Not one you necessarily think will happen, but which would give the best hype for the Blackbeard Pirates:
Ideally I'd like a combination of the Red Haired Pirates and the Marines, basically a version of the God Valley fight where Rox comes out the victor:
Blackbeard vs Shanks - This fight would be a great way to hype up Blackbeard's combat abilities. People downplay this saying he's only strong against Devil Fruit users; however, Shanks is arguably the strongest haki user in the verse right now so Blackbeard defeating him would really hype him up better than any others.
Kuzan vs Kizaru - Kuzan gets some disrespect saying he's the third strongest admiral pre timeskip; however, if he beats Kizaru not only would this hype up Kuzan, but it would hype up Akainu as well as the man who was able to defeat him.
Shiryu vs Fujitora - Shiryu's ability ideally shouldn't work against Fujitora as Fujitora is a blind swordsman already. Therefore, this will hype up his swordsmanship showing he wouldn't need the Clear Clear fruit to be powerful, or it'll show his ability that he can hide from even Fujis CoO.
Lafitte vs Ryokugyu - We still don't know either's ability so not much to say.
Burgess vs Beckmann - Burgess needs a solid hype up fight if he's going to fight a serious opponent in the BB Pirates arc especially since he's likely to be given a powerful devil fruit.
Pizarro vs Lucky Roux
Van Augur vs Yasopp - Let's be honest this fight needs to take place for Usopps development
Devon vs Hongo - RHP officer and idk he doesn't give me any necessarily strong vibes to anyone else
San Juan vs Building Snake - I just like the theme of Battleship vs Builder
Vasco Shot vs Howling Gab - RHP Officer
Stronger and Doc Q Vs Bonk Punch and Monster - Human animal Combos
10th Captain vs Lime Juice
I think people go back and forth on Blackbeard defeating either some marines or the red haired pirate; and honestly, I think it'd be even more impactful if they defeated both. This will cause the marines to get even more desperate and if Blackbeard and Kuzan beats an emperor and an admiral then that sets up Luffy and a marine counterpart (Smoker or Coby depending on what camp you're in) Taking down Blackbeard and Kuzan themselves.
This is just my dream take, i think the BB Pirates have some of the best designs in OP and I like the stories of those we've met so far so I'm biased towards wanting them to be insanely powerful anyways.
