What is every example of a Pokemon learning an HM through level up?

Question

I know Seaking is the only one with Waterfall.

Comments

Which generation is this for?

---

all of them

Answer 1

Goldeen gets Waterfall by level-up.
Seaking gets Waterfall by level-up.
Salamence gets Fly by level-up.
Rayquaza gets Fly by level-up.

These are the only four. Only two HMs, as of Generation 6 (the last games HMs appeared in), have been legally obtainable through natural levelling means.
