Let me just put into perspective how, in my opinion (I respect the input of everyone as everyone has a SOLID ROCK right to an opinion!), Mega Pidgeot isn't THAT broken or even over-centralizing in UU!
252 SpA Mega Pidgeot Hurricane vs. 248 HP / 232+ SpD Mega Ampharos: 63-75 (16.4 - 19.5%) -- possible 6HKO Yum!
28 SpA Mold Breaker Mega Ampharos Volt Switch vs. 4 HP / 0 SpD Mega Pidgeot: 288-338 (93.5 - 109.7%) -- 56.3% chance to OHKO BOP!
252 SpA Mega Pidgeot Hurricane vs. 248 HP / 252+ SpD Rotom-H: 63-75 (20.7 - 24.7%) -- possible 5HKO after Leftovers recovery Tasty!
0 SpA Rotom-H Volt Switch vs. 4 HP / 0 SpD Mega Pidgeot: 188-224 (61 - 72.7%) -- guaranteed 2HKO Could be trouble!
252 SpA Mega Pidgeot Hurricane vs. 0 HP / 0 SpD Mega Aerodactyl: 96-114 (31.8 - 37.8%) -- 92.7% chance to 3HKO This is not even a bulky mon, let's go!
212+ Atk Mega Aerodactyl Stone Edge vs. 4 HP / 0 Def Mega Pidgeot: 432-510 (140.2 - 165.5%) -- guaranteed OHKO RIP!
252 SpA Mega Pidgeot Heat Wave vs. 248 HP / 252+ SpD Empoleon: 76-90 (20.4 - 24.2%) -- possible 6HKO after Leftovers recovery Bulking all day long!
0 SpA Empoleon Scald vs. 4 HP / 0 SpD Mega Pidgeot: 114-135 (37 - 43.8%) -- guaranteed 3HKO + the ability to phaze out...yeah lol
252 SpA Mega Pidgeot Hurricane vs. 0 HP / 4 SpD Assault Vest Snorlax: 114-135 (24.7 - 29.2%) -- 99.9% chance to 4HKO even without HP or SPDef investment!
252+ Atk Snorlax Return vs. 4 HP / 0 Def Mega Pidgeot: 196-232 (63.6 - 75.3%) -- guaranteed 2HKO Yeah...lol
I know I'm probably going to get replies saying that hurricane causes confusion 30% of the time and that it's luck based and can be abused and this and that! Here's the thing..you have moves like Body Slam, sludge bomb, scald, lava plume (there may be more moves I missed that has a 30% chance to cause something) that has a higher than average chance to hax someone, but that's 70% of the time that it won't work. Even if it happens everytime, that's just part of the game. Anything can happen, not just because you use Mega Pidgeot. Also, a nugget of info, No Guard works for everyone involved on the field! Sure hurricane can't miss with no guard, but that means your opponents attacks will land without fail as well. Keep that in mind as well as some calcs that are shown here! Calcs don't lie friends :]
