A very mischievous, fun-loving experiment. Being a 0-series experiment, she is part of Jumba's test batch and is mostly a mild nuisance. She was originally designed to soil freshly cleaned things with her ink, like laundry, and is often attracted to blank objects like canvases or walls. Inkstain is known to be playful and not very combative when confronted. She is also highly curious and naive, often following objects of interest or mimicking others. Inkstain is also known to be attracted to food, particularly that of seafood. When needed, she can tuck in her antennae and curl up her tail to vaguely pass herself off as a rabbit.
Strengths/Abilities:
Ink production - Inkstain's most notable trait is the ability to produce an ink-like substance using certain organs in her body. This substance is not easily washable by water. She can spit globs of ink to hit things at a distance, and secrete ink from her pawpads to further cause messes. Inkstain is able to control whether her pawpads secrete ink or not, but is unable to fire inky projectiles from them like she can with her mouth. She also has a cannon-like tail capable of shooting ink at its end, and may use it as a rudimentary firearm by holding it in her hands for better aim.
Wall-crawling - Using her ink-secreting pawpads, she can create a stickier type of ink that allows her to stick to walls and ceilings. This enables her to climb on almost any surface. She will leave a trail as she does this, and cannot climb as well without ink.
Prehensile tail - Her long tail is prehensile, allowing Inkstain to use her tail like a fifth appendage. When needed, she can curl it up to resemble a rabbit's tail.
Vacuum adaptation - Inkstain can survive in the vacuum of space as an inherent ability of being a genetic alien.
Quadrupedalism - She can walk and run on all fours for faster locomotion. This can also be used to make her rabbit disguise more convincing.
Weaknesses:
Water - Inkstain is aquaphobic and unable to swim. In bodies of water, she enters a panic-induced catatonic state and floats helplessly on her back. Her ink can also be dissolved by soaking stained items in water for a while. She also hates getting wet or being bathed. Inkstain is capable of drinking water, but will not enjoy it.
Lemon juice - Lemon juice, or substances derived from it, is capable of quickly dissolving Inkstain's ink and can even burn at her skin. She also cannot drink beverages like lemonade for a similar reason.
Limited ink supply - Inkstain has a limit on how much ink she can use at a given time. If dehydrated, exhausted, or hungry, she cannot produce more ink.
Lack of fighting ability - Inkstain does not have skills primarily designed for combat, and is mostly helpless in a fight. While she can create some level of distraction with her ink and has unskilled fighting moves like biting or punching, she does not possess abilities like super strength, retractable claws, or durability like the later-series experiments. She often opts to flee in battles.
