my Super Mario (Specifically Koopaling OCs), the Black Shells :> They're a group of misfits who started off as minions for Bowser, but then were either thrown out or wandered off to fight alone. At first, the Koopalings sneered at them due to their low social status, but after they battle, they see each other as friendly rivals.
All of the characters are anti-heroes to a degree, with some of them borderlining on evil, particularly Dynamo and Cyril. None of them see themselves as 'good' or 'evil'; they tend to pick and choose who to side with, but only when it suits them, e.g. Dynamo would gladly fight against his own kind, shy guys, if it benefited him somehow. All of them are named after magicians.
So, here are the characters, from left to right:

Penn Troopa: Named after Penn Jillette. He's a drill sergeant-type who's good at hand-to-hand combat. The leader of the Black Shells, he tends to shout a lot and give orders. He's usually bossy, but deep down he cares a lot about the team. He's pompous, fiercely loyal, and never takes risks. One day, he'd like to be Bowser's deputy, and lead the koopa army to victory.
Personality-wise, Penn is lawful-evil; he’s a bad guy, and he knows it. But he is evil in what he calls ‘the right way’. He never steals, cheats or lies in any way; he wants to be successful because he’s strong, not because he’s sneaky.
In battle, he’s strong and has lots of hand-to-hand close combat attacks. He prefers to fight with his bare hands; he never uses weapons because he wants to prove how strong he is without the use of them.

Derren Bones: A dry bones named after Derren Brown. He is the oldest member of the group. He can bring dead creatures to rise from their graves and summon armies of them to fight for him. Touching plants also causes them to rot and die. He is fairly weak himself, but he is immortal, although 'killing' him weakens him for long periods of time. He's a bit of a loner and prefers to spend time alone after the last girl he dated died of old age. He's already achieved his first goal of immortality, but he wants to become stronger, and one day find someone to spend his immortal life with.
Derren is cold-blooded and swift. He stays silent while he summons his undead army to fight the enemy, and may even pull his head off just to throw it at someone. It might make him look a little silly, but he is dead serious (no pun intended. Ha). He gets on particularly well with Penn because they’re both rather pompous and have a more serious look on life. Deep down, he enjoys the company of the rest of the Black Shells, but he sees them as rather young and immature.

Dynamo Guy: Named after Dynamo. Despite being a shy guy, he's very outspoken and sarcastic, and is nothing like his species' stereotype. He always has a snarky comment up his sleeve. He's an explosives expert, and creates bombs of various kinds. He isn’t quite sure of his purpose in life, and he doesn’t have one major goal he wants to achieve, but he enjoys causing chaos for the sake of chaos.
Dynamo often uses his machinery to fight for him. It makes him slow, but very powerful. He carries various explosives around with him, despite the fact that most of them are much bigger than him. How? Who knows?

Copperfield Koopa: Named after David Copperfield. He's a tall, lanky Mechakoopa who is often called Copper for short. He was built by Dynamo and brought to life by Cyril’s potions. He is shy and relaxed, and usually goes along with what everyone else tells him. He is very fond of the group, and secretly loves physical contact with people.
Dynamo originally built Copper to be a giant explosive, but he liked him so much he decided to ‘keep’ him as a member of the Black Shells. Copper is acrobatic and can flip over several times, using his legs to kick anyone nearby. As a last-ditch attack, he can throw one of his arms or legs, causing them to explode into flames on impact (luckily he has some spares). He is the weakest of the group, and often goes to help one of the other members rather than fight alone.

Cyril Koopa: An alchemist named after Cyril Takayama. She longs to be the most powerful alchemist in the land, maybe one day even more powerful than Kamek, who she sees as a role model. Her father was a magikoopa, and as she grew up, she wanted to follow in his footsteps.
Cyril is often quiet, but is a perfectionist and gets frustrated easily when things don’t go her way. She can go from calm to irritated in the space of a few seconds. The more stressed out she is, the faster those potions fly. She can go from calm to a fit of panic in the space of a minute. Her potions specialize in various elements – fire potions, ice, lightning etc. – and can also make herself disappear and reappear in random places.

Hammer Jay: A Hammer Bro named after Ricky Jay. He’s goofy, laid-back and a bit of a joker. He became tired of training with other Hammer Bros, and often used to muck around and wind the others up. Eventually, he was kicked out of Bowser’s Hammer Bro troop, causing him to go down his own pathway in life.
Jay tends to play around in battle; he’ll pretend to struggle for a while, and then strike when his opponent falls for it. He’s surprisingly tough; instead of throwing hammers like his fellow species, he attacks with a giant rubber hammer that makes squeaky noises when used. He may even throw ‘confetti’ which is incredibly sharp and will damage his opponent. He may look silly, but he’s strong, and not to be messed with.
Jay is the newest member of the Black Shells. Unlike the others, he has no real goal in life; he just wants to have fun and fool around. Penn finds him exasperating, but he puts up with him because he’s strong, and easily manipulated.


This is just a quick concept piece of the group, so y'all get a basic idea of how they look and act, but I'm definitely gonna draw more of them in the future c; I definitely wanna draw more detailed pieces of each of the group, hopefully in the next few weeks!
