How to make Mortal Kombat fighting game?

It's not like there's a tutorial about how to exactly make an entire sucesseful fighting game... The question is simply too broad.
Start by learning how to make a custom movement, which is probably important for getting it to be consistent. TheGuyOverThere123 channel has some great tutorials on custom movement.
Now, about AI, that's a tough one. I recently studied how MUGEN AI works so I could recreate stuff like this in Fusion, and in the end, the logic is quite simple, but there's not a recipe for all movements, each movement will have a very specific set of rules.

If you've never made a fighting game before, my advice would be not to try and make/re-make Mortal Kombat, rather make a fighting game inspired by Mortal Kombat. I say this because if you make a game inspired by MK, it doesn't have to work exactly like MK, it just has to work. You also have the freedom to add your own systems/sounds/characters etc.
If you're looking for techniques, try these:

What NaitorStudios said is good advice - start working on a custom movement system. Whether you do the sprites first or use place holders, you need plenty of animation frames for smooth movement and to allow the player time to react to what is happening.
If your gameplay area is larger than the screen, you need to make a camera system that centres on and tracks the action as it's taking place. It should move smoothly so players don't get motion sickness.

Understand states/finite state machine - this will help a lot when creating AI and also managing characters - you don't want a player(or the AI) being able to attack while they're stunned/knocked down etc.

Controls. Using the above example, there are times when you want to disable controls. Don't use the ignore input command, instead put your control schemes in groups and enable/disable the group when needed.

If you don't know what hit boxes and hurt boxes are or how to use them, read the article linked above. You can also use collision masks but for a game like MK you should use hit/hurt boxes.

Creating AI. Make the computer controlled fighter have the same control scheme as the player - this makes it easier when coding for the 2 player mode/switching to an AI driven character. What I mean by this is both the player and the AI should have something like if UP and KICK are pressed, do a flying kick. The AI should decide to virtually press UP and KICK.
The AI should always be asking questions of the player's character, generally starting with 'how far away is the player' - if the player is considered out of range for melee attack, is the player using a ranged attack e.g. a fireball? Should the AI use a ranged attack or move closer? Is the AI playing aggressively or defensively? The smarter AI should want to control the play area.
Is the player attacking? If yes, does the AI block or duck? Counter attack? How skilled is the AI - make it's skill level/reactions adjustable.
Should the AI attack?
Divide your attacking moves into groups of ranges, e.g. how far from the player the AI character is - short range, medium, long range etc. Activate the relevant group depending on the distance the player's character is from the AI character.

I find using a flow chart helps when creating AI for fighting games, here's one I made to help me create AI on a fighting game I made a while ago:

If you need concrete examples, I'm afraid you'll need to pay a developer to make it.
People won't simply give you their projects, nor make entire tutorials just because you ask, specially for free.
There are plenty of developers to hire.

And if your videos are real projects that you made, I do remember seeing a MK HD remake long time ago, thought it was a MUGEN tho. Those look great.

Quote from pdesigner

I used to make games on a more advanced engine like Cry Engine 3, but I gave up because of the license... Overall Fusion is friendly and I like this engine also because of easy import to Android and iOS which was my main advantage.

What NaitorStudios said. Noone is going to make such a specific example for you, for free.

It also seems strange that you would want to remake MK if you're concerned about licenses and intending to export to Android and iOS - you'd obviously be in breach of copyright / intellectual property laws. Only a matter of time before you receive a "cease and desist" (I bet they're being extra strict about it now, with the new movie series drawing so much attention).
Try being original instead - if you're capable of creating a MK copy, you're probably capable of making an original fighting game, and then you might even make a bit of money out of it.

Sorry my reply was too simple for you, it was a direct response to you asking a simple question. I've played fighting games for a long time too, including the original MK when it first came out in the arcades. I'm pretty sure I have enough knowledge to remake it in Fusion but I have no interest in doing so.

If you mean like a fighting game template I think there is already some examples for this
I might make a tutorial myself when I have time, but also the last one I made is almost a year old already...
What I mean by this that people don't have the time to make "full game tutorials like this", especially if as specific as you mentioned, it's like "How to make an RPG tutorials" they are more like templates and combinations of different mechanics (Movements, dialogue system, inventory... etc) but you won't find tutorials like: "How to remake The Legend Of Zelda: A Link To The Past in X engine" because it's simply too broad

To make games you have to know how to make mechanics for yourself... or atleast pay for someone to do it instead
That can be achieved by having a better experience with the tool and improving your logic and programming skills

I would look up an old game called Pit Fighter, and see how that works, and how it was made. There are multiple examples of some fighting games you can start with by the community that can help to

Modern day Mortal Kombat has many layers of technology that runs the Injustice and MK games that is not easy to duplicate.

it's a very hard work, I've been working on the MK engine for over a year and I know what I'm talking about.

That looks amazing Kage, would love to see a demo vs an AI opponent.
