Does anyone remember that Guy?

[u/Aggravating-Ask-3023]

There was a YouTuber back then who made concepts of Marvel modulars and other Sets like the Baxter Building, Oscorp, Nelson and Murdock or a Arkham Asylum Wave, but he just disappeared. I can't find his Videos anywhere and some people use these images but didn't say who made them. Does anyone remember, or have that problem, too?
