I disagree only with this point. For some reason people think that Admirals should fight like Kaido and Whitbeard using nuclear sized blasts, when they have their own unique powers and abilities. Kizaru's shtick is his speed, and showd plenty of it. And Goofy isn't the easiest opponent out there, so cut some slack for Kizaru.
Law has average young dude voice
Kizaru looks underwhelming exactly because he fought Goofy who was out of his league
His accelerated kick, which knocked back G4 Snakeman, was undermined by Goofy being more hurt by Vegapunk's barriers
His lasers, attacks which are supposedly unblockable, got eaten by his G5 going toon
He kept running away from the battle and then got knocked out by an attack that is mid-tier in Goofy's arsenal at best
Actually, his lasers even got negged by Sanji's power of love.
Compare that to Nasjuro who managed to look more lethal and destructive with Shodai Kitetsu alone
He did create some tension when luffy was sweating saying someone strong was there . It was hype !
Okay, cliffhanger tension then. But it all went downhill from there when Goofy undermined his status and when he couldn't even KO Sentomaru for more than a chapter
