In theory an Automize set could work, but you need better coverage options-- double Tail coverage is completely walled by Water-types alone among other things. Dropping Hone Claws and going Automize+Iron Head+Earthquake+Fire/Ice Punch or something might be a better option, though that does still leave you walled by a fair few things.Here, I'm going to add my own crazy set to the pile.
Double Dance(?) Mega Aggron
Aggron@Aggronite
252 Attack/ 252 Speed
Jolly
-Hone Claws
-Autotomise
-Iron Tail*
-Aqua Tail* / Stone Edge
If you want to maximize special bulk while having max Attack investment, the ideal spreads are:
44 HP/212 SpDef/252 Atk if Careful
40 HP/216 SpDef/252 Atk if Adamant
Just saying.
Nehhhh not really. One Hone Claws barely brings it up to around 66% acc, if I recall correctly, which is still pretty atrocious. So on top of Automize, you'd need a minimum of 2 Hone Claws to make it even remotely reliable-- 3 turns of setup in which something can come in and Fire Blast you to death, sleep you, paralyze you to negate Automize, or phaze you out. Not a good idea.You could, in theory, transfer a Dynamicpunch Aggron all the way up from Gen 3 into XY. With one or more Hone Claws, it starts looking sort of reliable. It might just be stupid enough to work.
Elaborate
1: That's not the ideal EV spread for a specially defensive Aggron, or really, any kind of Aggron.My Shao Khan was Adamant, 252 Atk/128 Sp. Def./128 HP. I used Heavy Slam/Earthquake/Thunder Wave/Autotomize.
It's very mix-and-match.I wanted him to be offensive, not defensive. Actually, I tried to test both...and I wasn't really happy ;)
I did not used Autotomize with Heavy Slam, only with Earthquake. I know about the weight reduction/damage reduction relation.
Anyway, any viable build for Mega Aggron?
I've been trying out Megaggron online in-game to see what it can do with a 4 HP/252 Atk/252 SpDef spread, and from my experience, investing in Aggron's special defense isn't worth it. Adamant is pretty much required, since otherwise he doesn't deal enough damage, so Careful is out of the question, and even with max special defense IV and EVs, he still doesn't take special hits well enough to consider going for special defense, so you might as well dump his EVs into HP or defense. The only thing special defense EVs help with are Tyranitars carrying Fire Blast.
And I've been testing out ResTalk. Even then, you're better off with Defense, there's just too many opponents that are purely physical in this new meta.I've been trying out Megaggron online in-game to see what it can do with a 4 HP/252 Atk/252 SpDef spread, and from my experience, investing in Aggron's special defense isn't worth it.

Think maybe aggron should just stay away from special defense and run sylveon as a sp. def wall buddy? They practically perfectly work together. I see no reason to sacrifice EV's into sp def, when it wont make much a difference.
Unless someone can confirm that 252/252 in HP/SpDef actually makes him very bulky? Otherwise, screw it and start building a team instead of the perfect mon.
Welcome to the difference between a physically defensive and specially defensive Aggron. Tyrantrum's +1 Crunches do 25% instead of 32%, and Earthquake Mega Gyarados* does 34% instead of 42%. Dunno how you got 2HKO'd.Just tried out the following Aggron in a few wifi battles
Aggron@Aggronite
252 HP/252SpD/4 Attack
-Dragon Tail
-Heavy Smash
-Rest
-Sleep talk
It failed miserably. My damage output was puny due to the tank setup, and this guy even was having trouble taking Tyrantrum's Crunches after 1 Dragon Dance. Then he got 2HKO'd by Mega Gyarados' Earthquake. I was hoping to be able to tank physical attackers all day, but they were just able to get set up even through the phazing and KO me.
This and ttar make an excellent defensive core with sand partially covering up that bad 80 defense,for megaggron.
This and ttar make an excellent defensive core with sand partially covering up that bad 80 defense,for megaggron.Might actually make a stall team,centered around meggagron,tho mega ttar isnt a bad choice either,but 230 base defense is too good to pass up. Megaggron,tanking hits from MMX since october 12th 2013
Mega Aggron is a pure Steel type, so no Special Defense boost in Sand.
