I imagined prequel for Paleofriends and prequel episodes for Spencer.
The prequel for Paleofriends is called Bassim and is set way before the events of Paleofriends. It is about Bassim's childhood and it's set in the Second Desert, Bassim's home and one of the areas of the biggest island of the prehistoric archipelago, which like the Triassic desert, it is characterized as a desert, but instead of Triassic animals, there's animals from the Cenozoic and Holocene of the Middle East, South Asia, Central Asia and North Africa. It is gonna be based mostly on Middle Eastern folk tales such as those One Thousand and One Nights but also having some other Paleofriends aspects such as the presence of dinosaurs and other prehistoric animals since the world of Paleofriends has all extinct animals. During this time, Bassim and his friends were 7 years old, even younger then Starla, who's a teenager. In Paleofriends they're on their 40s.
The prequel episodes of Spencer on the other hand are about the friend of Hexa, Catherine, a cookies and cream (a variety of ice cream) mage who's a very good sorceress and one of Spencer's enemies until she redeemed herself just like Hexa. Before she became a villainess, she was unfortunately another person that Officer Bailey, the same officer who falsely arrested the mother of one of Spencer's friends because she didn't allow them enter their house cause they had no warrant to enter the house. Catherine was arrested for just punching a thief and defending herself from said thief. She was sentenced to 7 months in prison. After she unfairly wasted her time in prison, she was released and felt like she did have a new purpose. She became a villainess since the world was unfair to her. One of her goals as a villainess is to defeat other villains. She didn't defeat Bailey to avoid imprisonment but she felt free to defeat the other villains of the villain headquarter. During that time, they had a very evil and dangerous plan and so Catherine decided to defeat them since no one cared about what these people were up to.
Here are most of the characters that originate from these prequels.
Starting with Bassim. Bassim is gonna have characters that I already drew on DA or upcoming characters that I already mentioned here and on DA, which include Bassim himself and other residents of the Second Desert such as Samir, Sabino, Ayoub, Omar, Aisha, Sahar, Ahmed, the hyraxes and etc. But there are more characters who reside this desert and other characters that Bassim met during his childhood and some friends that he currently has:
Syed-A Syrian elephant (an Asian elephant subspecies that became extinct due to human activity) who's a courageous retired warrior. He taught Bassim and his friends on how to be courageous and how to confront and solve many things. His favorite weapon is his spear and sometimes he uses a sword. He's 79 in Paleofriends.
Sami-A Syrian camel (an extinct camel that lived in Syria) who's one of Bassim's friends. He's very peaceful and but he will not hesitate and attack foes in order to defend himself and his friends. He attacks enemies via kicking and falling foes whenever they try to get on his back, like camels do.
Amir-An africtis (an extinct carnivoramorph that lived in Libya) who's another friend of Bassim.
Boualem-A barbary lion who's another friend of Bassim and also a childhood friend of Ayoub since preschool. He's a courageous, friendly but sometimes stubborn person but nonetheless a fun guy to be around.
Daamin-A Syrian wild donkey (an extinct subspecies of donkey that lived in Syria) who's another friend of Bassim. He's not that smart but he's good at attacking enemies. He mostly attacks them via kicking them.
Ekram-An eritherium (an extinct pachyderm that lived in Morocco) who's one of Bassim's friends. He's mostly a jolly and optimistic individual.
Soheir-Sahar's older cousin who's a vampyrictis (a barbourofelid that lived in Tunisia during the Miocene period) who unlike her syrtosmilus cousin, she's greedy. The families of Bassim and most of his friends are all peaceful and friendly. Ahmed's being the nicest but unfortunately, Sahar and Samir's cousins are not great since they're arrogant and greedy bullies. In Paleofriends, the remorseless feline became one of Sultan Thueban's servants to get more attention and cause she likes evil. She's inspired by Sekhmet, the ancient Egyptian goddess of war.
Asif-An aegyptopithecus (an extinct primate that lived in Egypt during the Oligocene period) who's Samir's cousin, who unlike him, is an arrogant and greedy person. In the prequel, he's just a mean bully. In Paleofriends, he became worse since he decided to become a servant of Thueban since it's a job for "cool" people like him. He's inspired by Babi, the ancient Egyptian god of the Underworld. Although he's not as worse as Safwan, he and Soheir are still evil.
