Then in all honesty, you should probably start smaller. But there are some tutorials around here for making various parts of fighting games, just takes some specific searches. The thing is, you’re not really going to get a tutorial that takes you A-Z on the entire process, so you really need to learn the actual principles of design first.
For example you might want to start of with the sidescroller template. Then find a way to make the camera work. There’s at least 2 current threads floating around right now, just join the discussion.
And then move on, small steps, tackle one problem at a time and find solutions for specific problems and not a project as a whole. Making an actual game is no simple task and it takes a lot of time and effort, especially if you’re new to this.
