To evolve your partner in Digimon World Re:Digitize for the PSP, you must meet specific stat thresholds, weight requirements, and care standards within a set timeframe. Core Evolution Mechanics
Evolutions are governed by several key factors that must be balanced before your Digimon reaches its "deadline" age:
Stats: Minimum values for HP, MP, Attack, Defense, Speed, and Brains are required for most Champion, Ultimate, and Mega forms.
Weight: Each Digimon has a target weight (e.g., WarGreymon requires 70g). You gain a "quota" point if your Digimon is within the required weight range.
Care Mistakes (CM): These occur when you fail to feed, rest, or take your Digimon to the bathroom. Some evolutions require 0 CM, while others (like "filth" Digimon) may require many. Care Mistakes carry over through a Digimon's life until it dies and reincarnates.
Quota: This is the number of criteria (Stats, Weight, Care Mistakes, Battles/Techs) you must successfully meet to trigger the evolution.
Techniques & Battles: Some advanced forms require a minimum number of battles won or a specific number of techniques learned. Evolution Phases & Lifespan
Digimon typically evolve at specific ages, though this can be triggered early by meeting all requirements and interacting with your partner (e.g., praising or scolding). Typical Duration/Age Requirements Fresh No branching paths; no influence needed. In-Training No minimum stats; determined by the highest "focus" stat. Rookie 1–3 days First stage requiring specific stat training. Champion 4–7 days Requires meeting a specific quota of stats and care. Ultimate 7–11 days High stat requirements; lifespan begins to dwindle. Mega 11–15 days Final form; usually dies around age 14 or 15. Helpful Resources
Digimon World Re:Digitize for the PSP, the evolution system returns to the classic "pet-simulator" roots of the original PS1 game, requiring careful management of stats, weight, and care mistakes. Core Evolution Mechanics
Evolution is determined by several interlocking variables. If you fail to meet any prerequisites within the designated time, your Digimon will die: Stat Quotas
: Each Digimon has a set of required stats (HP, MP, Attack, Defense, Speed, and Brains). Most forms have a "Quota"—a specific number of these requirements (e.g., 5 out of 7) that must be met to trigger the evolution. Weight & Care Mistakes
: Your Digimon's weight and the number of "Care Mistakes" (accidents, skipping sleep, or overfeeding) are critical. Some evolutions require keeping mistakes below a certain threshold. Bonus Requirements : Certain powerful forms, such as WarGreymon
, are "locked" behind story events or coliseum battles and cannot be obtained until unlocked. Lifespan & Deadlines
: Each evolution phase has a "DEADline." For example, even if you use an evolution item to reach a Mega form early, the Digimon will still likely die on its 14th or 15th day unless its lifespan is specifically extended. Pros and Cons of the System Reviewers from sites like Dragon Quill highlight significant shifts from previous titles:
Don’t stress the first generation. Your first Digimon will probably become Numemon or something average. That’s fine—each death gives you a stronger egg. Focus on learning the timing of calls and unlocking more of the map. digimon world re digitize evolution guide psp
If you’re aiming for a specific Mega, look up a dedicated evolution tree online. The PSP version’s requirements are slightly different from the 3DS remake (Re:Digitize Decode), so make sure you’re using a PSP guide.
Happy raising, Tamer! Now go clean up that poop before your Agumon turns into something embarrassing.

Digimon World Re:Digitize for the PSP, evolution (Digivolution) is a pet-sim mechanic where your partner progresses through life stages—Baby I, Baby II, Rookie, Champion, Ultimate, and Mega—based on how you raise them. Unlike traditional RPGs, your Digimon will eventually die and be reborn, requiring you to train multiple generations to reach higher forms. 1. Key Evolution Requirements
To trigger an evolution once the hidden "evolution timer" expires, your Digimon must meet a specific set of requirements known as the Quota. You do not need to hit every single stat; you only need to satisfy the number of conditions specified by the quota for that Digimon.
Stats: These include HP, MP, Attack, Defense, Speed, and Brains. For some evolutions, stats are paired; you may need to meet both stats in a pair to count toward one quota point.
Weight: Your Digimon must be within a certain weight range (in grams).
Care Mistakes (CM): Neglecting your Digimon (e.g., let it poop on the ground, failing to feed it for 90 minutes, or skipping sleep) counts as a care mistake. Some forms require zero mistakes, while others (like Numemon) require many.
Bonus Criteria: These can include a minimum number of battles, high/low Happiness, or high/low Discipline.
Quota: If a Digimon has 7 possible requirements and a quota of 5, you only need to meet any 5 of those criteria to evolve into it. 2. Evolution Stages & Timing
Evolution happens automatically after a certain amount of in-game time has passed in a specific stage. Rookie to Champion: Typically occurs after ~3 days. Champion to Ultimate: Typically occurs after ~4 days. Ultimate to Mega: Typically occurs after ~5 days.
Failure: If you do not meet any specific requirements by the time the timer runs out, your Rookie will turn into Numemon. 3. Training & Gym Tips

