We need filler on the first four Hokage.
- Hashirama: we need more details on his reign as Hokage, especially after his victory over Madara. What was his relationship with the Uchiha like and how the Uchiha reacted to Madaras death. We also need some back story on Mito, how did Hashirama meet her, how she became host to Kurama and more info on the Uzumaki clan and the land of whirlpools. What would also be nice to see is the coming together of all the clans of Konoha, seeing Sasuke Sarutobi and other clan ancestors from the Hyuuga, the Shimura clan etc. And finally the #1 question that we all want to know is how the heck did Hashirama die?
- Tobirama: I want to see his establishment of Konoha, how he created the Uchiha police force, how the Uchiha felt about Tobirama and such. Also seeing how Tobirama created some of his jutsu would be nice, as well as Team Tobirama and young Hiruzen. Most importantly his death needs to be fully explained and his beef with the Gold and Silver bros.
- Hiruzen: We all want to see what he was capable of in his prime, how he faired as Hokage at such a young age. Seeing the young Sannin and what kind of team they were would be great too.
- Minato: I mainly want to see him growing up, how deep was his relationship with Jiraya. Minato signing the contract with the toads, how he Buntas respect, and of course his Sage training. I also want to know how he learned FTG as well as seeing him develop the Rasengan.
