Tagged "rejected 1P & 2P characters", these are likely "Phil John" (left) and "Michiko Nakajima" (right), the names of the original protagonists according to RetroGameTest's Metal Slug History videos, probably from the early development period when the tanks were the main characters. The 2P character has a hair style that strikingly resembles that of Fio's, and she even wears glasses to go with it.
Concept art for dialogue scenes between characters, for the opening stage or between levels according to the Metal Slug official guidebook. From left to right: Michiko Nakajima, Phil John (top), different Michiko? (bottom), early Morden (top) and Satiko Suzuki (bottom).
Unknown characters drawn by Max D., found in the Other gallery. Possibly early characters from the same era as those above; the girl is likely an alternate design of the rejected 2P character.
Ivo speculates the top-right character is the same as the unused soldier who pops out of tanks from various angles.
Sophia in various get-up. Otherwise only seen in the Official Guidebook, they were probably unfinished pieces for the Special gallery.
A tiny doodle of Satiko Suzuki, the grieving girl in the bad ending. She's walking a dog instead of praying in this picture.
Animation tests for the player character; their knife attacks on the left (including a fancy reverse kick and mighty punch) and entering the Slug on the right. Probably just the artist getting colourful.
The guy resembles Amadeus from Metal Slug 4, but this picture was drawn during the development stage of Metal Slug 1, with six years of gap in the time period between them.
"Devil Rebirth" Morden! A goofy bit of art depicting a bald Morden as an Allen O'Neill-like musclehead.
Special Old Lady Unit
"Special Madams", they call her.
She looks as if she's about to shove that rocket launcher up someone's ass.
But in the game, however, all she really does is to act like... civilian, a non-combatant.
The same lady, looking more ghoulish than ever. Those poor villagers get no respect!
From page 27 of the PlayStation version's manual: Chris Key, Alexander Suvorov and Rumi Aikawa. These characters appear only in the exclusive Another Mission mode, albeit as P.O.W.s without unique appearances. Notably, this is Rumi Aikawa's first appearance, six months before Metal Slug 2 hit arcades.
This must have been a really early design of the Slug Tank. The crew is unprotected, no hydraulics that allows the tanks to jump are visible, and there are no armor platings that shield the threads.
Two particularly outrageous early concepts for the Metal Slug, if the Metal Slug Official Guidebook is to be believed.
Arts for mission 1 of Metal Slug 1. If you look at the Slug Tank in the pictures, you will notice that its pair of Vulcans are missing, as well as strange barrel sticking out of the rear and missing piece of hardware on top of the turret.
The threads also look weirder. Also, the two things that stick out from the side of the thread shield are missing, too.
Early (top & middle) and final (bottom) concepts of the Metal Slug. The early versions look much more cartoonish since most of the parts are round and seperated; the middle image shows some of the exaggerated animations the Slug would have had. The final design is more rigid and tighter looking.
The never-used SV-002. It's more sleek, and has a machine gun and a missile launcher instead of a vulcan. Its cannon's caliber is smaller, and the chassis profile is much lower. The headlights have also moved further to the rear of the top of the turret. The mineplow is also higher off the ground, and the all-bearing antenna has been changed from being cylindrical shape to a shape that of a cutter.
The Middle-Son class submarines. The older variant on top, Middle-Son 1986, has been used in the final mission of Metal Slug 1 after you fall down the bridge when Morden blows it up.
The newer one below, Middle-Son 1999, is used in the first mission of Metal Slug 1 as a derelict submarine.
At the top-left is the old design of Type-2 Di Cokka. To its right is a very funky design of it that got scrapped. The final design is on the bottom; it shows how close the tank looked like M3 Lee battle tank used by the Americans during World War II.
In the Official Guidebook there's an inset for the KT-21, which survived long enough to get a full set of sprites (based off the top-left design) but never got used. Based off its animations it behaved much the same way as the Di Cokka.
Early (top) and final (bottom) concepts of the Type-2B Melty Honey.
The first picture shows the Melty Honey as a battle tank. The ones in the second and third makes it resemble a fire-support vehicle, with its open top crew compartment. The difference between the second and third designs is that the third has the spikes on its front armor, while the previous one does not.
Early (top) and final (bottom) concepts of the Type-5 Iron Iso assault tank.
The top-left picture makes the tank resemble the German SdKfz173 Jadgpanther, although the latter resembles the PzKw VI Tiger. But more importantly, the first picture shows how the designers were planning to add more sophisticated projectile/armor characteristics into the game, seeing how the shell is being bounced off of the top armor of that vehicle.
Anti-aircraft gun. There was suppose to be another AFV for the Rebellion designated as "Type-6" which serves as an anti-aircraft vehicle. But it seems that it was scrapped due to the fact that there were no controllable aircraft for the players in Metal Slug 1.
