>>55330535This one is really just coincidence. Hot Peppers are THE obvious choice of theme for the first fire/plant. There are legitimately probably thousands of hot pepper fakemons. With the idea of green and red peppers it's not at all surprising that through sheer volume at least a couple would turn out two-headed with a similar shape to Scovillain. No matter how Scovillain looked there would probably already be a fakemon similar to it.
>>55330558This one is more suspect. Unless there's some obscure fact about dolphins I don't know, the combination of concept and animal feels oddly specific, especially with the heart added on. Although again, with the sheer volume of fakemon designs out there I wouldn't completely rule out coincidence. But yeah, definitely a stretch.
>>55330525I don't actually know the context here, but it looks sketchy. The concept isn't really that specific, but there are a little of details that seem too close to be coincidence. The eye color and red eye-liner. The general proportions and the fact that the bush happens to have berries. Seems more likely then not to be a copy, but not quite on the same level as Palafin.
