Kizaru speed and ap is more than enough to take on at least one of them. Dante can't neg intangiblity due to the fact Sabo was still able to move around once he turned into fire during the fight against Fujitora. They also don't have any heat or cold resistance on the level of that they can produce. The admirals scale to him or even above him( probably above Fujitora, I'd say that he is the weakest even tho we haven't seen the fourth).
I don't wanna do the admirals because you already know but here is my opinion on the battleĪkainu > Zenon(no spatial magic) > The rest of the admiralsĭante does not have better gravity control than Fujitora who can bring down meteors ( a meteor at time and it takes him a lot of time) and pick up an entire country' rubble from the floor( country sized ease prove it). Vanica can curse the opponents such as slower movements,death curse,Stronger but weaker body Vanica also has curse magic where it be Good or bad. This is really powerful because she can manipulate the blood in her opponents body. Vanica has blood magic that can manipulate blood.
Zenon also has spatial magic,He can stop attacks by placing them in a box(not known if it only works on mana attacks) Zenon has this move where he can makes a box in the battle field and anything that trys to attack him will be gone It can be defensive and offensive like destroying aokiji ice but probably would fail against akainu. My theory is that dante may be planterary level if he can change the gravity of a planet making everything crumble to pieces and the admirals would have a hard time(except fujitora but he isn't in here) He has MTFL reaction/speed from dodging yami and asta's attacks. I will try to explain why the DT will winĭante has singularity which destroys everything around it(Logia effect will be useless) He also can't die(from them) because of his body magic which regenerates like crazy.