Rabi-A prolibytherium (an extinct giraffid that lived in North Africa and Pakistan during the middle Miocene period) who's a friend of Soheir and Asif.
Aadam-A diacodexis (an extinct herbivorous mammal) who's one of Bassim's friends. He's mostly shy.
Pamir-A pakicetus (an extinct cetacean that lived in Pakistan during the Eocene period)
The Monster Anchovy-A monosmilus (an extinct anchovy that lived in Pakistan during the middle Eocene period) that is called that name due to his monstrous appearance. He's very aggressive and he has sharp teeth similar to a smilodon.
Tabaarak-A thalassictis (an extinct hyena that lived in Europe, Asia and North Africa during the late Miocene) who's a thief and he has other 39 hyenas as his allies and a vulture as an additional ally. He laughs at the misfortunes of other people and also lives in a hideout. It is also worth mentioning that one of the thieves also decided to redeem himself since it wasn't the best job for him. He and his thieves are also excellent swimmers. He and his allies are inspired by the 40 thieves from Ali Baba and the 40 thieves. His design is gonna be inspired by the striped hyena, a hyena species found in North and East Africa, Central Asia, the Indian subcontinent and the Middle East which is also known as the national animal of Lebanon.
Alfred-An aegypius prepyrenaicus (an extinct vulture that lived in Spain and possibly even in Gibraltar during the middle Pleistocene period). The former additional ally of the 40 thieves of the Second Desert. He used to be one of Bassim's enemies. He redeemed himself after Bassim tried to convince him. He gave up on being a thief and he became a better person. In Paleofriends, he's in his 80s.
Mr. Ghanem-An elderly goliathia (an extinct shoebill who lived in Egypt during the Oligocene period) who's the teacher of Bassim. He's a very friendly individual who wants to see his students succeed in life.
Officer Hashim-An arsionitherium (an extinct paenungulate that lived in North Africa during the late Eocene and early Oligocene) who's a cop of the Second Desert. He's good at catching thieves as he charges at them. Despite he looks grumpy, he's actually nice. In Paleofriends, he retired and someone took his place.
Amina-A hipparion (an extinct three-toed equine that lived in North America, Europe, Africa and Asia during the middle Miocene period until the middle Pleistocene period) who lives in the Second Desert. She's inspired by Bella from The Enchanted Horse.
Salah-A Saudi gazelle (an extinct gazelle species that lived in the Arabian peninsula) who's a friend of Bassim. He's curious about many things in the world. And he mostly encourages Bassim to go to certain places. He was the one who came with the idea of going to certain islands.
Qabilah-A Queen of Sheba gazelle (an extinct gazelle species that lived in Yemen) who's Salah's cousin. She's very peaceful like her cousin. She became a cop in Paleofriends and she's competent at her job.
Asan-An aktautitan (an extinct brontothere that lived in Kazakhstan during the Eocene period) who's the neighbor of Bassim.
Bassim also was in the Jurassic Jungles and the other smaller islands when he was younger and he befriended some people that appeared in Paleofriends. He met Giorgio and his friends, who became Starla's friends in Paleofriends and Giorgio is this guy https://www.deviantart.com/germanoman101/art/Paleofriends-Giorgio-the-garganornis-1115805966. He also became friends with the monkey trio, Jack, Pabel and Irvin, and their friends, which include mostly animals from the Caribbean. Then they met other creatures based on other animals from around the world. But a new character that doesn't appear in Paleofriends, is a pachyrhinosaurus, a microceratus and an eremotherium and also some
Pace-A peaceful pachyrhinosaurus who lives in the Jurassic Jungles.
Erin-A friendly but sometimes lazy eremotherium who lives in the Cenozoic steppes and is friends with Pace. She loves most of the times take a nap but she knows when not to be lazy.
Micah-A microceratus (a ceratopsian that lived in Mongolia during the late Cretaceous period) who's a grumpy but still nice person. He takes many things seriously, even jokes, but he knows how to behave.
