ONIX Slot 1 Slot 2 Slot 3 Slot 4 Earthquake Rock Slide BindScreech Explosion Move Effect Type Pwr Acc Earthquake Damages the target. Ground 100 100% Rock Slide Damages the target. Rock 75 90% Bind The user becomes uncontrollable and attacks for 2-5 consecutive turns; the target cannot make attacks of its own during this time, but it may switch out, use items or run away. Normal 15 75% Screech Lowers the target's Defense by 2 stages. Normal N/A 85% Explosion The Defense stat of other Pokemon is halved against this attack, essentially doubling the move's base power; causes the user to faint. Normal 170 100%           Other Options: Sharpen (NYPC) Verdict: With Rhydon and Golem around, one has to wonder why Onix even exists. Even if those other two Rock/Grounds weren't around, Onix still wouldn't be that good, since all it has going for it is its massive Defense, and even that is negated by horrible HP. Onix has decent Speed, however, and can annoy standards like Chansey with its Bind. What really kills Onix, though, is his terrible Attack. Earthquake, Rock Slide and Explosion are all good moves, but Onix will have to Screech to be able to KO anything and, even then, Blizzards, Surfs and Psychics are flying all over RBY to cut Onix down before he can wear down the opponent's Defenses. Trade it to GSC where it evolves into something worth your time.
