TBD

This is the replacement for "Metal Crusher", though the situations it plays in are probably closer to where "Undyne" / "Danger Mystery" / "Run!" / "NGAHHHH!!!" would play for Undyne in the original game.

I always found the Altertale set of swaps to be interesting, and am disappointed at how poorly they're executed in the original AU.

Swaps:
Undyne with Mettaton!

Leitmotifs:
Undyne (part 1, Part 2)
Uwa!!
