So thanks to
NessAtc.
a few minutes ago, we noticed something quite interesting… Rex's spirit fight is on a different stage now.
Not only spirit fights can get their mii fighters updated with costumes, but also stages can be changed as well in spirit fights. Nothing is impossible in this game, if something new exists, they are willing to update anything in the game.
Some of us already believed in it, but it's great to actually see it be done, for anyone who thinks they would limit themselves to updating stuff if we get new fighters or miis, lol.
Pretty sure having a fighter Isaac and a GS stage would be no problem to have changed from whatever we currently have with Isaac's spirit fight, for example.
