Nathan Marts
A war criminal, mob boss, and a loan shark that loves to drink uranium waste and do crazy things whenever he can. However, Nathan is genuinely a nice and caring guy who just wants to spread cheer, make friends, and go on stupid adventures.
Oliver The Olive
A snarky, wise, and somewhat egotistical olive who has a passion for science and building whatever his 1,400iq and hyper photographic memory can come up with. Despite this and the fact he always tries to be fancy, he is very simple to get along with and he also just wants to do good, but prefers his own way of doing it.
DotMan
A mythical powerful god made by a crystal that takes over a person and transforms them into a beast that has one objective. Destroy, kill, and irradicate anything it's 16 eyes can see. With his strength, agility, laser-firing, sawing, dot creating, and many more, it will stop at nothing to make sure it's goal of mass destruction is fulfilled.
Turbo Toaster 4000
A giant robotic toaster that leads an army of Talking Toasters and wants to destroy Nathan, Oliver, and Kingworld. With his ability to fire giant pieces of toast, his immense strength, and his power cord as a whip, this giant toaster can maybe cause serious damage if he was a little more smarter and less crazy. (Dav Pilkey parody)
Atlas Adronicus
Atlas is a bloodthirsty greek olive brought back from Ancient Greece by Nathan and Oliver. The bigger difference with Atlas and Oliver is that Atlas has psychic capabilities, but is way less smarter than Oliver. Atlas also wears a powerful hat he stole from Oliver that allows him to summon anything he thinks of. But the bigger the item, the more tired and sleepy he gets. The big problem is he doesn't really plan or make strategies rather than just go straight to attacking and causing as much damage as he can just so he can look like a true warrior and seem threatening.
SohCahToa
A trigonometrical rat that has the biggest ego compared to the rest of the other villains. If he were to strategize the first time, he will not take any other strategies. And if someone were to come up with something better, he will immediately shoot it down and call a new strategy, 'illegal'. But with his powers to shoot death rays that act like hooks, his ability to dilate his size from big to small, and his power to steal an incredible amount of items like people in math problems, Sohcahtoa is one of the more annoying evildoers Nathan and Oliver have to deal with.
Captain Convenience
A confident superhero who tries to look out for Kingworld and fight crime. The problem being, his superpowers are a massive inconvenience to himself. From flying at a max of walking speeds, teleportation with the energy of just walking there, laser vision that melts his eyes, super speed that burns his legs and feet, etc. Thus, although he is jealous of Nathan and Oliver and mad that people constantly make fun of him, he isn't evil. Captain Convenience is just trying to get by with his crummy superpowers.
Sticky The Stickman
Healthy Healthy Healthy Healthy Healthy Healthy Healthy Healthy Healthy Absolutely crazy Healthy Healthy Healthy Healthy Healthy Healthy Healthy Healthy Healthy Possibly immortal Healthy Healthy Healthy Healthy Healthy Healthy If you aren't healthy then his attack will be stealthy.
Princess Pomegranate
The lazy, depressed, and tired princess of Kingworld. Pomegranate is also the one who sends Nathan and Oliver on their quests and missions. Because of some very awful childhood traumas, it has caused her to be the cynical and demanding princess she is. Pomegranate is also really bad at politics and the workload makes her mental state worse. But she keeps the job because she can use her power to get away with anything and scapegoat her childhood. She may also beat the heck out of anyone with her martial arts skills and cartoony anger just by anyone breathing on her wrong. Other than that, she does somewhat care for the people as well as Nathan and Oliver, but is too cynical to show any kind of affection.
Kismet Karmaflux
The arch nemesis of Captain Convenience. Her powers is that if she were to do a good thing, something crazily bad happens, and if she did a bad deed, then the outcome is heavily good. But the thing is, she can't control what fate happens with what she does. For example, if she were to let an old lady cross the street, the old woman would get ran over immediately and maybe vice versa. The biggest reason for becoming Convenience's enemy is because of her split personality disorder. When Captain Convenience failed to rescue her, it caused a head injury, thus giving her an uncontrollable maniacal edge. To this day, she swears that she will one day take down the 'convenient' superhero and get rid of anyone who gets in her way.
Izzy Novaine
One of the more interesting villains Nathan and Oliver have to deal with. This is because Izzy has the power of both hypnotism and telekinesis. The problem is, it's caused by a extremely addictive substance that Izzy has to keep flowing through her at all times via two giant tanks. Failure to do so will cause heavy withdrawals for her. Thus, the substance makes Izzy's speech and movement seem like she's always intoxicated. But, even if her hypnosis is limited and her telekinesis does have a maximum strength, it's enough to help her steal Oliver's inventions to make more of her substance.
The Maker (Bradley)
A version of me. The creator of Nathan and Oliver. With the power to make drawings come to life with his hands, he used that power to make a universe like earth but with more cartoon logic and more zany stories. He also tries to make sure the stories he makes are consistent and make it how it's intended to. The problem is, The Maker isn't quite mentally stable. He's always tired, sleepy, controlling, sarcastic, pessimistic, crazy, and zany. If he were to see his characters try to bring up a plot hole or use convenience, he will shut it down. Even though he likes to take the easy way out of situations. But despite doing things he's not proud of but keeps doing it because it's who he is, The Maker really does want to be a good guy deep down. It's just from him maintaining his creations, his power to abuse cartoon logic and make alive drawings, and the fact he never gets any sleep, it's what makes him more crazy.
