Luffy is already fighting against them, but who amongst the crew will continue the fight? Sanji and Franky have fought against Saturn briefly in the past, but consider this to be from Chapter 1110 forward.

Something as simple as Nami using a lightning attack on one of them while escaping can be considered as her fighting against them.

Will be resolved when the arc ends or when the Five Elders are no longer an immediate threat to the crew.
