I love marvel, and recently comic book writers are trying to give us scientific explanations about how their powers work. I'm a fan of density controllers, hence my name, so I'm trying to understand Will O' The Wisp ability: I deleted some parts that are not required for this. The, in order to raise his density, he has to push its molecules closer together. If so, his volume decreases as his mass increases, giving it balance so the density remains unchanged. And I think the same thing applies to intangibility as the opposite. Is Will O' The Wisp's explanation accurate?
