I'm surprised the author didn't put Transformers in here.
It's originally a US/JP crossproduction based on licensed Japanese toys, so it'd be a little out of place with these series that were fully American made (unless they were to use something like the live action movies for a piece like this).
Fun fact: The human liver can regrow if anywhere up to 90% of it has been removed. The reason we can still die of liver diseases is because it can be damaged beyond its capability to repair itself.
This looks to be a collage rather than a completely original work. There's weird outlines on everything, the texture on the clothes seem at odds with everything else, the damage on the halo is poorly drawn on, and the earrings are just shopped in.
