youre welcome <<
you only have those 2-3 worlds left?
youre about 3/4 done .-.
after you beat hallow bastion, pride lands, and atlantica you get the world that never was.
you have to clear that world to get to the final battle. (its actually a straight forward world .-. just kill everything in your way, beat a few bosses, find everyone, unlock some secrets, etc.....)
oh and your forms will coem in very handy during this so MAKE SURE to have as much in your drive gauge as possible.
also unlock final as soon as possible
the underworld tournament is the fastest way.
also have you gotten space paranoids?
its in hallow bastion.
you go in, beat the MCP, take back control of Hallow bastion, etc..... its one of the worlds that you need to beat
