In 2014, a 14-year-old injected himself with mercury at least 3 times because he believed it could turn his bones into metal after watching Wolverine. He also intentionally let spiders bite him on multiple occasions because he wanted to become Spider-Man. What makes the story so disturbing is how fantasy completely overpowered reality in a way that put his body in serious danger.
There is something especially chilling about seeing fiction taken so literally that it leads to self-destruction. Superpowers that exist only on screen became an obsession strong enough to push him into poisoning and harming himself in real life. It is a dark reminder of how fragile the line can be between imagination and dangerous belief.
