THE MONSTER SMASH!

Skeleton is 1st hide tab
[Overview]
<p>With poor Special Defense, HP, and Speed stats, one may question why Omastar deserves to be used in the Uber realm. The answer is simple: Omastar's ability, Swift Swim, when used in conjunction with Shell Smash, its high Defense stat, and Rock typing, enable Omastar to transform itself into a fearsome sweeper that cannot be revenged in the rain. With the ability to deal over 80% damage to Ferrothorn with a Hydro Pump, it would be unwise to underestimate the fossil, lest you wish to be drowned in the depths of the sea. Do not let this lead you into thinking Omastar is perfect though -- its poor base Speed haunts it, as it is possible to revenge the fossil with a scarfer should the rain provided by Kyogre be taken away by Groudon or Tyranitar. All-in-all Omastar is like any other sweeper: support it well, remove its checks, and you will have a monster in your hands.</p>

[SET COMMENTS]
<p>Omastar's ability combined with a high base 125 defense stat and its Rock typing allows it to become a very good revenge killer in the rain, capable of revenging even ExtremeSpeed Arceus. Omastar's access to Shell Smash enables it to excel at this role, as it can punish teams that dare try to switch out the pokemon that is to be revenged, will be promptly met with a monster that OHKOes the metagame after Stealth Rocks and two layers of Spikes.</p>
<p>Shell Smash is the crux of the set, allowing Omastar to boost its Special Attack stat to sky-high levels, and makes it impossible to revenge under the rain. Hydro Pump provides immense power, allowing Omastar to deal over 80% to Ferrothorn in the rain; however, due to its poor accuracy, one may choose the alternative Surf for more reliable yet less powerful damage. Ice Beam provides fantastic coverage with Surf, hitting Giratina-A for super effective damage, as it is one of the few pokemon that are not OHKOed by Hydro Pump after Stealth Rocks and Spikes. Lastly, Earth Power enables you to hit Dialga for an OHKO, as it also is not OHKOed by Hydro Pump. However, due to the fact this leaves you walled by the likes of Gastrodon and at the mercy of opposing Water-types, it may be more desirable to use Hidden Power Grass to achieve perfect neutral coverage.</p>
[ADDITIONAL COMMENTS]
<p>Omastar appreciates Stealth Rock and Spikes support to increase the number of OHKOes it achieves. Ferrothorn is a great candidate to supply these due to the great synergy it gets from Omastar. Omastar in return can stomach Choice Scarf Fire Blasts aimed at the durian fruit and use them to set up a Shell Smash. These two also appreciate Kyogre support, as it lets the fossil activate its Swift Swim and decreases the amount of damage Fire-type moves do to Ferrothorn.</p>
<p>Omastar normally relies on bluffing a revenge kill to set up a Shell Smash, which requires high prediction. Due to this reason Omastar appreciates Wobbufet and dual screen support, as both allow Omastar to have a much easier time Smashing. The latter deserves a special mention, as it effectively negates Shell Smash's defense drops for a small amount of time. If you feel that it is too risky too bluff a revenge kill and do not want to waste a slot on your team for Wobbufett or dual screen support, Omastar can set up in the face of a Choice Scarfed Fire Blast or Ice Beam from the likes of Palkia and Kyogre.</p>
<p>Since Omastar is designed to be a revenge killer, plenty of Pokemon appreciate the ability to drop their scarf in exchange for an item to boost the damage their attacks do or utilize leftovers. Palkia deserves a special mention, as it can bluff the standard Choice Scarf set and utilize Lustrous Orb to help take out the likes of Ferrothorn and Giratina-A, two pokemon that can halt Omastar's sweep as they live a Shell Smashed Hydro Pump.</p>
[Other Options]
