Originally, the show Jimmy Two-Shoes was intended to be targeted at a more mature audience. Its initial conception centered around the idea of Jimmy, a well-mannered, do-gooder kid who died in an accident, and was sent to Hell.
Little is known about what the show would do with this concept other than provide mature comedy. The main sources of information for the initial premise are from concept art, rumors, and staff claims. The details herein are ones which attempt to focus on critically analyzing the concept art, and the comments of those who worked on the show.
Exactly how Jimmy met his end is unknown -- but it's often believed that Jimmy was run over by a bus. Regardless how he died, the decision of his after life was accidentally chosen to be Hell. As Hell is often depicted as a place of eternal damnation for very bad people, Jimmy, being an overly optimistic and innocent young boy, would be very out of place. Specifically, Jimmy would seem to be the only good and happy person in the underworlds' population.
From early concept art, it was postulated that such denizens would likely consist of:
Pirates & Vikings
Sock Burglars & Bandits
Crusaders from the holy wars
Evil / Mad Scientists & Monsters
Corrupt Business Men / Wealthy Capitalists
Serial Killers
Even perhaps the inclusion of famous ones (Ex. The clown [bottom] could depict John Wayne Gacy)
Famous horrors from horror movies (Ex. Jason from "Friday the 13th")
Fascist Dictators (Ex. Hitler)
And hellish creatures such as Demons and Imps
For Jimmy, Hell is a fresh and new place to explore and enjoy. Much like the premise of the current show, Jimmy makes it his mission to put a smile on everyone's face, despite how almost the entire population is made of evil people.
One of his main method's of doing so is exploiting the fact that he, like the rest of the people in hell, are 'undead'. Meaning any and all damage sustained by the cast would only inflict pain, including those which would be fatal. Should a character 'die', from their injuries, they would be brought back to life in hell. Jimmy uses this gimmick to entertain himself, and others by hurting / exploiting injuries on his body in amusing ways.
Main Characters
Jimmy
Personality wise, Jimmy seems largely unchanged from his early concept, and his depiction in the aired show. There are a few noticeable differences, but most of which consist of the changes in Jimmy's attire, other than his 'undead' ability. Concept art and model sheets depict Jimmy wearing a light gray dress shirt, a dark gray bow-tie, brown slacks and pointy dress shoes. Additionally, no detail is present in Jimmy's ears.
Lucifer (Lucy)
Jimmy would often be seen as a nuisance to Hell's ruler: Lucifer (nicknamed 'Lucy'). As to his design, Lucy makes the underworld a place of eternal suffering and misery; those who were sent to Hell, were determined to deserve punishment for their sins.
This behavior is similar to his depiction in the aired show: ruler of Miseryville, and CEO of Misery Inc - distributor of horrible and nasty products to make the population miserable.
Heloise
To combat Jimmy's overwhelming positive nature, Lucy instructs Heloise, the spirit of a serial killer and Jimmy's neighbour, to torture him. Even with her horrible, endless attempts to make him miserable, Heloise wouldn't stop Jimmy from making fun of every situation he was thrown in. Eventually, Heloise would develop a crush on Jimmy, and often switch between loving and torturing him.
This behavior is also similar to her depiction in the aired show, discounting her origin as a serial killer, and adding her hyper intelligence and her position at Misery Inc.
Beezy
Due to a lack of early concept art, model sheet, or comment by a creator, it is commonly believed Beezy was not a planned character during this stage in the show's development. But recently, a single image of Beezy has popped up, depicting him drinking gasoline with a frozen Jimmy alongside him (see gallery). His shorts are patterned differently, but otherwise, it appears he is not much different from the final product.
Plot
There is no knowledge of any story that was planned to structure the series. It's existence is possible, but it's likely the current show reflects what early episodes were planned to be: Miscellaneous adventures featuring graphic humour, with possible satire.
Animation Tests
There are a few animation tests known to exist that demonstrated the idea of the show with its early concepts. The videos of these tests have never been released, but there are three known screenshots that likely belong to the demo reels.
According to Edward Kay, co-creator of Jimmy Two Shoes, and Phil Postma, original designer for the concept, the pilot was actually a six-minute non-for-air demo made and paid for by one of the investors. Originally made as an exclusive Teletoon production for the studios' tween demographic at the time, the hell references and other mature elements were removed and aged down once the U.S. broadcasters for Disney XD came on board, as they we're aiming for a more conservative market. The designs we're also altered as the producers didn't like them. Although it is speculated that Charlie Schlatter was the voice of Jimmy, and Jessica DiCicco the voice of Heloise, Kay confirmed Cory Doran indeed voiced Jimmy in the demo.
Changes
Through very few known images, the gradual change from the early concept themes to the final concept can be seen. Early promotional images and character shots show Jimmy and Beezy wearing their finalized attire, with early designs of other characters, like Lucius and Heloise.
Most of these pictures are very small changes to the look of other characters, and they neither fully confirm nor disconfirm the possibility that the show changed from the mature themes.
Possibly a early design of Saffi or some other demon. (read last pic on what it says about these 5 pictures)
"The rest of these designs were once again done just for fun and to get a feel for the show. None of these designs were used in the production of "Jimmy Two-Shoes".
