brooo, what the fuck was that?
it's very nice that sanji mastered his germa abilities so fast, and he said that he was training his armament haki off-screen, so now he can combine all of it in the same time, but it looks like it consumes a lot of energy.
looks like sanji doesn't infuse the flames with armament, but instead he infuse his leg which makes it capable of handling greater heat to produce hotter flames, i never thought sanji can overheat, which means that he can raise the temperature indefinitely as long as he can still handle it, basically unlimited potential.
and his invisibility is in fact extreme speed.
overall a badass set of skills.
and it looks like queen can execute all of germa's abilities even the ones that's not raid suit specific, i'm not sure though, but it looks like he can even replicate sanji's flames with his "bridal grabber" attack in chapter 1023.
