Animated Outline

Animated Outline Shader
The idea here being that there is some sort of animated outline to show off the state of a character.

After researching the web, and finding various posts asking about how one would implement it, I came across Glow Highlighting in Unity where a great starting point for the implementation is shown using Unity’s Command Buffers.

Luckily, I’d already spent some time looking at MRT, which helped a lot to understand the theory behind this technique.

Essentially, once the outline is set up on your geometry, and its placed on a render target then there are a lot of things that can be done to it, for example, using UV scrolling with a pre-made texture to give it a sense of movement.
