why it deserves to be on site
- easily can deal worth many common leads
- near perfect coverage with Stone Edge and perfect coverage with Shadow Claw
- Vacuum wave (although special) serves the purpose of KOing opponents that held on with a focus sash
- still a major powerhouse regardless of UU ranking
- a relatively bulky set, this allows it to deal with many other leads' attacks, and live to retaliate.
- Simple and effective play style means its easy to use, and it can still be used late game
- usually takes out 2 of the opponents pokes by the time he faints.

- shadow claw can be used for better neutral coverage as well as a more accurate fall back option. It also helps deal with things like Rotom-A that are manageable with Stone Edge, but are more effectively dealt with using Shadow Claw. Stone Edge is the recommended choice as it allows Heracross to deal with many switch ins (Primarily flying type such as Zapdos and Dragonite. As well as provide a stronger neutral hit to anything that resists Heracross's stabs (bug, ghost, flying, and poison)
- lum berry can be used to deal with sleep leads, although you sacrifice the safety of having focus sash, as well as the capability to deal with leads like Heatran.
- Vacuum Wave serves no purpose other than to pick off sashers. This is why adamant was chosen over something like naughty, as it was best not to sacrifice bulk to give Vacuum Wave a little more of a boost.
- The EVs were designed to maximize the amount of damage it could deal while preserving its bulk. The defensive EVs were picked using X-Acts defense effort value calculator.
- Heracross should generally be partnered with a water type, like Starmie, as they handle a lot of Heracross's major threats.
- Extreme physical walls, serve as checks, so something that can dispatch the likes of Skarmory and Hippowdon works well with heracross.
- The only leads Heracross generally loses to are hippowdon because of slack off, and infernape and metagross should they choose not to set up rocks. And dragonite can give it issues as well. Because of this, it is best to have some way of handeling them within the team.
