Super Sommers and Killingham are the perfect secondary villains for this arc
Having them briefly clash with Zoro and Sanji earlier made no sense. Served no purpose other than to downplay their threat level, which is high stakes considering Imu is here too. Z/S damaged going into the battle is probably used to get them in a state of haki bloom soon, they're due for new power ups
That MMA Zaza is probably as big as Niddhog Loki sheesh. Hot take but I believe he can normally summon that outside Omen too. Massive Killingham upscale
