How to unlock Iron Moth
There is no direct purchase for Iron Moth. It appears on the Paldea banner inside the 4★ pool. The 4★ band takes 6.5% of all pulls and holds 211 partners, so one specific Iron Moth works out to about 0.0308% per draw. The 70-pull pity counter only applies to 5★ results, so Iron Moth has no floor of its own and no targeted pull. A duplicate Iron Moth refunds 120 coins at the 4★ rate.
Iron Moth stats and rank
The sheet lists Iron Moth at 106 HP, 124 speed, ×1.47 attack, ×1.08 physical and ×1.47 special, with 60 defense and 110 special defense — 570 base-stat total. On the three-stat percentile this is 85.9 out of 100, which puts Iron Moth at rank 40 of 966 and in tier S. Relative standing explains more than the total here: its strongest slot is special multiplier (98th percentile) and its weakest is defense (35th percentile), so it is a specialist rather than an all-rounder.
Best moves in Iron Moth's pool
At move level 5 the pool is led by Fire Spin at 33.6 damage per 0.30s (164.8 effective DPS, ×1.47 multiplier), then Body Slam at 75.6 damage per 0.71s (114.6 effective DPS, ×1.08 multiplier), then Hyper Beam at 126.2 damage per 1.76s (105.4 effective DPS, ×1.47 multiplier). 9 of its 19 damaging moves scale with the physical multiplier and 10 with the special one, alongside 4 support moves. Its special multiplier is the higher of the two (×1.47 against ×1.08), so special moves convert better. The top option beats the second by 50.2 DPS, which decides slot one and leaves slot two as a judgement call.
Evolution cards for Iron Moth
Its starting move, Ember, evolves into Fire Blast once the move is at level 5 and you hold the Power card, which boosts attack for that run. The permanent menu cannot substitute: only a Power card picked during the run unlocks the evolution. 19 of its 23 moves carry an evolution card, across 6 distinct cards (Vigor, Sprint, Power, Reflexes, Armor and Synthesis). The strongest of them is Fire Spin at 164.8 effective DPS, so that is the one worth holding a card for first.
Iron Moth compared to similar partners
The two closest stat lines in the roster are Volcarona (+2 HP, -4 speed, -0.03 attack, -20 total) and Espeon (-7 HP, +0 speed, -0.05 attack, -45 total). Against Volcarona, Iron Moth is 4 speed faster and Iron Moth hits harder by ×0.03, and the rank gap is 3 places. Every one of those numbers cuts both ways, so the decision is about which stat the run needs, so neither side is a strict upgrade and the move pools have to break the tie.
