My favourite incorrect bitching about art was for the Transformers cards, with people crying that they were just cartoon screenshots. They straight-up just weren't, being fully new art that just mimicked the cartoon style. Not to mention:
- Megatron being a tank, not a gun.
- Young Spike and Goldbug somehow coexisting.
- Slicer and Flamewar being there are all. Slicer was created four years after the cartoon ended (and was different colors), and Flamewar was created EIGHTEEN years after the cartoon!
