It's due to speedblitz. Fodder Bronze Saints doesn't have much speed feats. Also I wonder: Is it Ikki when he just had his Bronze Cloth or EoS Ikki with limited to Bronze Cloth? There's a huge difference between the two. Bronze cloth or not, EoS Ikki is FTL. He can literally punch each and every Shinigami to space in the matter of seconds.
Unlike most comic book characters, Ikki has spiritual awareness, so seeing them will be no problem. If it's to the death, there's no way he's losing. Also, there are 3 versions of his Bronze Cloth, which one is being used here?
