Overpowered Pokémon

[Blocksystem]

Who are your favorite, most overpowered Pokémon?
For me, I am going to have to go with my Mewtwo. While mega evolved, it has a whopping 500 special attack (max possible is 535 with perfect IV's and nature Mega Mewtwo Y) and has swept even teams consisting of just legendaries. Not to mention, it has more than enough resistance to take a few hits and recover away the damage.
Special shoutout to my Xerneas, who slaughters when pumped up with a 1-turn Geomancy.
Who is your favorite overpowered pokémon?

I love my Yveltal! I have have added fly to his list of attacks and pretty much left him alone. He is level 90 right now and there is only one trainer in the E-4 that has a mon that can hurt him (cant remember who atm). Aurora beam is awesome when he is hurt because it causes massive damage and returns 1/2 the HP back! I have not used my MewTwo much in Y as I have used him in the past to obliterate everyone, I wanted to try something new this time.

My most overpowered is probably my dear Mewtwo-X with his all-out physical attacker movepool. Non-legendary though, probably my Rotom-W. When with Choice Specs, magic happens... undeniable magic...

I'd have to say Mewtwo as well, both Mega Forms with great natures are really powerful and can overpower most Pokemon. Mega Mewtwo Y even has the highest base speed now. Mega Gengar as another overpowered one as well, with high Speed and some great moves in its moveset.

mega khagesthan is sooooooo over powered with power up punch he can defeat anyone !!!

 

[KarlG]

Has anyone tried Mega-Kangaskhan with Power-Up Punch? That is a monster.

 

[Axe to Fall]

Elektross, Salamence, Gyarados, Rayquaza, Furfrou.

 

[Johan]

Mega-Blaziken with Protect and Sub. Screw that.

Cofagrigus says hello. Power Punch and Return can't hit it. Plus it's brilliant ability Mummy negates its signature ability, Parental Bond. Then there's the fact that Cofagrigus has a massive base defense stat of 145 so Mega Kangashkan can't really do a whole lot against it. If you can get off will o wisp against it then it's a sitting duck.

Mega Kangaskhan with Crunch/Sucker Punch say hi, Cofagrigus has a pitful 58 base HP so even with 145 base Def he's not gonna survive a Crunch from Mega Kangaskhan.

exactly
but the best opponent for mega kangakhan
is probably a dark / ghost type pokemon with fighting type moves or DISABLE hehe

 

[Ziggy Stardust]

Talonflame. It's kinda the revenge of the Com Mons.

Mega Venusaur is overpowered defensively with my experience with it. Calm Nature, maxxed defenses, flawless IVs, a good moveset, and its Ability Thick Fat allow it to last quite a while in battle. Still tough to stand against Flying and Psychic types though.

 

[Almonds]

I don't know if it counts, but maybe Volcarona? It has been a life-saver to me countless times.
Also, if she counts, Mega-Aggron. I never saw anyone use Mega-Aggron anywhere, but that defense is brilliant. Also, pro Filter.

Whimsicott
Something so adorable shouldn't be this lethal. With Prankster there are few opponents that can stand up to it. I don't think any of the legendaries can counter it. Those genies have access to Prankster, but aren't the best candidates to fully utilize it. Also, dat speed leaves few, if any, priority users who could break through substitute.

 

[Jaguarfire]

Giratina, Xerneas and does Shaymin count? They look awesome and are just as powerful

 

[Slim_Hiiipower34]

Blaziken before and after mega
In gen IV and V I dominated whole teams with just blaziken and now mega blaziken speed boost
FORGET ABOUT IT

Blaziken before and after mega

I second this choice! Only my Mega Blaziken with Speed Boost could take on a Genesect and a Darkrai with a 30 level disadvantage.

 

[poketshroom12]

Alakazam.
Has a monsterus special attack base stat and a awesome move pool with attacks like charge beam, shadow ball, dazzling gleam, thief, and many others. He is also the smartest pokemon besides slowking and metagross with an IQ of 5,000. In his mega form, he is just as fast as mega Blaziken and could KO it with just one psyshock.
