Sorry for the lack of updates, but I had exams this week so had to study, this article’s pretty good though so it’s worth it right? Right?

Mewtwo has been around since the first generation and has been obscenely powerful the whole way through. Nobody, and I mean NOBODY doubts that Mewtwo is an Uber Pokemon. In fact, it’s up there as one of the very best Ubers. In the right hands it can be completely devastating in that environment.
Access to the best Special moves in the game; excellenet set-up moves; good Physical moves for unpredictability; and some of the most insane stats in the game mean thatif you know what you’re doing then it really might as well be game over as soon as Mewtwo hits the field.

Movesets
Calm Mind set up
Mewtwo @ Leftovers
Timid Nature (+Speed -Atk)
EVs: 40 HP / 252 SAtk / 216 Speed
Ability: Pressure
- Calm Mind (Raises Mewtwo’s SAtk and SDef 1 stage. Learned by TM04)
- Recover (Restores 50% of Mewtwo’s HP. Learned at lvl 86)
- Ice Beam (95/100. Ice. Special. 10% chance of freezing opponent. Learned by TM13)
- Taunt (Forces opponent to use offensive moves. Learned by TM12) OR Aura Sphere (90/-. Fighting. Special. Learned at lvl 100)
Looks simple enough, to realise the full devastating potential of this monster requirs a bit of skill, but it’s pretty easy to understand.
Set up a Calm Mind on something that would fear Mewtwo. Most Ubers are Special hitters and most of those that use Physical moves are Ice weak. So after two or three Calm Minds Mewtwo becomes practically untouchable.
Recover should be easy to understand on a fairly brittle Pokemon that needs to survive to set up, any time Mewtwo’s health runs low just Recover it back up.
Taunt’s main use is to stop other Calm Minders setting up on you, it also prevents status which would not be fun for Mewtwo. As an additional bonus it prevents opponents healing themselves so Mewtwo can destroy them. Basically Taunt prevents anything from beating Mewtwo by methods other that having to KO it, which works wonderfully with Calm Mind’s boost and Recover.
Ice Beam is a fantastic move in Ubers, nothing is immune to it, the only things that resist it are Kyogre, Manaphy, Metagross and variour Arceus forms (Those ones are rarely used though), and it is also super-effective on quite a few of them. This makes it ideal to use as a sole attacking move; however if you feel that isn’t enough you can go with Aura Sphere, this is an option to allow Mewtwo do defeat Tyranitar and Darkrai, two Pokemon that ruin any efforts of Mewtwo’s unless it has an amount of Calm Minds anyone with those two Pokemon should not be letting it have.
Put simply, if this thing can set itself up your opponent might as well just hit Run. As nothing barring a critical hit from a Deoxys-A Shadow Ball (As nothing else which would KO Mewtwo even with the crit will outspeed it) will stop it completely destroying your opponent’s team. Make sure to play smart though, unless you have at least two Calm Mind’s up don’t fool yourself into thinking you can just survive anything.
Make sure it’s counters are gone though, even with Mewtwo’s fantastic Special Attack there are some things that will be able to beat you because Mewtwo isn’t versatile enough with this set. Check the counters at the end of this post and make sure you’re able to beat them before you even consider battling with this in your team.
I almost forgot! You may be wondering with Psychic isn’t used on this Pokemon, surely STAB would be of use right? Wrong. Psychic hits nothing super-effective in Ubers except Arceus forms, while Fighting Arceus is used, one specific incarnation of a Pokemon, especially when so many Pokemon resist Psychic in Ubers, is not enough to use a move. Mewtwo has enough power anyway.
Special Sweeper
Mewtwo @ Choice Specs or Life Orb
Timid Nature
EVs: 40 HP / 252 SAtk / 216 Speed
- Aura Sphere
- Ice Beam
- Shadow Ball (80/100. Ghost. Special. 20% chance of SDef drop. Learned by TM30)
- Thunder (120/70. Electric. Special. 30% paralysis chance. Learned by TM25)
Nothing like the last set really. Where the last one focussed on setting up and winning the whole game, this focuses on just killing anything that moves on the opposing team. Specs gives it 610 Special Attack and 529 with Life Orb, so you can imagine this will leave quite a dent in anything stupid enough to do the aforementioned moving.
Aura Sphere is again for destroying Dark types which like abusing Mewtwo’s weak to their STAB moves, in addition to that it lets Mewtwo hurt Dialga quite a bit.
Ice Beam is again used because practically nothing resists it, this should probably be the move you use if nothing else seems suitable (As Mewtwo doesn’t pack STAB this is actually his most powerful fully-accurate attack).
