Basics
Onix is a Rock/Ground-type Pokémon. Its 100% IV CP is 629 at level 20 (raids, eggs and research), 787 at weather-boosted level 25 and up to 1,245 at level 50. It is most vulnerable to Water/Grass attacks (2.56×) and also weak to Ice/Fighting/Ground/Steel attacks (1.6×). It resists Normal/Fire/Flying/Rock/Electric/Poison attacks. In raids, Tackle + Breaking Swipe is its strongest moveset (level 40, 100% IVs). It evolves into Steelix with 50 Candy and Metal Coat. As your buddy, it earns 1 Candy every 5 km you walk together.

Onix has a magnet in its brain. It acts as a compass so that this Pokémon does not lose direction while it is tunneling. As it grows older, its body becomes increasingly rounder and smoother.

- How to read IVs and appraisalsIVs run from 0 to 15 for each of Attack, Defense and HP, and appraisal stars are set by the sum of the three (0–45).
- What to power up first (power-up priorities for beginners)Stardust is limited, so first power up strong counters you'll use for a long time across many raids.
- Choosing IVs for PvP (low Attack wins in Great and Ultra League)In leagues with a CP cap, the lower the Attack IV, the higher you can level up within the same CP, which makes Defense and HP bigger.
