragon Ball Abridged fanfic. Just search for 'Dragon Ball Abridged' and you'll likely find a bunch of them. Another option is to check out fan - made websites or forums related to Dragon Ball. Sometimes, fans share links to their favorite abridged fanfics there.
Goku's understanding of different universes and races could be deepened in fanfiction. Since Dragon Ball Super introduced the multiverse concept, fanfiction could explore how Goku interacts with and learns from beings from other universes, making him more worldly and less naive in some ways.
