In-Depth Analysis
With a base stat total of 530, Aggron plays as a slow bruiser that trades speed for raw hitting power. Its standout stat is Defense at 180, while Speed (50) is the clear soft spot — build sets that protect that weakness.
Its Steel, Rock typing leaves Aggron with 3 weaknesses against 8 resistances and 1 full immunity. Watch out for Fighting, Ground moves in particular — they land for 4× damage. On offense, its STAB moves threaten 6 types for super-effective damage.
A low catch rate of 45 makes Aggron a genuinely tough catch; bring strong balls and status moves. It levels on the Slow experience curve. Defeating it grants Defense +3 EVs, which is worth remembering when EV-training your own team.