Another mobile ack-ack gun that never made it into the game.
Early (top) and final (bottom) concepts of the Tani-Oh, the level 3 boss from Metal Slug 1.
The first picture shows a blocky tank with three turrets and a lot of and barrels. The second image shows a huge tank with just a huge turret with a huge gun. The third shows a huge turret mounted on its chassis that has even more smaller turrets with cannons mounted on it. It also has guns located on the side of its chassis.
The final two, however, shows a completely different picture with the majority of its smaller cannons replaced by just two monstrous guns with two minelayer/Vulcan pods on each end.
Early (top) and final (bottom) concepts of the Shoe & Karn, the level 4 boss of Metal Slug 1.
Note the difference in armaments between the old and new designs. The old one carried an anti-aircraft cannon on the back instead of a cruise missile. The new design also has a longer barrel for the gun, as well as twin auxiliary guns below it. Mineplow has been added to the new design, and the new turret now resembles that of the Girida-O's.
A destroyed World War II German PzKw IV Ausf. H Panzer tank, which is definitely not in the game.
Early (top-left) and final (rest) concepts of the R-Shobu. The first and second pictures make the damned thing look like a child's toy, while the fourth makes it look like a joke, and the third making it much more respectable than others.
Notice how the aircraft looks considerably different by comparing the fourth picture to the others.
Early (left) and final (right) concepts for the Flying Tara and Eaca-B. In-game the two planes use the same graphic, but the early designs show them with unique models, closer resembling a dive-bomber and fighter-bomber respectively.
Early (top) and final (bottom) concepts of the Hairbuster Riberts, level 2 boss from Metal Slug 1 and level 5 mini-boss from Metal Slug 3.
Not much has changed in design, except that the two engines located on its wings were replaced with a single engine that is placed on top of the aircraft.

If all UFOs come from space...
translation from Shmuplations
A schematic for an alien UFO. UFOs do tie into Satiko Suzuki's bio, apparently, but how much space stuff had they planned at this point?
I have... no clue... what these... are supposed to be.
Gundam spin-offs, maybe?
But I do know that there was a seperate project for developing a spin-off of Metal Slug 1 that was going to include these robots. However, the project was cancelled due to lack of interest from the staffs due to the fact that Metal Slug 1 was suppose to be World War II oriented, not sci-fi.
Middle-Son 1999 missile submarine. The hull looks slightly different from the one used in the first mission of Metal Slug 1.
Art for mission 1 of Metal Slug 1. That's the wing of the crashed-landed Tetsuyuki gunship that you fight as the boss. Notice how many things are different, including the wingspan and the wooden platforms that you use in the game to climb up to the wing.
Art for mission 3 of Metal Slug 1. That tank is not suppose to be there, let alone exist, in the game.
Art for mission 3 of Metal Slug 1. Note that the gun turret in the picture is not in the game, but just a pile of sandbags blocking the entrance.
Art for mission 4 of Metal Slug 1. Sure, they had that shack in the game, but no machine gun was mounted in one, either.
For art sourced from the "Other" or "Special" galleries, or simply doesn't fit in the other categories. There's some far-out crap in those sections, some of it possibly intended as serious concept art...
... and then there's boob rockets. I've no idea who the woman is or its relevance to Metal Slug, but it's in the game, so...?!
Assorted female characters. The top-left woman is wearing the same uniform as one of the early Sophias above... only with grenades in her hair. The top-right woman has "Metasura" (メタスラ), an abbreviation for Metal Slug on her forehead.
The bottom two have fully painted illustrations and bear vague resemblances to Eri, but resemble no one in this game. I've been emailed about three times saying the last character bears a resemblance to Captain Harlock, emphasised in these images. I never quite saw the similarity, but if people keep telling me, may as well say.
Well, would you look at that. Mazinger Z with an ugly face attached to it. Not used in the game, but it says "final weapon" at the top right of the picture.
An explanation for the stuffed bear item. Metal Slug 2's concept art would feature new innovation in bear-communication technology.
Mitsumi (braided) girl doll
Metal Slug 2 would also expand upon this grisly bit of lore.
"Special Box (with sauce)". An item that doesn't appear in the game. (will anyone dare transcribe/translate it?)

This must be the artificial heart that the SBS units use.
I assume that Max D. had too much time on his hands.
One of the game's creators, Andy, is drawn here by Max D. An incredibly geeky aura surrounds him.
Early logo designs, from the Official Guidebook. The one second-from-the-left looks closest to the final; the two beside it have similarities to the logos from In The Hunt and Gunforce.
Concept art is sourced from the Metal Slug PlayStation Art Gallery, the Metal Slug Official Guide Book, the Metal Slug 6 Art Gallery, the Metal Slug Anthology Art Gallery the Metal Slug 10th Anniversary website, and the Metal Slug Attack Illustration Gallery.
