I cant imagine they will directly "defeat" big mom in the conventional sense like all the previous opponents. i doubt they will be be beating two yonkous, so the end game here is to escape once the have Sanji.

I definitely think Brook will be the secret weapon to surviving Big Mom. For all intents and purposes he is immortal, his soul persists as long as he has a body. Big Moms power does not appear to effect the body, and i dont think she can pull enough years from him to "kill" him. especially since his power gives him complete control of his own soul, leaving and returning to his body at will. so even if she can rip out his soul, he could just return to his body himself. after removing it she might be able to "hold on to" his soul or try to make a homy from it, but i figure he could just exit whatever object she puts him in as he can with his own body. on the other hand, her ability to physically interact with others souls could very well allow her to directly harm his soul making her the most dangerous person in the world to him.

Given that both their souls are described as having very powerful energy, and that he can greatly influence others souls. he might be crucial in dealing with the homies, particularly Zeus and Prometheus. i think by combining brooks power with the vivra card Nami has, they might even be able to turn the homies against Big Mom. That way once they neutralize the homies they will be able to escape.
