Battle notes
- Aron's Steel / Rock typing is best attacked with Fighting (4x), Ground (4x), Water (2x). Start with those attacking types when choosing moves or counter Pokémon.
- Avoid relying on common Poison, Normal, Flying, Ice attacks unless they have unusually high power or a secondary purpose, because Aron resists or ignores those matchups.
- This guide uses the modern Gen 6+ type chart only. Abilities, held items, Terastallization, weather, fields, and special move rules can still change real battle outcomes.
