Aggron is able to threaten most of the tier with its high base power STAB moves. Aqua Tail provides coverage for bulky Ground-types like Palossand and Sandaconda. Earthquake allows Aggron to OHKO opposing Aggron, in addition to evading chip from Rocky Helmet users such as Sandaconda. Superpower is an option to hit Ferroseed super effectively and deal more damage to Regirock, but it usually isn't worth it. Choice Band Aggron appreciates pivots such as Whimsicott and Uxie that lure passive Pokemon such as Aromatisse and Audino for it to take advantage of. Pokemon like Basculin and Archeops can exploit Aggron's typing to gain momentum, so it appreciates support from bulky Pokemon such as Jellicent and Sandaconda. Sandaconda and Uxie also spread paralysis for Aggron.

Aggron is great at sponging attacks from Ribombee, Mesprit, and other special attackers with limited coverage. Even without investment, its STAB moves hit hard and keep it from being passive. Protect makes playing around Choice-locked Pokemon like Gallade and Mesprit, as well as Future Sight users such as Galarian Articuno when they are paired with Pokemon that can threaten Aggron directly, much easier. Toxic is useful to wear down bulky Pokemon like Palossand and Tangela. Roar can rack up chip damage, especially when paired with Spikes from Froslass or Qwilfish. Roar also pairs amazingly with Future Sight users like Galarian Articuno to wallbreak. Wish Aromatisse and Healing Wish Mesprit are great tools to keep Aggron healthy, with the former also absorbing Knock Off for Aggron. Other Knock Off absorbers like Weezing and Qwilfish are also useful against Pokemon such as Sawk and Ferroseed. Pokemon like Charizard and Claydol, which can remove Spikes, assist Aggron in not getting worn down too quickly.
