Mega Aggron as a
hard counter. And why the fuck does Mega Glalie weigh almost 800 pounds?
Aggron-Mega @ Aggronite
Ability: Filter
EVs: 252 HP / 4 Atk / 252 Def
Impish Nature
- Heavy Slam
- Earthquake
- Stealth Rock
- Thunder Wave
Mega Bitch-tits can do what it wants to try and break Aggron, but the best move it has to beat Earthquake (itself a 5HKO with five consecutive maximum damage rolls) is Explosion, which, uh, yeah. Or Hidden Power Fire, but that's not listed and is also still a 4HKO.
Because Glalie is for some reason absurdly heavy, Heavy Slam only hits with 40 BP, but that in itself still has a 70% chance to 2HKO (46.5 - 55.8%), and you paralyze with Thunder Wave, set up Stealth Rocks, etc. Basically, Mega Aggron laughs at Mega Glalie.
