<p>This is the Metagross Lead we're all used to, but modified to be a much more offensive version. nstead of wasting a turn Stealth Rocking the main goal becomes simple. Kill the opponent as fast as possible. It beats a LOT of leads. Examples:</p>

<ul><li>Metagross: Outspeeds and uses Earthquake for the 2HKO. An easy win as long as you can outspeed.</li>

<li>Azelf: Iron Head + Bullet Punch OHKOs 100% of the time. Flamethrower only can burn.</li>

<li>Swampert: Explode right in his face, preventing Stealth Rocks. The day Swampert Protects first turn I'll shove a broom in my ass.</li>

<li>Jirachi: Earthquake 2HKO's and it can't do anything to Metagross back bar switching, which means that it lost.</li> 

<li>Aerodactyl: Aerodactyl loses to two consecutive Bullet Punches and it's Earthquake doesn't even 2HKO.</li> 

<li>Infernape: A Fake Out + Fire Blast is incapable of 2HKO'ing Metagross even with Blaze activated, while EQ + Bullet Punch finishes Infernape. It must choose between damaging Metagross and getting SR up, usually meaning a 6-5 for the Metagross user.</li> 

<li>Hippowodon: OHKO with Explosion.</li> 

<li>Ninjask: Doesn't stand a chance. All the speed boosts mean nothing when Bullet Punch proceeds to hit Ninjask before it can make a sub. Even if Ninjask performs a successful pass, it is nearly impossible to get past Metagross, who has Bullet Punch and Explosion to deal with the new threat.</li>

<li>Bronzong: While Iron Head deals little damage (20%) Earthquake will usually 4HKO me in return. It takes two Iron heads to put Bronzong into Explosion KO range, so to prevent rocks (and start the game off rockless, 5-5) it needs two flinches in a row.</li>

<li>Tyranitar: Iron Head + Bullet Punch beats most TTar leads without much effort. 30% flinch occasionally starts the game off 6-5 with you at full health.</li>

<li>Heatran: If it knows better and just 2HKOs me with Earth Power, I lose. Some may actually SR, expecting me to do the same. I'll assume the worst case scenario here since even against standard SRing Occa leads, attacking right away is the best bet. </li>

<li>Abomasnow- Two Bullet Punches should take care of him easily. Either way, Abomasnow can do nothing back short of the odd Grasswhistle, which isn't even standard on the lead.</li>

<li>Smeargle- If Metagross absorbs the Spore (NOT Bullet Punching on turn 1) it has a 50% chance of waking up the following turn and 2HKOing with Iron head / Bullet Punch.</li>

<li>Gyarados- Metagross can Explode right away while Gyarados can only watch.</li> 

<li>Yanmega- If Yanmega carries Life Orb both pokemon will die (Iron Head + Bullet Punch + 2 LO recoils). With Focus Sash Modest Yanmega will 2HKO about 35% of the time.</li></ul>

<p>Results: Overall, it is successful against 86.67% of the leads seen. Stealth Rock isn't.
