A prototype...for a show?
That's right. These are 4 fake screen shots for the prototype of SatAm Sonic tv show. These likely appared in a trade magazine or possibly a brochure for the show. They are shaped like that, because it was to resemble the old style shape of the TV screen. (So, isn't that historical to see...) With these shots, you can see how the original idea for the show was to be more like the Fleetway UK comic book with characters from it like Johnny Lightfoot the Rabbit & the sort of "eggbotnick" type villain mash up. But now, let's explore what's going on here!
The characters:
You'll notice the co-star character here ISN'T Tails & that's because the show was developed before Sonic 2, so they didn't know about him/he didn't exist yet. Instead, he's replaced with Sally "Princess Acorn" the CAT in the red dress. Of course she's blonde and is basically a human woman with a cat head on there because reasons. (The female animal always has to be a hot human.....you know..../Sarcasm) Was this a leftover from "Madonna"? Probably not, as that failed character was too obscure & this show did 0 research ever.
Token Female:
Yep, it's the token female! There was literally no reason to have only 1 female character/literally any of the 'little animals' the other characters are based on could have been girls but no......girls are icky, we only want 1 of those so Sonic can act a fool over her & she can lord her intelligence over him at every turn & crap on him 'like girls always do to all boys'. (Token-Female is a thing, it's actually super interesting to research if you look back in this era of shows/books/whatever you'll find teams or whole casts of characters where it's literally ALL guys and only 1 girl consistently. Some will have 'peripheral-2nd-girl' where a 2nd one will show up only sometimes. Villains don't count. But do look it up, more stuff than you think is Token Female, so it's probably not a shock that this is too. This is like a proto-"The Girls Curse" that you get in action figures and merch where "Eew no one will buy an icky-gross-boring girl item let's never make them".)

1st Screen- The Resistance is Born
This shows you the dystopia setting was always there, & Sonic and co were to fight robots
2nd Screen- A Hero's Reward
This shows you that Sonic was going to be a sucker/sap for Sally and be lusting after her so she always has to repel him and his unwanted advances (gross) as a 'joke' in the show. Here, she tricks him into kissing a dead fish on the mouth. You can see this "Girls are smart boys are dumb" theme continued into SatAm as Sally was the charismatic leader of the Freedom Fighters and always told Sonic what to do.
3rd Screen The Freedom Team!
This shows the whole cast of good guys before they settled on Freedom Fighters (which sounds better) And look at what a bizzarre cast & strange choices they made.
You've got UK Comic's name Johnny Lightfoot-
and he's still gray with a red shirt, but now he ha s sunglasses and a really extreme wide lower face? What is that? Probably EVERYthing with him is an attempt to make him NOT be 'bugs bunny'.
Porker Lewis-
Doesn't look UK at all, he's now punker lewis? Why a mowhawk? Wierd glasses too, plus a black leather jacket (animals wearing each other's skin! Always hilarious!)
Joe Sushi-
A walrus....but it's brown, has no tusks, the face looks like AOSTH Robotnick (doesn't it!) and is in some kind of metal Iron Man suit? Because walrus has no legs??? Clearly this became Rotor/Boomer & they turned him purple later for SatAm.
Flicky-
They didn't rename him but dressed him as a chef/white outfit? Why is the bird not blue? What are you doing with a chef bird that wears no pants?
Tex-
A tiny penguin. Inappropriate name on purpose for 'the laffs'...yeah ok, but why is it small? The other characters are supposed to be people but this guy doesn't even have hands and is perhaps knee high to everyone.
Chirps-
Baby chicken creature here, again, it looks like the 'little animal' that comes out of the robots that ARENT PEOPLE yet is somehow also people for the show. It was setting itself up to make no sense.

Why are all the other animals normal colored except Sonic?
Why is Sonic the only one who is naked?
Why are 2 of them 'animal-animals' and not people-animals?
Why is Princess Acorn Cat in a red evening dress* to fight battles and run around??
What were they going to do with a cast so big with non-Sonic characters?

4th Screen Dr. Robotnicks Automatic Robotic Transformation Machine
"Dr. Robotnick's Reign of Terror Strikes The Planet Mobius" - It wasn't yet shortened to The Roboticiser here, clearly. This shows the main plot device for the show, which is he's making slaves of everyone. This is the only shot where you actually see the main villain. Notice Acorn is on one side tied up, with a generic probably some bear guy also, and then wacky robots are coming out the 'exit'. Robotnick is labeled, but the label is really tiny. Note also that it is shaped like an egg.

*So why does she wear an evening dress/cocktail dress?
Because she is the only female character and therefore must be sexy & appealing to men at all times. What's her cannon age? Who cares! Cat boobies! Cat thighs in a short skirt! Corset-style waist! Go!

So, this panel of proto-screens turns out to be a bit of an article-explanation, but it's important to take a look at history and how things started...then see how they changed over time. (In this case, for the better!)
