Appearance[]
Amanda is a slim-built, medium-small woman with blue eyes and long brown hair in a ponytail. Despite being 24 years old when she reverts to human form, Amanda looks like a young girl.
When Amanda transforms, she becomes a large, light-green masculine-looking humanoid monster with bright yellow eyes and huge muscles. Her clothes also change, becoming a loincloth with bands around her arms and legs.
Personality[]
In her human form, she is a somewhat snarky and sarcastic individual. but is at heart a good team player who pulls her weight. She is however, very easily peeved by people treating her like a child, due to her being a 24 year old woman in a child's body, and will not hesitate to retaliate against anyone who does so.
In her monster form, she can be a bit more brutal and savage, mercilessly attacking her enemies without hesitation.
Powers and Abilities[]
- Cursed Physiology: As a result of a curse placed on her, Monster Girl possesses the supernatural ability to transform herself from human female to a substantially larger, stronger, and more resilient, humanoid monster form. Her monster form grants her the following abilities.
- Regenerative Healing Factor: When transformed, Monster Girl can easily recover from injury and damage faster.
- Supernatural Durability: Amanda's transformation causes her muscles to become larger, attributing to her superhuman weight. Her body's skin is immune to most forms of conventional injury, including extremes in temperature and pressure, open flame, severe cold, radiation, and concussive forces such as impacts and explosions. It also increases the amount of punishment she can take to an exceptional level.
- Supernatural Strength: Monster Girl possesses a great amount of strength, enabling her to lift in excess of 60 tons. It is conceivable her strength will increase in proportion to her increase in size.
Abilities[]
- Enhanced Combat: Amanda is proficient in close combat when fighting Rex Splode. As Monster Girl, her combat style relies on instinct and sheer brute force, which would be her downfall against Battle Beast who, as well as an immensely powerful being, was also a highly skilled combatant.
Equipment[]

Designed by Robot
- Anti-Reverse Aging belt/Aging Belt: Amanda would initially de-age because her curse caused her to be rebuilt with an incorrect temporal offset when she transformed back into a human. To counter this, Robot designed a special belt that stores a digital copy of certain cells before her transformation. This belt tricks her curse into using those stored cells when she turns back, thus preventing her from de-aging.
Weaknesses[]
Current[]
- Magical Physiology: After she was rushed to the hospital due to her severe injuries, the doctors faced difficulties in providing her with the necessary medical treatment. Because of Monster Girl's unique magical physiology, they were unable to properly diagnose her condition. Her body exhibited characteristics that the medical staff had never encountered before, leaving them unsure of how to treat her.
- Beings of Greater Strength: While supernaturally strong in her monster form, her strength does have its limits as she was not only completely dominated by Battle Beast in their fight, but he aslo very nearly killed her, despite landing three punches beforehand.
Former[]
- Reversed Aging: As part of her curse, when Amanda transformed back into her human form, she initially appeared younger than her actual age of 24. This was due to her curse causing her to be rebuilt with an incorrect temporal offset, giving her the appearance of a young girl. However, this downside was resolved thanks to the efforts of Robot, who designed a special belt. This belt stores a digital copy of certain cells before her transformation. It tricks her curse into using those stored cells when she reverts, preventing her from de-aging when she uses her powers.
