Original Gowther vs Zeldris
Tough to say since we don't know anything about how strong OG Gowther was and what his combat capabilities were like. We can only rely on statements. He looked confident in fighting Zeldris, even though he said that he would waste a lot of magic doing so and OG Gowther doesn't strike me as some type of fool who would overestimate himself or underestimate his opponents. That being said, OG Gowther probably can bypass The Ruler with his magic, he already did it by modifying the DK's memories, someone far above Zel. Yes, it was through a life-risking technique, but he not only affected the DK, he was able to affect everybody on the Holy War. Zel has an incomplete version of that magic, so him being affected by high-level spells from OG Gowther is not impossible. I'm gonna say Zeldris. I don't know the difficulty tho, maybe high.

Original Gowther vs The One
- Leading towards OG Gowther.
- I'm assuming it's King with his fully sprout wings. In that case, he wins.
- Sariel wins.
- Tarmiel wins.
- Ludo wins.
- Most likely Eli if she is off-character and bloodlusted. Even tho, I have my doubts.
- Mael wins.
- Most likely Chandler.
- Most likely Cusack.
- I literally don't have any idea about the Sariel and Tarmiel ones.
- Most likely Ludo.
- Eli most likely has more raw magic power than him, however OG Gowther's magic is way more lethal, to the point that if he lands one hit I see him taking the victory. Eli doesn't seem to have much battle experience, meanwhile OG Gowther seems full of it. I'd say OG Gowther more times than not. I could be wrong tho, since I'm not too sure about it.
- Mael wins.
- The One wins.
All these matchups with OG Gowther are tricky. In raw power he's definitely below the likes of Mael, Ludo, Eli (probably), The One, etc. The thing here is that his magic is so haxed that he can potentially end the fight if he caughts them.

Cusack vs Chandler
- Merlin probably wins. She can do the same trick that she did against Chandler and Cusack and teleport far away to evade possible Escanor attacks. If she can do that, she wins.
- Merlin also has a chance, but if Mel uses his OG Magic it's over for her.
- Merlin wins probably.
- Hard to say, they look like equals to me, but I'm gonna say Chandler since he has more versatility than Cusack. Extreme difficulty.
All these Merlin with preparation fights are even more tricky since you could take into account infinite possibilities.
