So the sprites aren't what I considered plagiarism since to my surprise they are sufficiently different even though it's a similar design to the FR/LG sprites.

For Charmeleon, the sprite is closest to the B/W sprite, but not exact: https://bulbapedia.bulbagarden.net/wiki/Charmeleon_(Pokémon)...

For Squirtle, the sprite is much closer to the FR/LG sprite but still some differences: https://bulbapedia.bulbagarden.net/wiki/Squirtle_(Pokémon)#S...

The other images, however, crib from official artworks a bit too close for comfort.

In my original analysis I hypothesized this is due to token scarcity that reduces the ability for the model to be created: I believe that NBP images used 1.5k tokens for that image while the gpt-2-image used 7k tokens, but this is hard to test.