Peyton-A pezosiren (also known as the land manatee, is an extinct manatee that lived in Jamaica during the early Eocene period) who's an optimistic individual.
Princeton-A prorastomus (another extinct manatee species that lived in Jamaica during the early Eocene period) who's a very friendly individual. He loves music and to make new friends.
Captain Dorian-A Dominican macaw (a possibly extinct macaw that lived in Dominica) who's a friendly pirate. He's in search of amazing treasures. His crew includes other extinct parrot species from around the world, which include an Aruba amazon, a Martinique amazon, a Cebu hanging parrot, a Martinique macaw, a Cuban macaw, a St. Croix macaw and a Puerto Rican parakeet.
Benjamin-A Bermuda heron (an extinct heron that lived in Bermuda) who's mostly a lazy person as he loves to sleep most of the time.
Sally-A Semper's warbler (a bird species that lived in Saint Lucia that is possibly extinct) who despite seems like a nice person, she's not. She's one of Peyton's enemies and makes fun of him.
Sarge-A St. Kitts bullfinch (an extinct bird species that lived in Saint Kitts and Nevis) who's a grumpy person and a friend of Sally.
Vernon-A Virgin islands screech owl (a possibly extinct owl species that lived in the Virgin Islands) who mostly loves bullying and pranking people via hiding and screeching. He's also friend of Sally.
Calista-A Cyprus dipper (an extinct bird species that lived in Cyprus) who's one of the friends of Giorgio. She loves to sing most of the time and tries to cheer people up.
Kunzang-A peaceful northern Sumatran rhinoceros (an extinct species of rhino that lived in India, Bhutan, Bangladesh and Myanmar) who lives in mountainous forests. He taught Bassim about martial arts and also how to be patient.
King Ananda-A Schomburgk's deer (an extinct deer species that lived in Thailand) who's friends with Kunzang. All of Bassim's new friends were also children in this prequel and in Paleofriends, they're adults and they're in their 40s.
Now the Spencer prequel episodes:
Catherine-A 24-year-old cookies and cream ice cream that before moving to Monstrum, she was falsely arrested by Officer Bailey because she defended herself from a thief. Like I said before, she got sentenced to 7 months in prison and got released but felt like she got a new purpose, to become a villainess, and one of her jobs is to defeat other villains. She's inspired by the White Mage from Mario Hoops.
Ruby Goose-A red mutant goose that creates fire with her wings.
Emerald Crow-A green mutant crow that creates tornadoes with his wings.
Sapphirat-A blue mutant rat that spits sapphire poison.
Antethyst-A purple mutant ant that spits poison. All these mutants have magical power, have their elemental weakness and all of them thankfully got defeated.

Frost-A polar bear plush that is an aggressive and ravaging being.
Calvin-A purple mutant cyborg alien that uses guns and lasers to attack enemies. He additionally has ground magic.
Sir Pandemonium-A yellow demon who tries to make misfortune. He has magic that causes enemies to become unlucky in everything. Catherine defeated him via punching him to the point that he flew away.

Psychic Bee-Mutant bees that were mutated by Jimson. Their sting is poisonous.
Mecha Brugmansia-A robotic vase with brugmansia flowers. He's both a robot and a magical creature. Instead of shooting laser beams, he spits poison. Catherine defeated him with her powerful magic and he got destroyed, allowing her to get a key. Inspired by the bucket from Bad Ice Cream. He got destroyed by Catherine via wind magic which caused him to be pushed by the wind. He was made by Jimson.

Hallucinogenic Honey and Psychic Bee-A mutant anthropomorphic honey that spits poison. Their poison is equal to Jimson, Brody and Mecha Brugmansia. And in fact, he was created by Jimson himself who's expert in creating mutants and machines. He created these with the collaboration of another colleague of his. Catherine attacked him wind magic as she pushed him a lot to the point that he got destroyed.
Shadow Apple-An apple who's a half-demon. He's the final enemy that Catherine encounters and defeats him with his elemental weakness, light magic. He was the hardest foe to defeat as he had incredible magic power.
These are the ones for now. Yeah, these are the prequel OCs as I call them. Well, except most that return in Spencer and Paleofriends.
