  • Little Cup


Despite often being overshadowed by Little Cup's other Rock- and Ground-types, Onix has created a niche for itself in that it is one of only two common leads in Little Cup that use Explosion. With Explosion and its above-average Speed, Onix is able to not only set up Stealth Rock, but also bring something down with it. Despite its usual reliability, it is still beaten by a number of common leads, most notably Snover, which easily OHKOes it. Nonetheless, you will find that Onix is a solid choice for most teams.

Onix is able to do one thing extremely well: set up Stealth Rock. It is able to do this reliably by abusing two key attributes: its Defense and access to Explosion. With its sky-high Defense, Onix can laugh at the attacks Meowth and other Fake Out leads rely on to cause damage, while Onix sets up and starts firing off attacks. Onix can attack with either Earthquake or Stone Edge, as both receive the STAB boost and provide excellent coverage. In the final move slot, Explosion can get Onix a surprise kill once it has finished its job, while Taunt can stop every lead bar Diglett, Gligar, and Anorith from setting up entry hazards.

Other Options

Unfortunately, Onix has a relatively shallow movepool, so any sets it does run are fairly limited in options; however, Onix is able to run a set designed for use in sandstorm. Thanks to its Rock typing, Onix receives a substantial boost to its Special Defense in sandstorm, allowing it to successfully work in conjunction with Lileep. Onix is also capable of running a Rock Polish set, but it is outclassed in this regard by other Rock- and Ground-types, such as Rhyhorn and Geodude.

Checks and Counters

There are a variety of leads that give Onix trouble. Snover and Machop can both OHKO Onix with a STAB attack combined with a priority attack. Aipom can take Onix out with Fake Out and Seed Bomb before it can hit back. Not only can Diglett set up on Onix, but it also outspeeds it and can fire off a faster Earthquake. With a combination of Waterfall and Aqua Jet, Kabuto can render Onix useless.

Gligar is bulky enough to absorb a Stone Edge and fire off its own Earthquake. Bronzor, though afraid of Taunt, laughs off any attack Onix throws at it and sets up whatever it needs to. Onix is prone to priority, taking super effective damage from Ice Shard, Mach Punch, Vacuum Wave, and Aqua Jet; as such, any moderately powerful priority user will make short work of Onix.
