Onix
Plan this partner in PokéBonk
This analysis describes the Onix League partner and its evolution line, not necessarily the current form alone.
Heavy armor, extra HP and automatic falling rocks make Onix sturdy from the start. Its sweeping Ultimate and Rock Snake fusion offer clear area payoffs.
Trade-off: Reduced movement speed and no built-in recovery make prolonged chip damage a concern.
Passive: Rock Head
Ultimate progression: Rock Snake
Curated kit: Rock Tomb (Lv. 1) · Stealth Rock (Lv. 2) · Iron Tail (Lv. 4) · Head Smash (Lv. 7)
Later moves become eligible offers; they are not automatically equipped.
League analysis and kit: v0.8.25, checked October 23, 2026. Individual unlock checklists and linked builds carry their own source dates.