<p>Omastar can utilize attacks other then those listed in its set, but sadly those attacks do not provide much coverage and are often outclassed. Omastar can utilize Ancient Power, as it gets a STAB boost, but sadly, it's STAB does not complement Hydro Pump very well, and is fairly weak. If you fear Ferrothorn then you may opt to use Hidden Power Fighting, as it deals a massive amount of damage to Ferrothorn in sun, should the rain Omastar desires be taken away from it. More often then not, however, the moveslot is wasted, as Ferrothorn takes around the same damage from a Hidden Power Fighting as it does from a Hydro Pump in the rain. Omastar can lastly utilize Toxic on a Shell Smash set to hit Shedinja switch-ins and OHKO them, should you not be able to provide entry hazard support. Omastar can also take advantage of Swift Swim and the fact it receives Stealth Rock and Spikes to make a decent lead. However, such a set is often outclassed by Qwilfish, which has not only higher speed, but Taunt, Explosion, Toxic Spikes, and Destiny Bond. Omastar's only advantage over Qwilfish is Stealth Rock, which gives it some viability should you wish to use it.</p>
[Checks and Counters]
<p>If Omastar smashes, pray to Arceus that it runs Hydro Pump and that its blast of water misses its intended target, as chances are more then likely it will sweep your team. Unfortunately, despite the raw power Omastar brings, it cannot OHKO the whole metagame should it lack entry hazards. If this is the case, Palkia, Ferrothorn, specially defensive Giratina-A, specially defensive Lugia, and Bulky Kyogre, can all live a move and phaze the fossil or OHKO it, destroying its chances to sweep. If Omastar manages to set up a Shell Smash with the hazards it requires to OHKO the metagame, or you lack a Pokemon that can take a hit and OHKO back, then Groudon can be used to neuter its "impossible to revenge status", as even after a Shell Smash, Omastar's poor speed drags it down as it cannot outspeed anything upward from a Choice Scarfed base 90 should it lack rain or a second Shell Smash boost. Sadly, the behemoth that provides sunlight, Groudon, cannot handle the agonizing power of any of the fossil's moves and will likely fall when replacing rain with sunlight.</p>
<p>If this cannot be achieved, then it may be desirable to scout what moves the fossil has. If Omastar lacks Earth Power, then Dialga can also take a hit and revenge the fossil. On the contrary, should Omastar lack Hidden Power Grass, then Gastrodon can wall the fossil, as it will not OHKOed by any move. If you still lack any Pokemon to take a hit, then you might as well try to prevent its chances of sweeping your team completely. Scizor and Thundurus can sacrifice themselves to cripple Omastar for the rest of the match. The former deals a massive amount of damage to Omastar with a Choice Banded Bullet Punch (does not OHKO though) and the latter is capable of bypassing its Speed, courtesy of Prankster, and can cripple it with Thunder Wave. Similarly, Whimsicott can bypass its speed and cripple it with Stun Spore, Grasswhistle, and Encore. Lastly, if the user of Omastar lacks hazards, then Shedinja shall wall it unless Omastar has Ancient Power or Toxic. This is only assuming Omastar has already Shell Smashed though, if you can prevent the monster from smashing by stopping Wobbufett or a dual screener, then you will have avoided a crisis.</p>

Checks and Counters:
Also I think I'm biased towards this guy... might just be me though.
- Really bad typing
- Horrible HP stat
- 55 base speed = yuck
- Not the greatest SpD stats either...
- Gets Shell Smash and Swift Swim!
- Hits hard after it smashes
- 115 Defense with Rock typing means Exkiller can't revenge it.
- Oh wait Swift Swim + 2 speed.... yeah CAN'T BE REVENGED IN RAIN!
- Needs Wobba (most of the time)
- Opposition needs Sun + Scarfed Revenge killer to deal with this guy or Vaccum Wave (but thats non-existent).
- DEALS 80+% to FERROTHORN with a + 2 PUMP!
- Sadly can be revenged without Rain but its a nightmare if it sets up...
- Reliable revenge kills Exkiller without Smashing, pretty good quality :D.

