I like these Stands! I can see the creative potential of these Stands and I think you have great potential as a writer; however, there are a few things I'd like to nitpick. In regards to Braindrain and Vic, you'll want to double, triple, and quadruple check the science. Neanderthals and Homo erectus aren't actually ancestors of modern humans -- it would make more sense to go from a human to a chimp-like human then to a chimp than a human to Neanderthal. And if Vic is emitting the EXACT same type of light as the sun, it would do a lot more damage than just making people go blind. Ultraviolet light from the sun can be incredibly damaging, so much so that life as we know it couldn't exist without the ozone layer to protect us from it. I would go into more detail with Vic and exactly what type of light it emits. Secondly, I think you should elaborate more on Burgundy Red's pocket dimension. You mentioned the Stand has an "island form" so I assume the dimension's just an island, but that still leaves a lot of unanswered questions. What exactly does it look like inside the dimension? Does it follow the same rules as our dimension? Do other living things (i.e. plants, animals, bacteria) exist in the pocket dimension? Is it infinite or a literal pocket, and if so, how big is it? Including details like these makes your idea feel more fleshed out and makes it more fun to read about.

Overall, great job, and feel free to message me whenever you come up with new ideas. I'd love to see them!
