- Escanor will lose the Sun grace and it will go to Mael, showcasing what power had the strongest of the Four AA back then. I also want to see him get some interactions and tag team with his brother Ludo. Ludo will probably die protecting him.
- Ban will revive Elaine giving her infinite life.
- 5C Mel vs Stigma. This will serve to showcase Mel's powers after absorbing the 5C and also to see some really good alliance teamwork. After some battle, Emo Mel will return and manifest himself in the mind of 5C Mel. The Emotions and the "Dark" side of Mel will have an inner struggle that will weaken 5C Mel a little bit, only to be purified at the end by Eli with all the powers of the Alliance combined.
- The dark side and the emotions side of Mel will probably merge together, like some Naruto hugging his dark side thing. Ban's statement already foreshadowed that Mel is going to be unstoppable once he returns to his body. That's what I think it will happen. The power of Mel's emotions (who was enough to clash with the DK) + the power of his darkness (dark side) + his OG Magic.
- At the final day of the war, the seal will finally be broken and the DK is going to appear (the SD should also appear by that time). The origins of the conflicts between demons and goddesses will be explained by that time (probably some type of love between the DK and the SD that ended bad judging by how much importance romance has in the series). We will also get some backstory explaining Mel's OG power and why he's afraid of using it (my guess is that that power destroys everything around Mel, be it allies or enemies and the reason he's probably afraid of using it is because of that; maybe he also killed his mother with that).
- The new version of Mel is going to be a threat for the Gods, forcing them to retrieve all the commandments and graces to be at full power again.
- Meliodas vs Prime DK as one of the final battles of the war. The Ruler vs The Destroyer. I want it to be a cataclysmic battle just as Akira vs Takeshi in Nakaba's previous work (Kongou Banchou).
- Zeldris will end up being DK and Mael will probably end up being the one who leads the GC.
