>>44580514A lot of gen 8 mons could. I could see corviknight/dragapult flying around the haunted houses, eldegoss/flapple/appletun in the plains levels, orbeetle/toxtricity in the poison swamps, duraludon/stonjourner in the mountains, eiscue in ice levels, barraskewda/grapploct in the sea, and coalossal/centiskorch in castles. Hell even g max could work as each world's castle boss with kamek using magic to make them grow.
