Weaknesses: Weak against Water type attacks, very weak against Fighting, and Ground type attacks | Weak against Fire, still weak against Fighting, and Ground type attacks but not as much. Aggron can only access their Mega Evolutionary stage through physical possession of a specific Mega Stone type that is uniquely attuned to that species and resonating the Stone with an accompanying Mega Ring (or similar device containing a Key Stone), which can only be constructed by artificial means: this excludes most wild specimens from harnessing the innate evolutionary potential, leaving only individuals in captivity as probable candidates for Mega Evolution. Mega Evolution is not a permanent transformation; specimens immediately revert back to their "base" forms once combat has been successfully concluded.
Notable Attacks/Techniques:
Abilities
- Sturdy: Aggron's primary special ability. Aggron with this particular ability simply have even higher compositional durability than other members of the species that lack this attribute.
- Rock Head: Aggron's secondary special ability. Most Aggron have their rocky and metallic hybrid composition further enhanced with shock-absorbent structures, preventing any possibility of self-trauma from recoil of their more reckless physical attacks.
- Heavy Metal: Aggron's hidden (tertiary) special ability. A select few Aggron are composed of an unusually heavy metal alloy, doubling their weight (720 kilograms) compared to the average (360 kg).
- Filter: Mega Aggron's sole special ability. As a result of the Mega Evolution, these Aggron have developed an anomalous characteristic within their metallic composition which automatically reduces the incoming energy output of techniques and abilities classified as "super effective" against Aggron physiology (such as fire and extreme heat in general) to much more tolerable levels; in optimum circumstances (i.e. against creatures or beings of comparable power to Mega Aggron), the output decrease is 25%.
Moves
- Tackle: Aggron performs a full-body tackle.
- Harden: Aggron stiffens its body structure to augment its physical defenses.
- Mud-Slap: Aggron hurls mud at the opponent's face with the purpose of blinding the enemy, as well as inflicting damage.
- Headbutt: Aggron executes a headbutt.
- Metal Claw: Aggron tears at the opponent with its steel claws.
- Iron Defense: Aggron further reinforces its metallic-like composition, radically augmenting its physical defenses.
- Roar: Aggron makes a savage roar, alarming other Pokémon and other organisms, often to the degree of fleeing the battlefield out of fear.
- Take Down: Aggron performs a reckless, full-body charging tackle that also slightly harms itself in the collision.
- Iron Head: Aggron uses its metallic head to its advantage and executes a powerful headbutt.
- Protect: Aggron uses its self-preservational instincts to expertly predict incoming attacks and defend itself accordingly.
- Metal Sound: Aggron emits a horrible noise like scraping metal which operates on a particular frequency, causing the direct-energy defense(s) of any organism in audible range to be reduced.
- Iron Tail: Aggron slams the opponent with its metallic tail.
- Autotomize: Aggron voluntarily sheds portions of its metallic frame, removing unnecessary weight to greatly increase speed.
- Heavy Slam: Aggron uses its great mass to slam into the opponent. Delivers damage depending on the weight of the target, causing as much as 3 times the harm to organisms weighing 20% or less of Aggron's weight compared to organisms weighing 50% or more of Aggron's weight as an example.
- Double-Edge: Aggron performs a reckless, full-body charging tackle that also slightly harms itself in the collision.
- Metal Burst: Aggron deliberately tanks the incoming attack of the opponent, before retaliating with either an explosive mêlée strike (if the initial attack withstood was physical in nature) or unleashing a linear 'blast' of metallic shrapnel (if the endured attack was elemental/direct-energy in properties), taking advantage of the stored energy directed at Aggron to augment the burst to 1.5 times the power of the opponent's initial attack.
- Body Slam: The user slams the opponent with its body, dealing heavy damage and potentially paralyzing them
- Curse: The user curses the opponent, lowering the user's speed and boosting its attack and defense
- Dragon Rush: The user charges at the opponent whilst covered in dragonic energy, dealing heavy damage and exhibiting overwhelming menace, potentially causing the opponent to flinch

- Head Smash: The user lands an extremely powerful attack with its head, damaging itself in the proces
- Reversal: The user deals loads of damage based on how much HP it has lost, dealing more when heavily damaged
