i don't think for now there will be a big fight until Quinn's kids are born but here's the thing according to mundus the marpo cruise have the power to change the balance whole universe and the power they have is frightening for even the celestials and it's not stagnant it's growing by time so what if Jim has the whole universe under his control coz marpo cruise ran along many solar systems so if Quinn is going against Jim if he doesn't find how to reverse Malik's ability then he is going against the entire universe and if need be instead of fighting against celestials Quinn would need their help. Quinn is growing his army with beasts but even a four spike dalki are capable of taking down demon teir beasts and Jim has his full army that is not released plus they have abilities and five spike dalkis are just captains of cruise. if Jim can supply 8 spike dalki blood to leaders then he knows how to counter them so he would have dalkis with more than 8 spikes so in some case it may be helpful to use infected beasts but in large scale I think it's not enough the weapons that he has now is only one, his guns but he would need more of godslayer weapons to fight an army fighting a great mind like Jim maybe even tougher than fighting immortui or mundus
