Based on its willingness to “creatively reinterpret spelling”, I’m going with Sagantine for the bottom one.
apcshields is correct for the first image. Unsurprisingly, no-one has got the second image right yet.
What website are you using?
Due to lack of options, is the last one Roger? I’m interested in what “Gaming Substrate” would produce
Not RogerBW.
(I edited in an answer upthread only after I noticed your question, but these are Dall-E 3 images from Microsoft’s “Image Creator”.)
Is it The Mighty Bort?
Not The Mighty Bort.
All 4 images from the same prompt, with the giveaway text removed. Remember, this is with the subtitle text, so guesses should include that for the rest of us to understand your guess:
Marx model citizen?
I wish, but almost certainly not…?
As much as I like the illustration , I don’t think I can replace Princess Hyacinth
Is this one RossM: Author, Dreamweaver, Visionary?
Not “RossM: Author, Dreamweaver, Visionary”
Is it raged_norm? I could see it reading “norm” as “gnome”.
It is not “raged_norm Steven not Norm”
Could this be Chewy, discoverer of final scoring?
Nope. To give a hint, I think the AI latched on mainly to two separate words, and had little idea what to do with the rest of it, except maybe some confused religious themes. Also, one of those two words doesn’t actually come up unless you tap the user portrait. I think that means it’s a former username? There’s probably some interpretation I’m not getting too.
Boydesian?
It’s not “Boydesian Garrick, the Ard-Rí na hÉireann (Probationary) “Garrick the Grognard” will do”
