If a Rhydon with the Rock Head ability evolves, will it's ability change to Solid Rock? (or is it a 50/50 chance of getting Lightning rod
(I'm guessing that a Rhydon with Lightning rod wouldn't change it's ability)
If Rhydon has the Rock Head ability, it will always gain Solid Rock. If it has Lightning Rod, it will have Lightning Rod when it evolves.
