Literally every single one. They say, gin ichimaru's bankai with buto = mach 1000, and ichigo dodged it, so ichigo's mach 600, but then with hollowification, ichigo gets 5x so he's actually sub-relativistic with it, and gin is also sub relativistic now. Then for the war arc, they're like, ok so it's ok to say they're relative to these other characters, right, and then use something about cloud to cloud lightning to say that their attacks are lightning speed for some reason, and then say they have mhs+ combat speed, and they get speedblitzed by ichigo, and then calcstacking that speedblitz to relativistic.
