Obake

Obake is a tall, slender man with pale skin, black hair with red highlights, and blue eyes. When he experiences strong emotions, the left robotic side of his face begins to glow purple.
Obake is intelligent and cool-headed: he almost always anticipates his opponent's moves and has a plan B for every eventuality. Also, if Obake enters into an alliance with someone, it's solely for his own benefit and self-interest.
It was because of the Bob Aken incident that Professor Grenville was against conducting dangerous experiments, and therefore was very worried about Hiro when he began working on the same project.
Although Trina called him her father, respected him, and later continued his work, no special affection was noticed on his part towards her.

Momokase is a tall, slender woman with fair skin, red lips, and green eyes. She has long black hair with blue streaks, which she wears in a ponytail. In her villainous form, she wears a black and blue ninja suit and a blue mask.
Momokase is cunning, intelligent, daring, sarcastic, and determined. She is a master of bladed weapons (knives and katanas) and martial arts. She is quick-tempered, but not impulsive. She is also an excellent chef and loves cooking, but when she dons her mask, she transforms into a professional thief, ready to eliminate anyone who stands in her way.
Momakashi is a mercenary who carries out dangerous missions for more powerful villains. Specifically, she obeys Obaka and carries out his orders. Despite this, she sometimes makes sarcastic remarks or mocks, though this doesn't stop her from following orders.

After his transformation, his entire body was coated in a multitude of chemicals, giving him the form of a purple, slimy humanoid, with limbs still visible. Neurotransmitter lenses attached to his head replaced his eyes, turning them into glowing lime-green spheres. Occasionally, the neurotransmitter can be seen through the slime, and then its lights glow blue. In addition to his standard spherical form, he can transform into other materials and change his shape (for example, becoming a block of stone), but his eyes remain the same. However, he retains normal bodily functions, such as digestion and the ability to feel pain. Initially, his form was unstable, causing him to easily disintegrate if he wasn't careful or stick to other objects due to his stickiness. Through his alliance with Obake, Globby unlocked his potential and learned to control all of his abilities, allowing him to use them to their full potential without error.
Gu Physiology: After a powerful chemical reaction, Dibs' body transformed into a mass of various chemical compounds, causing his body to become extremely gelatinous. He can throw sticky globs to immobilize opponents. The downside of this state is that he still feels pain, and sometimes, if hit too hard, he shatters into pieces.
Elasticity: He can change shape by extending or contracting his arms and legs. This makes him highly agile: he can stretch to cover long distances or compress himself into a ball to bounce off obstacles. His elasticity makes him very difficult to physically destroy.
Shapeshifting: Thanks to his elasticity, he can assume not only a humanoid form but also other shapes, such as a bull-like creature or a spring. By fusing with a neurotransmitter, Gobby can command his cells to transform into any substance or material.

Noodle Burger Boy was the former robotic mascot of the Noodle Burger restaurant until he was hacked by Obake and became his servant. Noodle Burger Boy was programmed with a positive and cheerful attitude, always happy to serve customers and make them smile. He was also given a predictive algorithm that allowed him to better serve customers and predict what they would request if they frequented the restaurant.
When Obake hacked him, Noodle Burger Boy still maintained the same attitude, but added a "killer" factor, gleefully telling his opponents they'd been beaten or attempting to kill them while remaining happy. Only when he reported his failure to Obake did the robot become afraid.
He also constantly uses restaurant terms, which can become irritating to those who interact with him regularly, such as Sticky.
He has some childish tendencies, annoying Obake by asking him excessively nosy questions and giggling childishly when Momakase tells Sticky that his breath smells like trash.
Because he was originally a military robot, he was already capable of various combat moves and was equipped with various tools and weapons, but many of his upgrades as a restaurant mascot can also be used for attack. He possesses superhuman strength and high maneuverability.
At some point, he also started calling Obake his father (or dad), calling Trina "Big Sister", while Trina also called him "Little Brother".

She is an android created by the villain Obake, whom she calls "father".
In her human form, Trina appears to be a teenager: she has fair skin, long brown hair, and light blue eyes, matching Obake's. She wears a purple hat, a pink short-sleeved shirt, gray jeans with stars, black fingerless gloves, and white shoes. However, robotic parts are visible beneath her "skin."
Trina has a complex personality: she's sarcastic, impatient, and rebellious. Although she's devoted to Obaka, she often acts independently. She's intelligent and manipulative.
