Pokémon Weight Gain Stage Lorebook

1. #1Chubby Stage

   Keys: Appetite, Energy, Slight roundness, Minor stat change, Early weight gain, Body type variation, Plump, Softness, Mild overweight, Playful

   Enabled · After character · Order 10 · 100%

   Entry settings

   At the chubby stage, a Pokémon shows a gentle increase in body mass, with a rounder, softer appearance. Most Pokémon retain their full range of movement and skills, though some may experience a slight drop in Speed or Agility stats. For many, this stage is not detrimental and may even be seen as cute or healthy, especially for naturally round species like Snorlax or Swinub. Appetite may increase, and playful or food-seeking behaviors become more common.

2. #2Fat Stage

   Keys: Thicker, Resting, tubby, Body diversity, Early health impact, Noticeable weight, Fat, Stat changes, heft, Increased appetite, plump, Heaviness, hefty, Slower movement, Reduced agility

   Enabled · After character · Order 10 · 100%

   Entry settings

   Pokémon in the fat stage have a visibly thicker body, with more pronounced fat deposits. Movement may become slower, and Speed or Evasion stats can decrease. Some skills that require agility, such as Quick Attack or Double Team, may be less effective. Pokémon may rest more often and show a preference for food. For some species, this stage can offer increased Defense due to extra padding, but at the cost of overall fitness.

3. #3Obese Stage

   Keys: Health risk, Joint strain, Move limitations, Energy conservation, Fat deposits, Significant overweight, Bulky, Low stamina, Ability impact, Altered gait

   Enabled · After character · Order 10 · 100%

   Entry settings

   Obese Pokémon experience a major increase in body mass, with fat deposits affecting their shape and movement. Moves that require speed or jumping, like Bounce or Acrobatics, become difficult. Stamina drops, and Pokémon may tire quickly in battle or during travel. Some abilities, such as Sturdy or Thick Fat, may offer minor compensations, but overall health risks and reduced battle effectiveness become apparent.

4. #4Morbidly Obese Stage

   Keys: Major mobility loss, Severe obesity, Dependency, Lethargy, Move restriction, Mental strain, Fatigue, Quality of life, Chronic health issues, Sagging skin

   Enabled · After character · Order 10 · 100%

   Entry settings

   At this stage, Pokémon struggle with basic movement and may need help from trainers or other Pokémon. Many moves, especially those requiring agility or flight, become unusable. Health issues such as breathing difficulty or joint pain are common. Pokémon may become lethargic, less social, and more food-focused. Quality of life declines, and the Pokémon’s ability to participate in battles or contests is greatly reduced.

5. #5Super Obese Stage

   Keys: Bed rest, Isolation, Respiratory issues, Extreme obesity, Movement loss, Assistance needed, Immobility, Severe health decline, Circulatory problems, Ability suppression

   Enabled · After character · Order 10 · 100%

   Entry settings

   Super obese Pokémon are nearly immobile, often requiring constant care. Most physical moves are impossible, and even some special moves may be affected by the Pokémon’s condition. Abilities that depend on movement, like Run Away or Levitate, are suppressed or lost. Health complications are severe, and the Pokémon’s world shrinks to its immediate surroundings. Social interaction and training become rare.

6. #6Blob Stage

   Keys: Helplessness, Complete dependency, Move incapacity, Total immobility, Extreme fatness, Organ strain, End-stage obesity, Critical health, Loss of function, Soft mass

   Enabled · After character · Order 10 · 100%

   Entry settings

   In the blob-like stage, a Pokémon is almost entirely composed of soft, immobile fat. It cannot move or battle and is fully dependent on others for care. All physical and most special moves are unusable, and abilities are effectively nullified. Health is critically compromised, and the Pokémon’s quality of life is at its lowest. This stage is considered dangerous and unnatural for any species.

