Characters Interaction with Mecanim Animations

Hi,
i’m trying to use two animations on two different characters.
i’m using mecanim for moving my characters.
the two animations are intended for create interactions between this two characters.
the first animation is of a man that takes the second one from behind and then he kill him.
the second animation is of a man that is killed.

I would know how can I syncronize the two animations, so this will be realistic, and how can i place the first character right behind the second one when i press the kill button?

I’ve created several 2 & 3 character interactions in 3D although none have been specifically for Unity.

From my limited research on this subject - I believe the best approach is to animate both characters in the same scene in a dedicated 3D application. However I do not know what the best setup is once the animations are in Unity - for best visual fidelity.

The development team for Ori discussed in some detail animating 3D characters and then later turning them into sprites to be used in engine. One of the many reasons they choose this pipeline was to have tight character interactions between multiple characters.

For 3D character interactions additional in-depth research is required.
