Physical Sweeper Onix (Rock Head)

Onix is an extraordinary Physical Sweeper. It's meant to take down the opponent's team with brute physical power. Remember prior to Generation IV, a move's damage category was determined by its type. Onix is not a Pokemon anyone usually expects sees on the battlefield until it was realized Eviolite would make it quite viable. If Eviolite is held by a Pokémon that is not fully evolved, it will raises the Defense and Special Defense of that Pokemon by 50%. Focus Sash helps protect Onix from being one-shotted and allowing it to atleast use a crucial move when brought out. With Rock Head, Onix does not take recoil damage besides struggle/life orb/crash damage.

Earthquake is a physical STAB-boosted 100-base power Ground-type move (hits adjacent pokemon. power doubles on dig).
Dig is a physical STAB-boosted 60-base power Ground-type move (digs underground turn 1, strikes turn 2).
Double-Edge is a physical 120-base power Normal-type move (has 1/3 recoil).
