How to Evolve Bonsly

To evolve Bonsly into Sudowoodo, you must level it up while it actively knows the move Mimic. This evolution method bypasses standard level thresholds. A Bonsly caught at level 50 will not evolve until you manually ensure Mimic is in its active four-move slots.

In Generation 9 (Pokémon Scarlet and Violet) and Generation 8 (Sword and Shield, Brilliant Diamond and Shining Pearl), Bonsly learns Mimic exactly at level 16. In Pokémon Legends: Arceus, it learns the move at level 15. In older titles like Generation 4, it does not learn Mimic until level 33.

If your Bonsly is already past the required level and does not know Mimic, you do not need to catch a new one. Simply open the Pokémon's summary screen, navigate to the moves tab, and select "Remember Moves". Re-teach Mimic, then feed Bonsly a Rare Candy or gain enough EXP in battle to level up once.

Once evolved, Sudowoodo earns a harsh 4/10 rating in standard competitive play. It functions strictly as a niche physical breaker under Trick Room conditions. Its base 30 Speed guarantees it will move last in normal gameplay, forcing it to absorb damage before attacking.

Sudowoodo is completely unviable for standard, fast-paced offensive teams. Its pure Rock typing saddles it with five common weaknesses: Water, Grass, Fighting, Ground, and Steel. With a miserable base 65 Special Defense, common special attackers will score an OHKO before Sudowoodo can act.

However, it fits specific Trick Room teams looking for a disposable physical nuke. Players who need a slow attacker to exploit the Rock Head ability will find value here. Rock Head negates recoil damage, allowing Sudowoodo to spam Head Smash—a 150 base power STAB move—without destroying its own HP bar.

To maximize Sudowoodo's limited potential, you must run the Rock Head ability. Sturdy is a competitive trap; surviving one hit at 1 HP is useless when your speed guarantees the opponent will just hit you again the next turn. Rock Head is mandatory to enable the use of Head Smash and Wood Hammer.

The optimal moveset consists of Head Smash, Wood Hammer, Sucker Punch, and Earthquake. Sucker Punch provides crucial +1 priority to snipe weakened, faster targets outside of active Trick Room turns. Wood Hammer handles bulky Water and Ground types that resist Rock.

For EVs, invest 252 points in HP and 252 points in Attack, placing the remaining 4 in Defense. Select a Brave Nature and ensure the Speed IV is exactly 0 to "outspeed" threats inside Trick Room. Equip a Choice Band to maximize wall-breaking power, or a Life Orb if you need the flexibility to switch moves.

Looking at the raw data, Sudowoodo's main advantage is its base 115 Defense. It can comfortably switch into resisted physical hits like Normal or Flying attacks. The combination of Rock Head and Head Smash gives it one of the hardest-hitting Rock-type attacks in the lower competitive tiers, capable of 2HKOing physical walls.

The cons heavily outweigh the pros. Beyond the terrible Speed and Special Defense, Sudowoodo lacks any reliable recovery moves. It cannot use Roost or Recover, meaning chip damage from entry hazards like Spikes and Stealth Rock will permanently wear it down over a match.

Furthermore, pure Rock is an atrocious defensive typing. Unlike Steel or Poison, Rock provides very few useful resistances. As a reminder, Pokedex.me is an unofficial fan-site; competitive viability shifts with tier changes, but Sudowoodo's fundamental stat distribution keeps it permanently locked in PU or ZU tiers.

Players often encounter issues breeding Bonsly for competitive IVs or egg moves. If you place a Sudowoodo in the daycare or picnic without a specific item, it will produce a Sudowoodo egg, not a Bonsly egg. This prevents you from passing down Bonsly-exclusive egg moves early.

To breed a Bonsly, the parent Sudowoodo must hold the Rock Incense. Once hatched, the Bonsly will still need to learn Mimic at level 16 to evolve back into Sudowoodo. This incense breeding mechanic is a holdover from Generation 4 when Bonsly was first introduced as a baby Pokémon.

If you are playing Pokémon Legends: Arceus, the evolution process differs slightly. After Bonsly reaches level 15 and learns Mimic, it will not evolve automatically upon leveling up. You must open your satchel, select Bonsly, and manually trigger the evolution from the menu.
