Bellossom @ Wise Glasses
Trait: Chlorophyll
EVs: 252 SAtk / 129 SDef / 129 HP
Modest Nature (+SAtk, -Atk)
- Energy Ball/Giga Drain
- Dazzling Gleam
- Sleep Powder/Stun Spore
- Sludge Bomb
Pretty much the standard set with a few improvisations. With the new Fairy type, and Bellossom able to learn one of the more powerful Fairy moves, it is able to wreak havoc on some Dragon/Fighting types that think they can just come in and set up. Energy Ball or Giga Drain, both are equally as good. Energy Ball for the power or Giga Drain for health recovery. Sleep Powder or Stun Spore is pretty much a given - although I'd suggest running Stun Spore because it lasts for the whole battle and Bellossom's speed stat isn't the greatest. Sludge Bomb is pretty good against fellow Grass types, and with a high chance to poison it's an all round good move. Not to mention the 30% boost it gets to all its Special Attacks from the Wise Glasses.
Bellossom @ Leftovers
Trait: Chlorophyll
EVs: 252 HP / 252 SDef / 4 Def
Calm Nature (+SDef, -Atk)
- Venoshock
- Toxic
- Infestation
- Synthesis/Moonlight
This is one of my favourite Bellossom sets for Gen VI. This thing can tank Special Attacks like there's no tomorrow, and is a great staller as well. Infestation traps your opponent - so that Blissey can't switch out and get Natural Cure, and that Slowbro can't get its Regenerator - as well as dealing residual damage each turn. Next is Toxic, which does increasing residual damage that piles up for the four to five turns that Infestation is active. Since the foe is poisoned, Venoshock raises to 130 base power. Synthesis or Moonlight allows you to keep Bellossom alive longer, although I'd recommend Moonlight in case your opponent decides to use Rain Dance.
Bellossom @ Life Orb
Trait: Chlorophyll
EVs: 252 Atk / 129 Def / 129 SDef
Adamant Nature (+Atk, -SAtk)
- Swords Dance
- Petal Blizzard/Leaf Blade
- Sleep Powder/Stun Spore
- Drain Punch
P.O.B.: (P)hysical (O)rientated (B)ellossom. Swords Dance give amazing power to its Physical Attacks. Petal BLizzard or Leaf Blade are equally as good, both have the same power except Leaf Blade has a higher chance of a Critical Hit. Sleep Powder is a pretty good move, but - as stated previously - can be substituted with Stun Spore to just be that much more annoying. Finally, Drain Punch does damage and recovers health at the same time; pretty much a Physical Giga Drain.