7. #7General Effects Across Body Types

   Keys: Body diversity, Species variation, Unique responses, Type advantage, Natural bulk, Evolution, Adaptation

   Enabled · After character · Order 10 · 100%

   Entry settings

   Different Pokémon species and body types respond to weight gain in unique ways. Naturally bulky Pokémon like Snorlax or Hariyama may tolerate higher stages with fewer negative effects, while agile or flying types like Pidgeot or Jolteon suffer more pronounced losses in speed and skill. Some Pokémon may adapt by developing new moves or abilities, but most experience a decline in overall function as weight increases.

8. #8Impact on Skills and Abilities

   Keys: Training, Evolution impact, Contest appeal, Battle performance, Stat changes, Move effectiveness, Ability suppression

   Enabled · After character · Order 10 · 100%

   Entry settings

   Weight gain can reduce the effectiveness of moves that require speed, agility, or flight. Abilities tied to movement or evasion may be suppressed, while those related to defense or bulk may see minor boosts. Training becomes more difficult, and some Pokémon may be unable to evolve or participate in certain activities. Contest appeal may shift, with some judges favoring cuteness or bulk, but overall performance suffers.

9. #9Quality of Life Considerations

   Keys: Social interaction, Happiness, Well-being, Lifestyle, Mental state, Trainer care, Health management, Dependency

   Enabled · After character · Order 10 · 100%

   Entry settings

   As Pokémon progress through the weight gain stages, their quality of life can decline. Social interaction, play, and training become limited, and health issues may cause discomfort or pain. Pokémon may become more dependent on their trainers for care and support. Responsible trainers monitor their Pokémon’s health and happiness, ensuring that weight gain does not compromise their well-being.

10. #10Quadrupeds

    Keys: Resting, Pressure sores, Quadruped, Joint strain, Agility loss, Mobility, Fatigue, Paw pad, Four-legged, Physical limitation

    Enabled · After character · Order 10 · 100%

    Entry settings

    Quadrupedal Pokémon rely on all four limbs for movement and balance. As they gain weight, their mobility and agility are the first to suffer, especially at the "fat" and "obese" stages. Joint strain and paw pad discomfort become common, and their ability to run, jump, or use moves like Quick Attack or Agility is reduced. At "morbidly obese" and beyond, standing for long periods or supporting their own weight becomes difficult, leading to more time spent lying down and a risk of pressure sores.

11. #11Bipeds

    Keys: Two-legged, Crawling, Biped, Physical stress, Leg strain, Upright posture, Back pain, Balance, Agility, Move loss

    Enabled · After character · Order 10 · 100%

    Entry settings

    Bipedal Pokémon experience increased strain on their legs and lower back as they gain weight. At the "obese" stage, balance issues may arise, making it harder to perform kicks, jumps, or acrobatic moves. Moves like High Jump Kick or Close Combat become less effective or even risky. At "super obese," standing upright may be impossible, and these Pokémon may be forced to sit or crawl, losing access to many of their signature moves.

12. #12Serpentine

    Keys: Elongated, Slithering, Flexibility, Movement loss, Sluggishness, Immobility, Body length, Serpentine, Fat distribution

    Enabled · After character · Order 10 · 100%

    Entry settings

    Serpentine Pokémon distribute weight along their entire length, so early stages of weight gain may not hinder them much. However, at "obese" and above, their bodies become less flexible, making moves like Coil or Wrap less effective. Excess fat can also impede their ability to slither quickly or climb, and in extreme cases, they may become sluggish and unable to support their own length, leading to immobility.

13. #13Avian/Flying

    Keys: Wings, Joint damage, Grounded, Flying, Flight loss, Airborne, Avian, Stamina, Agility, Wing strain

    Enabled · After character · Order 10 · 100%

    Entry settings

    Flying Pokémon are highly sensitive to weight gain. Even at the "fat" stage, flight becomes more taxing, and stamina drops. At "obese," many lose the ability to take off or maintain flight, grounding them and making moves like Fly or Brave Bird unusable. At "morbidly obese," wing joints may be damaged from supporting excess weight, and these Pokémon become fully terrestrial.

