Here is a meme where you can put your least to most favorite Yu-Gi-Oh! Protagonist from each series. feel free to use it and remember to credit me.
I haven't seen GX and 5DS since I was a kid and I only watched two episodes of Zexal and Arc-V and I just read the manga version of Arc-V. The only protagonists I know are Yugi, Yami, and Yusaku. Not to mention two of my YGO OCs for my upcoming fanfic story, Yu-Gi-Oh! Starlight Heroes, Junko/Juno Yusa and Starlight.
