Otherwise I couldn't possibly create an All Elite Wrestling logo because it would not have existed in 2015.
It really comes down to how you describe and phrase, I had hard time getting it to draw Macho Man and Ultimate Warrior so I added multiple descriptors like "WWE Superstar, wrestler, Macho Man Randy Savage" to otherwise simple requests to get it to sort of work, at least some of the time.
Some names are just too universal to be recognized as a simple specific entity for the AI. It's like says "Draw a football" but getting a soccer ball.
Hulk isn't immune to it either, specially request involving comics will auto-add the Incredible Hulk or Green skin, but he somehow works the best even without descriptions.
