What Pokemon can break rock on prism?

It seems like you're asking about the "Prism" mechanic in Pokemon games, but it's not a real concept. Could you clarify what you mean by "break rock on prism"?

Here's why your question is a bit confusing:

* Prisms: The term "prism" is associated with specific events or items in Pokemon games. For example, there are Prism Towers or Prism Scales.

* Breaking Rocks: Typically, Pokemon break rocks by using moves like "Rock Smash". This is a move that you learn from a specific TM.

Do you mean:

* Which Pokemon can use "Rock Smash" to break rocks?

* Is there a specific event or item related to prisms that involves breaking rocks?

Please give me more information so I can help you!
