Pokemon GO: Great moves and Pokemon to take on Aggron

Aggron is resilient, but nowhere near invincible in battle if trainers play to type advantage (Image via The Pokemon Company).

Aggron's Steel/Rock-typing, along with its defensive capabilities, can make it a tough target to take out in a protracted fight. However, it retains three elemental weaknesses, two of which are doubly effective and deal severe super effective damage to it.

For Pokemon GO trainers hoping to topple Aggron in either PvE or PvP battles, opting for a Fighting-type or Ground-type Pokemon will go a long way. At the very least, Fighting-type or Ground-type moves should be used if matching Pokemon aren't available to use them.

How to defeat Aggron

Aggron has a few weaknesses (image via Niantic)

In total, Aggron is weak to Fighting, Water, and Ground-type moves in Pokemon and Pokemon GO. However, Fighting and Ground-type moves are super effective against both of Aggron's types, dealing double the super-effective damage compared to the normal one inflicted by water attacks.

If players are able to use Fighting and Ground-type Pokemon in Pokemon GO and match the moves, they'll also be able to obtain a Same Type Attack Bonus, magnifying the damage on Aggron even more.
