Would it be copyright infringement to use copyrighted characters to demonstrate my animation skills?

[dayo20053d]

I wanted to set up an animation gig and I want to make a short video demonstrating my skills so that buyers can be confident when the purchase from me. I was wondering if I were to animate copyrighted characters for the demo video (Sonic, Ninja Turtles, Spider-Man, etc) would it be considered copyright infringement and would Fiverr take down my account? Thanks.

You can't use content/assets you don't have rights to, so no, you can't use Superman, etc. Wouldn't it be much better to demonstrate your skills by demonstrating ALL of them? Create your own characters.

Thanks for your input. The reason I haven't created my own characters is because 3D modelling is a skill that I've attempted for years and still haven't grasped it. Anyway, I had also messaged Fiverr support and the response I got is that since I would be making the animation, it would be my own work.