Humans,again,meant to get a feel for the show. (Fun fact: Edward Kay never knew about these images of concept Jez,saffi,the humans and etc. here in this section of the wikia,til now. On Jan.13,2019 7:20-30 A.M. Unknown due to Facebook not giving an exact time,say,the next 10 minutes or so,when they respond.)
(Most of the images here on out,not meant to be used,I know sucks.) Bride of Frankenstein,Wolfman and Frankensteins monster. (Yes,I'm using the correct name of "Franky" here,bad habit of a purist.) (Fun fact: In the "Areas" section of the wikia,in Heloises room,lies a hanging picture of Bride on the wall,it was either supposed to say,she was a fan of monster movies or maybe was a fan of bride in Hell. It probably would've (or not) confirmed her presence in the series.)
An office worker or boss-like demon of a corporate building. (Would be interesting if his design "would've" been used for the 2006 version of the show.) and an Executioner,who most likely has a position performing certain or only one activity when torturing the denizens of Hell. (Maybe one of 3 or so activities and punishments seen below in the Other section.)
A skeleton man,whether human or demon,who knows? Alongside a cobra in a suit,could be representative of a gambler or some other sleazy character,an octopus in a suit and hat,who looks like has som ething to say,probably a living punching bag around the office,and a uni-horned happy looking demon,with a heart on his tie,probably for some creepy and uneasy purpose. (Unless he just loves his job.)
Human,sinister looking clown as seen above in the "Initial Premise" section. Alongside a big,muscular/fat,albiet strong looking demon with a single horn on his head,with horns sticking out of his back.
Scientist,with very tiny spectacles,either human or demon,with a hook for a hand,alongside a big one-horned,red demon with a "erah" or "mmph" mug,an earpiece,and hair covering his eyes. The scientist could possibly be human,but,has green skin to give off an evil scientist vibe. As seen above,once again, in the "Initial Premise" section.
Creature of the Black Lagoon,with a horizontally,severed by the waist,one-eyed,zombie. He has an exposed skull-cap,missing a bottom jaw,and moving,only by his own two hands,dragging his intestines while his organs hang out.
Areas
Little is known about what specific areas would be included within the underworld, other than what was included in the aired show. Most of these scenes were done by Joshua Gay. Other concepts can be found here.
A background made by Steve Lambe for Sean Scott in the year of 2005
Pilot concept from Dave Meritt of a traffic jam occurring in Hell http://beerinthemanshed.blogspot.com/2010/01/jimmy-two-shoes.html ---------------------------(This is the final version of the traffic jam sketch,which was supposed to be a sketch for Season 1,back in 2006,when the original concept was still a thing. (And after it was greenlit by Disney.) The first sketch of this image,at the bottom shows the date when it was drawn on October 24,2006 to October 27th and the final day of this sketch is unknown.) --------------------------------2 things to note: 1. (4 out 7 of the sketches show the same area as the final version,with different variations of how the traffic jam appears,what's on the side and buildings are either far or close and different as well.) 2. (While 2 of them are in the city,(somewhat)but,the towers are either looming or a bit far,like,imagine another town over or something like that but,still within Hells one and only city.)

Jacomo concepts from Kyle Marshall
An image of a man,hung above...well,something. Probably just to drive him mad,or something unpleasant is coming his way. Looks more or less like like your average mob thug or bank robber. (Note,and quote from Phil Postma: "These torture scenes were made up for Lucius's computer back when he was known as Lucifer.")
A man devoured and being digested by a snake.
A man buried up to his neck in (very hot) sand,sunburned x2 (ouch),about to be eaten alive or bitten heavily by ants (or sand ants),or worse,they could already be under him,biting him,made him into a nest or are constantly eating him as his flesh regenerates every possible moment it can with the ants still inside,who knows? Bad enough already knowing that he may have sand in his shorts?,pants? and possibly his socks and shoes,very bothersome and hard to get out,wouldn't you say?
An obese,naked man,with hands tied,hanging above fire,being poked by demons with pitchforks.
A man,cuffed down to a table,covered in dry blood,anxious and horrified at the thought of the (dry) bood covered pendulum slicing him open,as it approaches him.
A very obese man hanging above a pit (more or less) of spikes filled with doughnuts,torturing his conscience over hunger and his very life. Or just to ironically show the process he's about to endlessly repeat. (I say Ironically,because,well,he could've been a cop in life or ex-cop,turned murderer. Ex: The Golden State Killer,U.S. Navy veteran and former police officer,Joseph James DeAngelo.)
A punk-like teenager or kid,could be a kid,being hugged by red,smiling,teddy bears. (I say kid,besides guessing,is due to the fact,some kids have murdered out of joy and other twisted reasons. Ex: Eric Smith,Location: U.S.,New York,Year:1993 ,Age: 13 years old,Amarjeet Sada,Location: India,Begusarai,Year: 2006,Age: 8 years old,Robert thompson and Jon venables,Location: UK,event of where the crimes first minute starts,was at Bootle Strand shopping mall at 3:42 P.M. near Liverpool,Year: 1993,Age: Both were 10 years old,Jesse Harding Pomeroy,Location: U.S.,Massachusetts,Year: 1859,killed younger kids when he was,Age: 12-14.)