Shadow Ball beats all those Psychic types in Ubers, Psychic is a very common type so having a move that will hit most of them regardless of second types helps.
Thunder is great in Ubers courtesy of the rain brought by Kyogre, it also allows Mewtwo to destroy said Kyogre as well as being Mewtwo’s most powerful move while the rain is in effect.
OK, saying 610 Special Attack is good enough, but what will really make this thing impressive is showing you the amount of damage it can do (All Pokemon will be EVd defensively as Smogon recommends. Damage over 53% is a 2HKO if Leftovers are on opponent. 37.3% is a 3HKO)
vs Lugia
Shadow Ball: 43.27% - 50.96% (LO). 50% - 58.89% (Specs)
Ice Beam: 51.20% - 60.34% (LO). 59.13% - 69.47% (Specs)
Thunder: 64.42% - 75.72% (L)). 74.28% - 87.50% (Specs)
vs Giratina
Shadow Ball: 43.85% - 51.59% (LO). 50.60% - 59.52% (Specs)
Ice Beam: 51.98% - 61.11% (LO). 59.92% - 70.44% (Specs)
vs Dialga (Dialga has multiple EV spreads, these are for the Toxic Stall, as it is very defensive).
Ice Beam: 36.39% - 42.82% (Specs)
Aura Sphere: 59.90% - 70.54% (LO). 69.06% - 81.44% (Specs)
vs Latias
Shadow Ball: 62.76% - 73.57% (LO). 72.37% - 84.98% (Specs)
Ice Beam: 74.17% - 87.09% (LO). 85.59% - 100.60% (Specs)
Those are just common walls, pretty much everything else is so weak to Mewtwo’s attacks they will be 2HKO’d without a doubt (The two exceptions are Blissey and defensive Arceus).
I personally prefer Life Orb as Mewtwo likes the extra versatility and it can KO well enough anyway, but if you feel the extra power of Specs suits you then it’s your choice.
This should have demonstrated to you how truly devastating Mewtwo is. A guaranteed 2HKO on all but a few Ubers with Life Orb means this thing is great any time in a game, able to give some good early damage and mop up a team at the end, it really is that deadly.
Surprise Physical Mewtwo!
Mewtwo @ Life Orb
Jolly Nature
EVs: 40 HP / 252 Atk / 216 Speed
- Selfdestruct (200/100. Normal. Physical. Halves opponent’s defence the turn it is used, Mewtwo faints. Learned by XD’s Move Tutor)
- Ice Punch (75/100. Ice. Physical. 10% freeze chance. Learned in Emerald Move Tutor)
- Bulk Up (Raises Mewtwo’s Atk and Def by one stage. Learned by TM04)
- Brick Break (75/100. Fighting. Physical. Breaks Reflect and Light Screen. Learned by TM31) OR Earthquake (100/100. Ground. Physical. Learned by TM26)
This may look stupid but it’ll catch anything fighting it completely by surprise, Base 110 Attack isn’t bad either.
Bulk Up gives Mewtwo some power to use behind its moves; as, even with the element of surprise and the fact most Ubers EV Special Defence, you won’t do much damage with this set relying on no boosts.
Selfdestruct is just awesome on anything and goes really well with Life Orb as the extra damage won’t hurt you when you’re already fainted. This can be used to give Mewtwo one final shot when it’s near the end of its sweeping, and just if you need an emergency KO if something is destroying your team.
Ice Punch is basically Ice Beam but Physical, I don’t think I have to explain it again.
Brick Break can be used to obliterate Tyranitar, Darkrai and Blissey but you’ll probably want Earthquake as this set really is low on Base Power and the ability to whack Metagross, Dialga and the aforementioned Tyranitar isn’t that bad.
Basically the main use of this set is to try and take something out by complete surprise, hopefully beat something else then blow up for another KO, pretty scary.
Counters
Blissey will stop all Special version cold so if running Life Orb on the Special Sweeper you might want Selfdestruct to prevent Her Royal Fatness from walling you silly. The same applies to defensive forms of Arceus that aren’t weak to any of Mewtwo’s attacks (Fighting springs to mind, as does Bug). Metagross also works well as it isn’t weak to any of Mewtwo’s moves on the Special set and can beat it up with a Choice Banded Pursuit.
Anything that isn’t weak to one of Mewtwo’s moves should probably do the job, Mewtwo’s power is so immense though that unless your Pokemon is pretty bulky it won’t stand up to the absurd power of Mewtwo’s assault.
Where to find Mewtwo
Cerulean Cave in Fire Red/Leaf Green, it’s at level 70 there so watch out.
