Leopards suck. Lions are the fiercest, cheetahs are the fastest, tigers are the biggest. Leopards and cougars are just leftover cats. Cougars are the worst, though.
Lucchi and Jyabura have some sort of rivalry, I think everyone agrees.
To have an equal rivalry such as theirs, both parties must be equal in strength, I believe.
Lucchi's douriki is almost 2000 higher than Jyabura's… that is a fact.
If that's the case, why does Lucchi still consider Jyabura a rival of his, even though his douriki without zoan transformation is so much higher? Lucchi even was beginning to morph into his leopard form if not for CP9 breaking their fight up. It puzzles me greatly why Lucchi would acknowledge someone with strength so much below his to such a great extent.
My conclusion is that Jyabura's devil fruit power far overshadows Lucchi's, hence after transformation, both have a very close douriki level. Say, since Lucchi's is a leopard, a semi-strong feline, Jyabura's would be a wolf, the strongest (?) canine around. Is that a plausible idea?
Some people mentioned that since Lucchi is a leopard, Jyabura can't be a wolf, since it's too far off in terms of power from Lucchi. I believe the opposite. Discuss, and opinion-barrage this thread please.
I think you're putting too much into the "douriki" thing. It didn't measure overall, just strength, if anything. Or "athletics," as stephen had Jabura and Lucci put it. It seems like you see it as DBZ power levels, where the higher number is just better in everything there is to be better in. Three things:
Speed. As Google research showed, big cats are bigger than wild dogs. Maybe Jabura has more speed?
Skill. Hitting power doesn't matter as much as some would think if the other fighter knows what he's doing.
Time. Jabura says that they've gotten stronger. Maybe his douriki was formerly equal to Lucci's? And it's not like they'd call in their rivalry after one just turns up stronger. Outdoing the other is what makes rivalries anyway.
Oh, and Lucci probably transformed to match him because if they fought, even if Jabura's DF powers couldn't match Lucci in strength, he'd probably be more ferocious. Ferocity is part of the reason that a dog sized wolverine can beat a 500 pound moose.
