Does someone knows how to put an enemy over another in the side-view battle?

Hello, I want to do a type of enemy that has several "sub-enemies" that need to be destroyed before one can kill the main enemy, like in those classic FF games where you had to destroy the turrets of a floating ship IIRC, but whenever I try to place the small ones over the big one, instead of overlapping it, they end up behind it or moving away from it. Is there any way to do this?

I don't remember how the Z order is drawn in the side view.
you could set it so that Z is calculated based on XY, or forced to a single value, or forced to be relative to something else.

the point being, you can modify it.... it's all a matter of knowing how it is set by default.

Do I need a plugin to do that?

Have you tried either "Transforming" the enemy or setting the "next" enemy to hidden and make it appear/transform after the previous one is defeated? Or do you want everything to ve visible at the same time?
If you want an overlapping "phase" fight, either a transform or unhid next enemy should work.

Let me put an image to explain myself better of what I want to do:




The archer-looking enemies will vary in numbers, sometimes there might be just two, other times four, and so on. I could make them all in one picture and have a picture for each type of battle, but I want the player to be able to focus their attacks on an enemy and that it disappears when its defeated. Putting that it changes how it looks after certain amount of HP has been taken from the whole might work, but I will feel it less organic, or something. Maybe If I put the whole cloud and most of the body as an image, and only leave the head as a target it might work.
