>>48294241Me and my friend nuzlock every game on our first playthroughs of them. The only thing I had an issue with on USUM was totem Togedemaru since I had literally 0 ground type moves.
Both of us had zero problems with ultra necrozma, I'm honestly surprised to hear people even have a clause for it.
I will back you up though and say red isn't that hard, he only looks scary cause his pokemon are high level.