14. #14Aquatic

    Keys: Aquatic, Water movement, Amphibious, Diving, Land movement, Fatigue, Buoyancy, Speed loss, Swimming, Maneuverability

    Enabled · After character · Order 10 · 100%

    Entry settings

    Aquatic Pokémon can tolerate more weight due to buoyancy, but excessive fat can still slow them down and reduce maneuverability. At "obese," they may struggle to swim against currents or dive deeply. Moves requiring speed, like Aqua Jet, become less effective. For amphibious species, moving on land becomes especially difficult at higher weight stages.

15. #15Amorphous/Blob-like

    Keys: Flexibility, blob, Movement loss, Sluggishness, Transformation, Shape loss, Amorphous, natural blob, Softness

    Enabled · After character · Order 10 · 100%

    Entry settings

    These Pokémon are naturally soft and flexible, so early weight gain has little effect. However, at "super obese" or "blob-like," their mass may become so great that movement is extremely slow or impossible. Ditto, for example, may struggle to transform into more agile forms, and Grimer may find it hard to hold its shape.

16. #16Insectoid/Exoskeletal

    Keys: Exoskeleton, Exoskeleton damage, Mobility loss, Flight loss, Structural stress, Immobility, Armor, Joint pain, Tightness, Insectoid

    Enabled · After character · Order 10 · 100%

    Entry settings

    Insect Pokémon with exoskeletons are not well-suited to carrying extra fat. At the "fat" stage, their armor may become tight or restrictive, and at "obese," movement is hampered, and flight (if applicable) is lost. As weight increases, the exoskeleton can crack or deform under the pressure, leading to pain, vulnerability, and even permanent damage. Joints may be unable to support the extra mass, leading to immobility at higher stages.

17. #17Humanoid

    Keys: Confidence, Humanoid, Social impact, Agility, Move loss, Dexterity, Contest performance, Fine motor skills, Physical limitation

    Enabled · After character · Order 10 · 100%

    Entry settings

    Humanoid Pokémon experience weight gain similarly to bipeds, but with more pronounced effects on dexterity and fine motor skills. At "obese," moves requiring grace or speed, like Psychic or Focus Punch, are less effective. At "morbidly obese," social and mental effects may appear, such as reduced confidence or reluctance to perform in contests.

18. #18Massive/Already Large

    Keys: Organ stress, Heart strain, Massive, Endurance, Health strain, Immobility, Natural bulk, Breathing difficulty, Bulk, Large

    Enabled · After character · Order 10 · 100%

    Entry settings

    These Pokémon are naturally built to carry great mass. Early weight gain has little effect, and even at "obese," they may function normally. However, at "super obese" or "blob-like," even they can become immobile, and health issues like breathing difficulty or heart strain may arise. For Snorlax, the "blob-like" stage is almost a natural state, but for others, it can be dangerous.

19. #19Small/Lightweight

    Keys: Mobility loss, Small, Vulnerability, Health issues, Speed loss, Agility, Prey, Lightweight, Physical limitation

    Enabled · After character · Order 10 · 100%

    Entry settings

    Small Pokémon are quickly affected by weight gain. At the "fat" stage, they may lose their speed advantage, and at "obese," they can become unable to escape predators or use moves like Quick Attack. Their tiny frames are not built for excess weight, so health issues appear sooner than in larger species.

20. #20Floating Bodied

    Keys: energy imbalance, social isolation, altitude loss, dependence, fatigue, quality of life decline, reduced agility, overheating, increased energy use, life-threatening complications, grounding risk, internal stress, levitation strain, immobility

    Enabled · After character · Order 10 · 100%

    Entry settings

    For floating, round-bodied Pokémon, extreme weight gain leads to escalating health and lifestyle consequences. As bodyfat increases, these Pokémon require much more energy to maintain levitation, resulting in frequent fatigue and reduced agility. Overheating and internal energy imbalances become common, and at higher stages, they may struggle to stay airborne or become grounded entirely. This loss of mobility often causes social isolation and dependence on others for care. In the most severe cases, life-threatening complications arise, and the Pokémon’s quality of life is drastically diminished, with total loss of independence and constant discomfort.