item: Life Orb
ability: Swift Swim
nature: Modest
evs: 4 HP / 252 SpA / 252 Spe
Why it deserves to be on site:
- Hits really hard
- 2HKOes whole meta after a smash
- Near impossible to revenge
Set Comments:
- Shell Smash boosts stats
- Hydropump and surf hit harder then Specs Kyogres... pick and choose your weapon
- Ice beam is good coverage hits Gira-a (phaser not OHKOed by pump for SE damage.
- Earthpower hits Dialga hard, HP Grass completes perfect coverage (trolls gastrobro).
Additional Comments:
- IT LOVES HAZARDS!
- SR + Spikes near mandatory as to enables it to OHKO the whole meta!
- Can use less speed to invest more in bulk, also mental herb is usable but YOU WANT TO OHKO THE WHOLE METAGAME WHY WORRY OVER THAT SMALL STUFF!
- THE SEA LEVIATHAN GIVE YOU RAIN, IT GIVE YOU THE SWIFT SWIM TO DESTROY META. Kyogre is mandatory to activate swift swim. Perfers rest talk since they nicely combat Groudon and have longevity.
- IF YOU NO WOBBA, YOU NO SMASH (You need Wobba to smash, but technically still pretty good at revenging in rain). Chances of smashing without wobba are slim although unlike other stuff you can bluff the revenge kill and turn the world into kyogre's own private hell.
- Lustrours Orb Palkia is a great partner since it takes out Ferrothorn. Ferrothorn can switch into it on its smash and since it barely does not OHKO, effectively countering it. By running Omastar, Palkia no longer needs scarf since Omastar revenge kills (Swift Swim) meaning Palkia can go Lustrous Orb and debilitate Ferrothorn with a Fire Blast. Omastar also helps more well by pretty much crippling every single Special Sponge in the game :P.
- Timid is usable to outspeed all scarfed base 90s after a smash without rain but the powerloss is noticiable... once again YOU WANT TO OHKO THE META, Chances are you won't be revenged anyway... but if you want extra insurance for not getting revenged, timid is > modest.
- Dual Screens over wobba are usable to allow smash + bulk after smash.
- Sets up on choiced Ice beam if neither screens nor encore can be provided.
Other Options:
- Spiker set but outclassed by Qwilfish, gets Sr though so... still slightly viable.
- HP Fighting is usable should Omastar meet ferrothorn in sun after smashing.
- Ancient Power is STAB but its Stab doesn't complement HPUMP, still usable though.
- Toxic to hit shedinja
Checks and Counters:
- Uh if it smashes pray to Arcues that you have psychic abilities.
- Specially Defensive Giratina-a barely lives Ice Beam and Dragon Tails it out, IS 2HKOed however, meaning it needs to switch-in on smash.
- All standard (not those odd ones designed to outspeed Mewtwo) choice scarf base 90s outspeed Omastar at + 2 without rain or in rain prior to smash.
- Groudon brings Sun really weakens its killer Hydro Pump and removes swift swim, problem is that Groudon gets obliterated by Omastar.
- Specially Defensive Lugia if that exists.
- Light Screen turns its OHKOes into 2HKOes.
- Whimsicott makes it cry... Priority Encore destroys its attempts to smash, Stun Spore cripples it, EVEN GIGA DRAIN OHKOES IT!
- Point stated don't let it smash = stop wobba.
- Shedinja... no comment...
- Palkia lives everything at +2 BUT IS 2HKOed, and it cannot revenge without surviving a hit so it has to switch in on the smash.
- Kyogre does the same as Palkia but it needs a bulkier spread to do so... however no investment scald does OHKO so don't worry about that CONCENTRATE ON ELIMINATING THE MONSTER SMASH!
- Thundurus has priority twave but it probably will die crippling it D:.
- Scizor's choice banded bullet punch HURTS, although it does not OHKO it puts Omastar's sweeping days to a limit. (does 61.7% - 72.7% after Omastar smashes for those curious).
- Gastrodon destroys Omastar without HP Grass... if it has HP grass though it will be cleanly OHKOed.
Also I think I'm biased towards this guy... might just be me though.
