I disagree with the thread in general, though specifically focusing on the Toshiro stuff….people keep saying he has an elemental advantage over her which isn’t true. He can freeze her water and she could melt his ice. The fact that they both can mutually affect each others elements that are powered by their spiritual energy implies some form of relativity when it comes to AP. The best evidence is him stopping her Cascada, which most forms of media seems to show as her strongest attack. Her ‘Desgarron’, ‘Lanza’, ‘Respira’ etc equivalent.
Should also be noted that he was only ever getting overwhelmed by her before the ice clone was ‘killed’, during his observation period. Once he got a grasp on the speed and power of her Res, she never overwhelmed him again with her speed or AP. When the ice clone was ‘killed’, she even dodged his physical sword strike despite her having Hierro passively active at all times, implying his striking strength could cut through her Hierro. Which makes sense if the general AP of his Zan ability = the general AP of her abilities
Anything before the ice clone can’t really be used for scaling as both Base Halibel and Base/Bankai Toshiro were holding back. Even afterwards, Toshiro noted he was waiting for the ice petals to melt down a bit before using Tenso Jurin as he didn’t want to kill his allies by mistake.
Bankai Toshiro and Res Halibel should scale, and the stipulation that he was only keeping up due to an elemental advantage should be removed from his profile as they both cancelled out.
He should have ‘higher’ with Tenso Jurin and HH though. We’ve only seen TJ twice, but based on its first use against Gin, it isn’t just a single shot attack, Toshiro can maintain it for an unknown amount of time and his attacks would most likely be buffed for that duration. For HH, we know it’s such a big increase that Halibel couldn’t melt it despite being able to melt everything else. And both TJ and HH impressing Starrk enough for him to go Res and try to force Kyoraku to display a power on that level or higher implies it’s a big jump.
Last point disagreeing with the FKT Toshiro downgrade….I don’t remember the exact context cuz it’s been a few years since I read this encounter, but CFYOW Halibel compared the early version of Hikone that got reverse jumped in Hueco Mundo to FKT Toshiro, though I don’t exactly remember who Hikone damaged, what forms they were in etc but that version of Hikone and all of them pretty much scale to High 6-A
