Fair enough, I'll write this base off as a staging area but the main base will be inaccessible by teleportation or any cheap means, I'm not having you protagonist break a plan I've had in motion since the pouchers were first introduced. 
Right now, this is how I see the big Poucher base beat going and everyone final boss within it: Maribella vs Shinranui, Liam vs Nigel, Chuck vs Alexa/Alexander. 
I've got big plans ready, Epically for Nigel and Liam. Oh that remind me [@Alisdragon911]. Is there a named poucher you would like to fight as your final boss of the poucher base?
