For one of my series, Spencer, I decided that I'm gonna make more characters for it.

Monstrum Elementary students and teachers:

Clax-An UFO-shaped robot that emits very loud sounds that sounds like they came from a claxon.

Cole-A robot child who's very fast and uses fire magic. He can be very short-tempered. He's good at scaring humans and he's also good at avoid monster catchers due to his speed.

Stingerz-A one-eyed wasp-like robot child who has a sting that causes sleepiness.

Scorp-A scorpion-like robot child who shoots missiles with his tail.

Hideo-A robot child who's another chore boy of the school, alongside Owen (a friend of Spencer who's an ogre child https://www.deviantart.com/germanoman101/art/Owen-the-ogre-1040938767). He's one of Spencer's newest friends. He's good at making plans and is a very kind and optimistic kid.

Norman-A robot child who's Hideo's best friend and one of Spencer's friends. He's a really social person and is curious about many new things. He also wants to be a cop. His uncle is a penitentiary guard.

Brayden-A robot child who's Hideo's and one of Spencer's friends. He's a kid who loves doing gym activities. His uncle is a penitentiary guard who works at the same penitentiary as Norman's uncle. The uncles of Norman and Brayden are also best friends.

Aegis-A friendly robot child and a student of Monstrum Elementary who has the ability to make a sphere-shaped barrier to defend herself. She also uses lasers to attack enemies. She also loves playing with marbles.

Electro-A robot child who's Aegis' cousin. He attacks enemies by shooting electric lasers. He also makes a sphere-shaped barrier, but this one is made of electricity.

Mrs. Victoria-An adult robot who's a math teacher of Monstrum Elementary and also the coordinator of the school.

Mrs. Patchwork-A young adult patchwork doll with the size of a human who's a grammar teacher and another coordinator of the school.

Jenna-A pteranodon-like monster that is able to fly and also uses shadow magic.

Goldie-A golden robot child made of solid gold who's the rich kid of his school. He used to be very arrogant but he decided to change his ways. He attacks enemies by body slamming and punching them, as he's made of solid gold.

Brayden-A brachiosaurus-like monster who's a very peaceful student. His favorite food is seaweed salads.

Other residents:

Mrs. Sapphire-The local babysitter of the capital of Monstrum who's a robot who loves babysitting and taking care of children. She has babysitted many people, especially Spencer and his friends. She has been criticized by Spencer and her friends for being too critical, but they still see that she's really a good babysitter.

Sam-A young adult monopedal snail-like creature who's one of Spencer's friends. Spencer and his friends help him avoid obstacles that are hard for him to avoid.

Terry Mecharex-A robot that looks like a tyrannosaurus. He's the owner of a fast food restaurant.

Firehorn-A prolibytherium-like robot who's able to spit fire and also has fire on his horns. He's a creature that is befriended by Spencer. He was firstly aggressive but Winona (one of Spencer's best friends who's a witch child https://www.deviantart.com/germanoman101/art/Winona-the-witch-1012849160) convinced the robotic animal that everything's gonna be okay and that she and her friends are not trying to hurt him.

The other villains of Monstrum:

Blazellyfish-A jellyfish-like robot with magical powers based on fire. He's one of Captain Coldbeard's henchmen.

Fabrice-A flying robot that is shaped like a falcatus (an extinct cartilagenous fish that lived in North America during the early Carboniferous period) who's one of Captain Coldbeard's henchmen.

King Skylar-The king of the same squid-like alien species as Seamus. (one of Spencer's friends, https://www.deviantart.com/germanoman101/art/Spencer-Seamus-the-alien-1124954932) who's a grumpy king.

Zachary-A zombie robot. He throws shadow bombs and uses shadow magic.

Craig-A robot that shoots small balls and assisted Dr. Daemon (Dr. Daemon is Spencer's archenemy who's a mad scientist https://www.deviantart.com/germanoman101/art/Dr-Daemon-1116621372) on his plans.

Iris-Craig's cousin who's a robot that is able to shoot fire from her cannons and is also capable of flying. She assisted Dr. Daemon on his plans.

Minotaurochs-A minotaur that looks like an aurochs. He scares people by chasing them or using his axe to make sonic waves. He's also good at using wind magic.

Hexa-A young adult robot who's passionate of fashion, magic and trying to conquer the world. She attacks enemies by shooting her hex bullets (which are bullets that transform people into different things) and other magic spells. She mostly uses fire magic.

Two Strong-A very strong robot that can divide into two strong robots. At his original form, he attacks enemies with punches, kicks, electric spheres, lasers and dark magic. He turn into two. The first robot is a floating robot while the other one is a robot with bullets on his neck.

Aquarius-A water-themed robot dragon that has water magic. He's really aggressive and unpredictable.

Gustavo-A former henchman of Dr. Daemon who's a floating globe-shaped robot child who has magical powers. He scares enemies by emitting eerie sounds and using his magical blaster, fire magic and ground magic.

Gil-A tough adult robot with the size of a giant. He can be mean but he actually has a heart of gold. He's the best friend of Gustavo. Spencer and his friends befriended them after they told them that they can be good at something else after they said that they're not good at anything evil. Craig, Iris, Minotaurochs, Hexa, Two Strong, Gustavo and Gil are the ones who redeem themselves and sometimes even befriend the protagonists.

Most of these here are inspired by characters from Blue Dragon (mostly the mecha robos), SamSam and Crashlings but some of them are also inspired by other characters from other series or real life species.
