It is
Intangibility that helped him to overcome Fujitora's gravity. He was lucky to be a logia, otherwise, that attack would have finished him
You mean that hiken that shattered the coloseum bottom floor? The fire power displayed is vastly above anything regular Sabo showed the capacity to accomplish.
What a joke! He has:
1- Long range attacks(when he was a close range fighter)
2- Intangibility(that saved his ass versus Fujitora)
3- Huge fire power(town level destructive capacity). He even set the entire city on fire during his fight versus Fujitora
4- Great manoeuvrability(fire logia gives some sort of levitation and cross distances faster like we've again seen against Fujitora)
Sure this Sabo isn't different at all from his pre-mera version, just like how zoan Kaku was no different from normal Kaku after eating the fruit Lol
You spend your time overwanking Doffy by puting him above characters beyond his reach at every occasion you can, hence i called you a wanker
I don't need more feats to know Sabo is stronger than Doffy just like i don't need Rokugyou to show his feats before knowing he is stronger than him
Other than Hiken, nope.
He was actually lucky to be facing an attack of a nature that can't be imbued with Haki. Note I said ¨a proficient Haki user like Doflamingo¨, as in, someone whose arsenal revolves around either Haki or an ability that is often used in conjunction with Haki. If it was something like a slash from Mihawk, or a punch from Akainu or an Overheat from Doflamingo and Sabo attempted to just tank it, he would have been killed or at the very least severely injured by the move.
When did I try to undermine the value of Hiken? I said other than Hiken. And even Luffy could have done something like that with a Gear Third attack. It'd be foolish to think Sabo, who was undoubtedly stronger than Luffy prior to eating the fruit couldn't have done without the Mera's powers.
Like I said, Hiken is a valuable addition, but that's pretty much the only valuable addition. Intangibility would just be circumvented by people who actually fight with attacks imbued with Haki. Also, you have no proof that Sabo couldn't physically withstand the Graviton attack. It crushed buildings, big whoop. Luffy was doing the same thing pre-skip. His maneuverability isn't any faster, it's just as good as it was before.
Kaku's case is entirely different. A Zoan fruit automatically boosts your physical stats when transformed, so every person would get stronger when they eat a Zoan if it isn't something like a turtle or a stickbug. Logias work differently.
