How to unlock Krookodile
There is no direct purchase for Krookodile. It appears on the Unova banner inside the 4★ pool. The 4★ band takes 6.5% of all pulls and holds 211 partners, so one specific Krookodile works out to about 0.0308% per draw. The 70-pull pity counter only applies to 5★ results, so Krookodile has no floor of its own and no targeted pull. A duplicate Krookodile refunds 120 coins at the 4★ rate.
Krookodile stats and rank
The sheet lists Krookodile at 113 HP, 117 speed, ×1.34 attack, ×1.34 physical and ×1.06 special, with 80 defense and 70 special defense — 519 base-stat total. On the three-stat percentile this is 81.5 out of 100, which puts Krookodile at rank 64 of 966 and in tier S. Relative standing explains more than the total here: its strongest slot is physical multiplier (88th percentile) and its weakest is special multiplier (49th percentile), so it is a specialist rather than an all-rounder.
Best moves in Krookodile's pool
At move level 5 the pool is led by Body Slam at 75.6 damage per 0.71s (142.2 effective DPS, ×1.34 multiplier), then Bite at 35.7 damage per 0.34s (141.7 effective DPS, ×1.34 multiplier), then Tackle at 33.6 damage per 0.38s (120.1 effective DPS, ×1.34 multiplier). 13 of its 18 damaging moves scale with the physical multiplier and 5 with the special one, alongside 4 support moves. Its physical multiplier is the higher of the two (×1.34 against ×1.06), so physical moves convert better. The top option beats the second by 0.4 DPS, which decides slot one and leaves slot two as a judgement call.
Evolution cards for Krookodile
Its starting move, Mud Shot, evolves into Earth Power once the move is at level 5 and you hold the Power card, which boosts attack for that run. A level 5 move without Power in the run is still just a level 5 move. 18 of its 22 moves carry an evolution card, across 6 distinct cards (Vigor, Sprint, Power, Reflexes, Armor and Synthesis). The strongest of them is Body Slam at 142.2 effective DPS, so that is the one worth holding a card for first.
Krookodile compared to similar partners
The two closest stat lines in the roster are Rillaboom (+2 HP, -3 speed, +0.05 attack, +11 total) and Unfezant (-7 HP, +0 speed, -0.01 attack, -31 total). Against Rillaboom, Krookodile is 3 speed faster and Rillaboom hits harder by ×0.05, and the rank gap is 2 places. The exchange rate is the point: nothing here improves on both lines at once, so neither side is a strict upgrade and the move pools have to break the tie.