Evolution checks occur once your Digimon's evolution timer reaches zero. To trigger a specific evolution, you must meet its
, which is the minimum number of fulfilled requirements from its listed criteria. Quota Requirements by Stage Champion (Adult) : All stat requirements (HP, MP, ATK, etc.) are grouped as one single quota point . You must meet listed stats to earn it. Ultimate (Perfect)
: Stats are grouped into pairs (HP/MP, ATK/DEF, SPD/BRN). Each pair where both requirements are met earns one quota point Mega (Ultimate) : Every individual stat that meets its requirement earns one quota point Key Evolution Factors Care Mistakes (CM)
: Earned by pooping on the ground, missing a 90-minute feeding window, or missing a 90-minute sleep window. These carry over through evolutions until the Digimon dies.
: You must be above (+) or below (-) a specific weight target. Note that higher weight can slow down response time in battle. Bonus Quotas : Requirements like Battles Won Happiness (Hpn) Discipline (Dsc) Techniques Learned
often count as individual quota points to help you reach the needed total. Priority System
: If you meet the Quota for multiple Digimon, the game uses a hidden priority list (often the "middle branch" on the evolution chart is top priority). Example Evolution Requirements Key Requirements 1000 HP, 70 ATK, 60 BRN, 26+ Weight, ≤3 Mistakes 80 DEF, 90 BRN, 24+ Weight, ≤5 Mistakes
2900 HP, 230 ATK, 220 DEF, 160 BRN, 53+ Weight, ≤3 Mistakes Megakabuterimon 12000+ HP/MP, 1500+ ATK, Weight 79g, 2 CM Evolution Timelines (Approximate) Evolution Timer ~41.5 hours ~86.5 hours

Direct Answer To evolve your Digimon in Digimon World Re:Digitize
for the PSP, you must meet a specific Quota of requirements before the evolution timer hits zero. The Core Evolution Requirements
Evolution in this game is not just about gaining levels. You must balance several parameters to hit your target Digimon's required quota:
Stats: Your Digimon must equal or exceed specific requirements across HP, MP, Attack, Defense, Speed, and Brains. Final Advice Don’t stress the first generation
Care Mistakes (CM): Failing to feed your hungry Digimon within 90 minutes, not letting it sleep within 90 minutes of being tired, or letting it poop on the floor creates a Care Mistake.
Weight: Your Digimon must either be over or under a very specific target weight.
Happiness & Discipline: Maintained as percentages. Some evolutions require keeping these above or below specific thresholds (e.g., 80%+).
Battles: The number of successful wild battles your Digimon has won (Coliseum battles do not count towards this).
Techs: The total number of techniques you have permanently unlocked on your tamer profile.
Decode Level: The overall level of your Tamer's progression. How the Quota System Works
Each evolution stage has a different formula for how stats are counted toward your goal quota: 1. Champion Stage
You must meet all listed stat requirements to get exactly 1 point towards your quota.
If a target Champion needs 1000 HP, 80 ATK, and 80 DEF, having 80 ATK and 80 DEF but only 800 HP awards you 0 stat quotas. 2. Ultimate Stage Stats are grouped into pairs: HP/MP, ATK/DEF, and SPD/BRN.
Meeting both stats in a listed pair gives you 1 quota point. If only one stat of a pair is required, fulfilling that one stat alone awards you the point. 3. Mega Stage
This stage is highly strict. You earn exactly 1 quota point for every single individual stat requirement you successfully hit. ⚠️ Critical Rules to Remember
Care Mistakes Carry Over: Any Care Mistake you trigger as a Baby or Rookie will carry over to its Champion and Ultimate forms. They only reset when your Digimon dies. Keep this in mind when aiming for Megas that require exactly 0 Care Mistakes!
The Priority System: If you fulfill the requirements for multiple branching evolutions at the exact same time, the game will default to a hardcoded priority list. To get lower-priority monsters, you must actively sabotage your stats or manipulate your weight/CMs to fail the requirements of the higher-priority monsters on that branch.
