Blastoise never learns Crunch. Blastoise does not learn Crunch, but it does learn Bite. This is when it is a Wartortle (or Squirtle) and is on level 16. If you have a Blastoise on level 16 (which is not really possible), it will learn Crunch.
Luxio will learn Crunch at level 33 but you have to stop evolution at level 30 though. You can always evolve it to Luxray and it will learn at level 35 instead.
