What is a skeleton-style video?

It's Leaxor's illustration style: consistent animated skeleton characters that carry the story, instead of stock footage or a face on camera.

The point is recognisability. Every scene uses the same character proportions and the same visual language, across a whole video and across every video on a channel. Viewers associate the look with the channel before they read the title.

It is a stylistic choice rather than a universal one. If your content needs photorealism — product demos, real people, documentary footage — this isn't the right style for it.
