Zaraki is a lot stronger than Regal. While Regal has Lazerman and Nebula Grey’s power he can’t take on Zaraki. Zaraki’s aura’s too much for Regal. Regal better stay down. Zaraki wins.
Zaraki has a giant aura that could easily beat Ivy. Ivy may have a whip, but that can’t help her too much in this world. Ivy is also a pretty cheap character who has no hope left. Zaraki wins.
Carmilla has some powers, but not nearly enough to take on Zaraki. Zaraki is arguably the strongest Bleach character ever! Carmilla is just a mortal with no hope of surviving. It’s too late for her. Zaraki wins.
This is a tribute to Salt. Salt is like James Bond but with much fewer weapons and less physical strength. While she knows some hand to hand combat it’s not enough to get a hit on Zaraki. Zaraki wins.
Zaraki is so much stronger than Mai his aura would blow her away with no effort. While she has her harpie ladies, they couldn’t get one hit on Zaraki. Zaraki is just too tough for her. Zaraki wins.
This is a tribute to the second James Bond film. James Bond is okay, but since he could hardly handle a normal human then he definitely can’t handle Zaraki. Zaraki’s sword skills are far superior. Zaraki wins.
Zaraki’s back and he’s challenged the former man of steel. Because if Superman’s steel…Zaraki’s Antimantium. Most swords can’t even hurt Zaraki. He even survived dozens of swords hitting him without caring. Zaraki wins.
Now this is a real fight. They are both top class Soul Reapers. Either way regardless of who wins these 2 are definately the top 2 strongest Soul Reapers. I think that Zaraki would win in a very close fight. While Byakuya does have bankai while Zaraki doesn’t. Zaraki could still take him because of his sheer strength and spiritual pressure. It was been known to outclass even other Captains. He even took on 2 teaming up. But Byakuya also has skillz. But now Byakuya has surpassed Zaraki. Byakuya wins.
