Registeel can only be obtained once from the Pro Path. It can then be obtainable randomly from the Endless Path.
Hatching a Registeel egg will not count towards your Shiny Chain. You can obtain a Shiny Registeel Egg by completing 1000 levels in the Endless path, though you have an equal chance of obtaining a Shiny Regirock or Regice Egg as well.
|EHP:||EXP to level 100:|
Registeel does NOT evolve.
